How much would 1TriggerX cost for case sensitive and non case sensitive?

1TriggerX w/o case would cost you 0.2337 BTC (takes a few weeks depending on luck) - diff: 23,349,487,483,220
1TriggerX with exact case would take a few years. The estimated price would be 72.5166 BTC, but its not something I would want to do - diff: 2,988,734,397,852,220

1Trigger w/o case would cost you 0.0084 BTC

Edit: To explain why its different from 1abcdefgh: 1T or 1t at the beginning is more difficult than 1[a,A] or even 1[k,K], the "i" has no upper case symbol in base58 so its essentially with case which does the rest. I added an example for that case. "q" seems to be the letter where it starts.

Is this vanity address generator safe? I heard before the service like this make your private key held by third party which can take your coin anytime.

Correct me if i am wrong.
The OP will only have access to 1/2 of the private key, and as a result will not be able to steal any BTC that you store in any vanity address generated by the OP.

If you bothered to read the instructions in the 1st post then you would see that you 1st create a keypair, give the OP the public key, then combine the private key given to you by the OP with the private key associated with the public key you previously gave the OP to calculate the private key of your vanity address. You should notice that at no point does the OP ever have the entire private key to your address.

Good question. Its safe because I never have your final private key.
You generate your private key and send me the public key.
I generate a partial private key where the combined public keys result in your vanity address.
You combine both private keys into a new private key only you know to get the finished vanity address. Due to the way private and public keys work this is safe as long as bitcoin itself is safe.
Knowing the partial private key gives me no advantage when trying to find the exact private key for your address. Well, almost no advantage. Instead of checking 2256 possible private keys I only have to check (2256)-1 private keys. So I have a few fractions of a picosecond advantage on a race that lasts till the sun burns out.

As the private key is not generated on my machine I can "prove" that I dont store it, yes. The private key I have has a different address, only in combination with your part will it result in the address requested.

I cant prove the underlying mathematics of combined private keys for eliptic curves, no. My math is not good enough for that, its just good enough to understand why its secure. If you are interested I suggest you read this[1] post. It has some minor mistakes regarding the way the addition works for eliptic curves as was pointed out here[2] which links this[3] document (pg. 12) as source. For a simple, but correct introduction to eliptic curves in general I suggest this[4] presentation by djb. He and Tanja Lange explain it with clocks which is IMHO a very good way to understand the fundamental concept. To transfer this here. Both keys combined spin around the clock and end up in a spot I can not predict from only my part.

Do you have the ability to have vanitygen continue checking for addresses until multiple have been found of either the same criteria or of different criteria?

For example can you tell it to continue looking until it has found 3x of 1abcdefgh and/or to continue looking until it has found 1abcdefgh, 1ijklmnop and 1qrstuv?

Only for the same pubkey or without providing a pubkey and I cant limit it to a certain number or strike off results. There are basically two flags that help, but are not as flexible as one would hope.

#1 is -k it ensures vanitygen keeps going after finding a key. It does not stop a certain number though, it has to be cancled manually.

#2 is -f pattern.txt it allows you to store any amount of prefixes in a file and it will search for all of them at once. If it finds any it will stop (or not with -k). It will keep finding easier (low diff) results though and not strike them off the list.

E.g. this is the file I made for referee

Code:
1Referee
1referee
1R3feree
1r3feree
1Ref3ree
1ref3ree
1Refer3e
1refer3e
1Refere3
1refere3
1R3f3ree
1r3f3ree
1R3fer3e
1r3fer3e
1R3fere3
1r3fere3
1R3f3r3e
1r3f3r3e
1R3f3re3
1r3f3re3

There is also -r which allows to search for regular expressions (e.g. the above would be 1[R,r][e,3]f[e,3]r[e,3]{2}). Thats however not working with the GPU.
Can you give me a quote for the first 20 addresses that is found from the following list (case insensitive) (a single public key would be provided)
Code:
1panthers
1camnewton
1superman
1elevenn0
1superbowl
1suprbowl
1panthers1
1panthers59
1nolosses
1lukeeeee
1lukeee59
1tochdown
1winners0
1runtable

'0' is not a valid char, so those are ignored, I can replace them with 'o' instead.

Vanitygen also showed this error:

Code:
Prefix '1panthers1' ignored, overlaps '1panthers'
Prefix '1panthers59' ignored, overlaps '1panthers'

If I take 1panthers out and replace the 0 with o, the prefixes without exact case have a combined difficulty of 229,244,582,148 (12 prefixes) which would cost you 0.0026 BTC for the first found.



hi shorena how much it cost for addy 1HimeaBTC, 1Himeabtc or 1Himea

I made a little table for you.

Code:
1HimeaBTC  - exact case   - 0.4470 BTC
1HimeaBTC  - without case - 0.0078 BTC
1Himeabtc  - exact case   - 0.4470 BTC
1Himeabtc  - without case - 0.0078 BTC
any of two - exact case   - 0.2312 BTC
1Himea     - exact case   - 0.0001 BTC
1Himea     - without case - donation
