imo, it's a bit unfair to myself if I don't give myself an experience that is likened to an orgasm, but better.
Well, they’re wrong about that. Oh, Alia, the only thing better than an orgasm is an orgasm while doing Bitcoin. You game?
(Logically, assuming arguendo that there be such a thing, would you give yourself an experience better than an orgasm—and only do that once, ever?) |

Can't wait to receive transactions from you hard and fast. And in nine months, maybe we'll have a new multisig wallet.
Well, there’s something which will grow in value. Now that you’ve got me hard, and I mean NP-COMPLETE hard, I want for you to wrap those luscious legs of yours around me for a horizontal dance as I fill you up with me. Let’s establish a rhythm with my continuing description of hash functions... |

I'm interested in weed, LSD, Xanax, Addy, shrooms and so on. Never tried them and would love some advice/feedback before buying them
Well, since you asked: I don’t do drugs. If I did drugs, I would not have the technical prowess and writing ability which together have earned me 427 merit (and counting) within 18 days of active posting—numbers which currently put me as #5 on this list, whilst still at Member rank with 98 activity. N.b., I am here discussing drugs which are strongly mind-altering (“get you high”). Contra much propaganda on the subject, there is a reason why certain things technically categorized as “drugs” are separated from others. I can sum up the matter succinctly, by example: In NASA’s Mission Control room during the Apollo missions, there was always a forest of half-empty coffee cups and overflowing (tobacco cigarette) ashtrays. After a long shift in one of the world’s highest-pressure intellectual jobs, I’d guess that some of those guys probably went for beers after work, too. But I guarantee you that not one of them ever “did drugs” in the sense people mean that—and moreover that if they had, then man never would have set foot on the moon. To be clear, I’m also not what I contemptuously call a “Drug Warrior”. There is a commonplace false dichotomy which pushes people to either condone drug use, or support idiotic régimes of laws which start by trying to stop people from willfully destroying themselves, and end by trying to ban strong crypto because (oh no!) drug dealers might use the tool of cryptography just as they use cars, postal scales, etc., etc. Meanwhile, drug laws in the form they exist today do little except help make drugs “cool”. There’s nothing beneficial about them. Thus, speaking here only as to personal decisions and social mores: If you say about drugs, “Never tried them”, then I say, good for you. I’ve also never tried stabbing my own eye with a fork; it’s an experience I can do without. My opinion on this matter is quite strong. I’ve written about this before; I will here quote only a brief excerpt, but I encourage you to read the whole thing: What some people just do not get: Before there were drug laws, there was no drug culture. Libertarians, hippies, and Drug-Warriors all share the same blind spot here.

Bitcoin shows no mercy for those who lose their private keys. You have ultimate power over your own, and ultimate responsibility for yourself. Mess up, and you will lose everything—nobody can help you. There seems to be a lesson there.
You have only one body. You have only one brain. Mess those up intentionally, and you will lose everything. Have a nice trip! ☠
That’s my “advice/feedback”. You’re bright. You’re pretty. You know how to have plenty of fun without drugs, to rather understate the matter (and as you may have noticed— so do I). You have a knack for Bitcoin. And consistently with your interest in Bitcoin, you evidently desire a self-directed life. You have so much going for you. Please make the right decisions, and don’t mess it all up like an irrevocable spend of your whole wallet to a burn address. Drugs are 1111111111111111111114oLvT2 for your hopes and dreams and plans for the future.
(Note: I wish I’d seen this earlier. I’m watching your posts, as I said I would; but I just glance over the top of the list from time to time, and a short one sometimes gets missed between others.) |

Thanks! I'll be back in a few hours, looking forward to you exploring deeper depths of my cipher with all of your keys (start with public and end with private, please)
The key between my legs shall decrypt the cipher betwixt yours, o Alia. Till then, your homework is to solemnly contemplate how many readers are pleasuring themselves whilst watching you learn the basics of applied cryptography. Protip: Kerckhoffs’ Principle states that the security of a cryptosystem must rely solely on the secrecy of the secret key; whereas the cipher may be known to all. Published in papers. Released on the Internet. My key is secret: There are no (unencrypted) photos of it on the Internet. Whereas your cipher is quite public, is it not, my dear exhibitionist meretrix? Does the thought thrill you? I know it does, but please do say. I’m not the only one who wants to hear it. How much do you enjoy Kerckoffs’ Principle, as applied to you? Aside—I noticed you advertise some kink. The security of the Bitcoin mining system (based on Hashcash) relies on something called a partial preimage bruteforce attack. We’ll get to that later, if you’re naughty. Also, if you’re nice.
This is better than Shakespeare.
Oh, really? Have you forgotten Shakespeare’s evident taste for the taste of a woman’s cipher? Hamlet: Lady, shall I lie in your lap?
Lying down at OPHELIA's feet
Ophelia: No, my lord.
Hamlet: I mean, my head upon your lap?
Ophelia: Ay, my lord.
Hamlet: Do you think I meant country matters?
Ophelia: I think nothing, my lord.
Hamlet: That's a fair thought to lie between maids’ legs.
...or...“Fondling,” she saith, “since I have hemm’d thee here
Within the circuit of this ivory pale,
I’ll be a park, and thou shalt be my deer;
Feed where thou wilt, on mountain or in dale:
Graze on my lips, and if those hills be dry,
Stray lower, where the pleasant fountains lie.
Etc... There is plenty of sexy Shakespeare scattered about. Oh, and Alia, I hope that gives you some idea of what I plan to do to you. |

Let’s start with the basics. We’ll get to elliptic curves, after I fondle yours for awhile while giving a conceptual overview of public-key crypto, symmetric crypto, hash functions, etc.
Also, I have changed my mind about the spanking. I will spank you just for fun.
Public-key ciphers
A public-key cipher uses two different keys: A public key which is not secret (as the name implies), and a private key (also sometimes called the secret key). These two respective keys are related by a mathematical function which lets messages encrypted to the public key be decrypted by the private key; also, by similar means, the private key can produce forgery-resistant digital signatures which can be verified using the public key.
The advantage of a public-key cipher is that the public key can be—well, it can be made public.
Bitcoin uses an elliptic-curve cryptography (ECC) cipher with curve parameters called “secp256k1”. Remember what I said about the mathematical function which relates the public key to the private key. Here, the function is based on something called the elliptic curve discrete logarithm problem (ECDLP). Don’t worry about what that is right now.
A typical Bitcoin transaction must be bear a verifiable digital signature from a private key. The corresponding public key is the basis for the type of Bitcoin address with which most users interact: Old P2PKH (Pay To Public Key Hash; addresses starting with a “1”), or with Segwit, P2WPKH (Pay To Witness Public Key Hash). The public key is not used directly to form the address: Rather, it is hashed, and the hash of the public key (plus metadata) makes your Bitcoin address.
Symmetric ciphers
A symmetric cipher uses the same key for both encryption and decryption. Obviously, this key must be kept secret! The most commonly used symmetric cipher today is AES; you have probably heard of that.
Hashes
A hash is a one-way compression function which takes an arbitrary-length input, and produces therefrom a fixed-length output. Take for example the SHA-256 function. You can feed into it any arbitrary amount of sexy bits and love-bytes; and its output will always be 256 bits (that is, 32 bytes (that is more precisely, 32 octets)).
There are many types of hash functions used for different purposes in computer science. Many, if not most hash functions are unsuitable for cryptography. A cryptographically secure hash function must have certain properties which make it infeasible for attackers to do such things as finding two different inputs which produce the same arbitrary hash (called a collision), or finding an input which produces a certain particular hash (called a preimage attack).
I believe I do not exaggerate when I say that hashes are the single most important building block of Bitcoin. Hashes are everywhere! They are used to build the Merkle trees which tie together all the substantive contents of a block; they are used to produce a Merkle chain of one block to the next, i.e. this “blockchain” thing you keep hearing about; a partial preimage attack is the basis of block generation, a/k/a mining...

Consider a hash function, such as the SHA-256 algorithm used by Bitcoin in many places. Among other properties, a cryptographically secure hash has the property that for any 1-bit change in the input, on average, 50% of the output bits flip. See how this works:
[...]
Was that explanation sufficiently clear, or do I need to somehow involve a spanking? I know you like that; and I may need to apply such measures, if you fall behind in this lesson.
So, this implies that it's very hard to crack a private key, right? Am I understanding it correctly? No, a hash function does not involve any private keys. I will now briefly explain the most common types of cryptographic algorithms, and their purposes... (Get back in my lap, and give a good grind with me in you. You don’t deserve a spanking, because I omitted the prerequisite background information.) |

I will presume that Alia needed a masturbation break. For this class in applied cryptography, that is called “homework”.
Funny because that's actually what I just did Good girl. I hope you got good avalanche effect. (Will explain what that means...)

I have here chosen 'b' and 'c' for the sake of example, because ASCII 'b' (0x62) is one bit different than 'c' (0x63). ('a' (0x61) and 'b' (0x62) differ in 2 bits. Well, that’s another lesson.)

I'm down for some 3 of 5 multi sig if alia brings some friends..
Well, Alia? In Bitcoin multisig, we’re still talking ECC. Have you any friends whose elliptic curves could have their public points (a/k/a “nipples”) hashed together with yours? As Segwit fans, this will involve Pay to Witness Script Hash. That’s more secure: A 128-bit security level rather than an 80-bit security level in old P2SH, in case any of your friends turns out to be a malicious signer. Also, because people are witnessing this. (With a thread like this, I also wonder if she’s looking for a pseudorandom gang-bang. To use technical terminology.) |

Confidentiality: You want to be sure that nobody is watching our activities here. Oops.
Well, I guess that ship has sailed. But if we wanted to keep this carnal conversation confidential, we would encrypt it using a symmetric cipher (same key to encrypt and decrypt). Depending on the protocol, we would either use a key agreement algorithm to establish a shared secret key across an insecure channel, as in the TLS used by your web browser (for decent ciphersuites)—or use or public keys to encrypt the symmetric key, as in PGP. Now, which protocol are we using at present? With you grinding in my lap, methinks the appropriate protocol is slow, deep, and hard. |

- Integrity: You want to be sure that our coital connection is not tampered with by a “Man in the Middle” attacker.
We will use a MAC (Message Authentication Code) to assure the integrity of all fluids exchanged. One common example of a MAC is HMAC using a hash such as SHA-256. HMAC is a special means of hashing together a shared secret with sexual libations a message, such that the fluids message cannot be forged by someone who knows the key. (P.S., I meant what I said about the taste of your cipher.) |

Loving this already. I guess a threesome is out of the question
Secure multiparty computation? We’ll get to that... |

Authentication: You want to be sure it’s really me down there, and not an imposter.
You will require me to digitally sign my cock before inserting it into you. I will use my private key to create this signature; and you will use my public key to verify it. Note: This is also how Bitcoin transactions are verified. (Yes, all Bitcoin transactions involve my cock.) |

First, let’s get our concepts straight: - Authentication: You want to be sure it’s really me down there, and not an imposter.
- Integrity: You want to be sure that our coital connection is not tampered with by a “Man in the Middle” attacker.
- Confidentiality: You want to be sure that nobody is watching our activities here. Oops.

Hello, Alia. Now as I hold you in my lap and press myself against your entrance, I will teach you to authenticate my cock using public-key cryptography and a hash.

[Note: One of my motives which led to my unlucky assocation with Alia was my desire for someone to work with for an erotic Bitcoin art project. For now, I will leave my intentions a mystery; but girls who have really gone Bitcoin should feel free to contact me if curious. Moreover, I will revive and continue this thread if/when I have suitable other(s) with whom to make cryptolove. For I believe in the virtue of Ciphersex, q.v. — nullius, 2018-03-08]
I’m here with the lovely Alia. In case you don’t yet know who she is, Alia is the saucy lass who posted this two days after signing up for the forum: I think I'm an outlier. If I have 100 merit in 30 days, I'll eat all my words and post a vid of me masturbating to a merit infographic
Whereupon I wrote her an open letter. We hit it off. Alia is enthusiastic about cryptography, a subject about which I myself am passionate in every sense: I am thrilled by the touch of numbers, the look of elliptic curves, the scent of algorithms in rut, the sound of exponential moaning, and most of all, the taste of Alia’s own private cipher. I offered to educate her: Of course, I’d be happy to help you increase your technical knowledge. I’ve spent plenty of my time doing that for people who are far less—charming. When you see what secp256k1 looks like, you’ll understand my remark about your elliptic curves: ( N.b., that’s the same equation over the real numbers, and not over a finite field as the crypto actually works. https://en.bitcoin.it/wiki/Secp256k1 Nevertheless, it’s fun.) What is your knowledge level of cryptography concepts? E.g., could you explain in basic (non-mathematical) terms how the ciphersuites in PGP, TLS, etc. fit together? Symmetric cipher, asymmetric cipher, hash function, etc. Also, concepts such as the distinctions between integrity, confidentiality, and authentication.
I can teach you all these things, and much more. I am looking for the starting point.
Now, how better do you learn? In my lap, or on your knees with your head betwixt my legs? I should mention, “in my lap” involves penetration. Penetrating insights into your most private cipher.
P.S., if I can’t make you cum whilst instructing you on ciphersuites, then I will have failed as a teacher.
P.P.S., I do like helping others. Do you want to take this show public with a “NSFW”-marked cryptography instruction thread in Off-Topic, or would you prefer to keep this between us? Perhaps this could drive you business.

Privacy of private communication is sacred to me (excepting scammers, threats etc.) Thus, I would not do so without express agreement. Whereupon, I will start writing a didactic orgasm for you. Perfectly fine by me, you have my enthusiastic permission to reveal all of our shared secrets
Welcome thus to Ciphersex 101.

ETH is amazing and extremely functional, but nothing will replace BTC as king crypto in the short to medium term for multiple reasons. ETH is also far more centralized both technically and ideologically.
To that, I will simply quote myself from recently: This needs to be in a stickied FAQ somewhere: Just my 2 Satoshis: I've disliked Ethereum ever since their one Unique Selling Point ("code is law" for smart contracts) got thrown out of the window after The DAO failed so hard they had to abandon their core principles and hardfork to get their money back. It proved that smart contracts are worthless if you don't understand them, which makes them worthless for almost everybody. In the case of The DAO, even the developers didn't understand the code, the only person who understood it was called "the attacker". Ironic!
In the abstract, what the so-called “attacker” did was no different than a smart lawyer finding a gaping loophole in a contract. It was fully authorized use of a computer network in the exact manner which the network was declared to be intended. Per the legally binding terms of the DAO: “The terms of The DAO Creation are set forth in the smart contract code existing on the Ethereum blockchain at 0xbb9bc244d798123fde783fcc1c72d3bb8c189413. Nothing in this explanation of terms or in any other document or communication may modify or add any additional obligations or guarantees beyond those set forth in The DAO’s code.”Following those terms was not an “attack”. It most certainly was not a “theft”! It was only the fully foreseeable result of declaring that “code is law”, and then writing low-quality code-law with unknown, unverifiable properties. If you dare do that because you want a flashy media event with bucketloads of investor money suddenly pouring in, then prepare yourself for your doom by meditating on the cosmic (and comic) inevitable consequences: This is why I am so enamoured with the Bitcoin Simplicity concept, which I linked to above. It is serious research with the goal of producing mathematically provable contracts. We need advanced smart contracts which have no code-loopholes, just as verifiably as “2+2=4” has no loopholes. For in Bitcoin, code truly is law. In Bitcoin, there shall never be the disgusting sham of a so-called “ irregular state change”. In Bitcoin, there is no central authority with the ability to mandate such a thing! (I do think that centrally managed pretenders with mathematically unverifiable “smart” contracts are fully suitable for use as toys, such as CryptoKitties.)
It'd be fun to shoot Vitalik in the head and watch the price of ETH.
Ethereum is centralized, as demonstrated by Vitalik’s ability to command that “irregular state change”. Among other things, I believe that is called a “single point of failure”. |

Spot on about all the ICOs and other scams. A “very deep and painful cleansing” may well be an understatement as to what will necessarily happen there. But how much will that affect Bitcoin? It seems to me that Bitcoin leads the market with all the “weeply site and a shitty whitepaper” stuff riding on its coattails; how much could collapse of the latter affect the former?
Usually the on-ramp to an ICO is BTC or ETH. To buy AliaCoin, you have to buy ETH, and sometimes to buy ETH, you have to buy BTC. The ICO thing is going to hit people hard. Sure, the BTC bubble may not have such a terrible crash - in fact, we may have already seen it happen - but it is undeniable that people are taking these gains for granted. "HODL", "BTFD", etc.: online sentiment shows that almost everyone thinks that BTC will always have an upward trajectory, and such optimism inevitably indicates a coming crash. It would be interesting to know quantitatively what proportion of the fiat-to-BTC exchange is only an “onramp” to alts. I expect the proportion to be relatively small, as indicated by relative market caps. Also, I have no idea what the three-way price interactions would be across a fiat-BTC-alt transaction. As for taking these gains for granted, well—there must be a limit somewhere, but I myself think we’re far from it. Limited BTC supply, geometrically increasing demand, etc. I do not think there is or has yet been a Bitcoin bubble. I do think there are and will continue to be severe corrections along the way, as all the idiots who believe they can get rick quick buying BTC get sheared and shaken out of the market. Small, temporally limited bubbles, if you will. Long-term increase in demand then picks the price back up. Could be wrong entirely tho because bitcoin tends to defy all logic anyway
No, Alia: The only thing here which defies logic is how thrilling I suddenly find it to be holding a discussion amidst one of these torrential speculative threads in Bitcoin Discussion. |

This is wholly my opinion (not based in any truth or fact whatsoever, nobody can predict the markets) - but I opine that the market is still in need of a very deep and painful cleansing. ICOs are still earning many millions with a weebly site and a shitty whitepaper. These gains came too easily, they have to be lost. I believe that the price of BTC will go sub-$6k at least once in 2018, if not much lower, before it proceeds upwards. $20k is not out of the question, but beware.

N.b. that I’m not a speculator. I sometimes watch the market, but I don’t try to play it, nor do I have any desire to. I actually have only a vague idea of what the BTC/fiat exchange rates may be at this particular moment; I usually look up the pertinent rate when I need to buy something denominated in fiat, and I don’t shop very much. Thus, my opinion here may not be adequately well-informed. |
