دوستان کسی امتحان کرده توی این اختلالات اینترنت اخیر آیا پرتوکلهای بیت کوین هم فیلتر شدن یا خیر؟
جایی خودنده بودم فیلترینگ بخشیش به روش پَکِت اینسپِکشِن  هست و هر پروتوکلی رو که نتونه تشخیص بده فیلتر میکنه...
پروتوکل بیت کوین هم احتمالا جز پروتوکلهای وایت‌لیست نیست پس احتمالا فیلتر بشه

I think encrypting message with private key is fundamental operation of signing files.


Anyways as I searched, the Kleopatra (https://www.openpgp.org/software/kleopatra/) is good GUI tool for asymmetric encryption, also supports ECDSA NIST P-256 (not sure if it is secp256). but still it do not support encrypting with private key.

Is there any secure GUI tool which i can use to Encrypt/Decrypt and sign message or files with my ECDSA Secp256k1 private key?
GUI could be binary file, or local HTML file.

Think of Alice had become a cyberpunk . She has a private key:


and public key


she gives her public key to Bob, is there any simple GUI tool for Alice to sign a file and sen then signature to Bob by email?
Bob also needs same tool to simply verify the file signature with Alice pub key.

or maybe she want to simply encrypt a plane text message with her private key and send it to bob by email, than bob decrypt it with Alice pub key.

is there any simple GUI (binary or better HTML) tool for this? Also encrypt, decrypt capability would be appreciated.
Thanks

در مورد ایده و پیاده سازی هم چیز جالبی گفتی. ایده زیاده ولی امکان پیاده سازیش نیست
خوب این رو در نظر بگیر که پیاده سازی ممکنه چیز ساده ای نباشه. مثلا ایده ساخت یک وبسایت ممکنه ساده باشه ولی در عمل با وب سرور اپاچی و پی‌اچ‌پی و هزار تا چیز دیگه ممکنه روبرو بشی. باقی ایده ها هم شبیه به همین.
اگر ایده داری تازه اول راهی

In short, there is no way.
if you have a source code and have a binary file, (as far as i understand) then there is no way to ensure the code and binary are matched, unless you compile it yourself.

ما توی این کشورمون این همه آدم و شرکت داریم که روی بیتکوین میلیاردی سرمایه گذاری کردن ولی حتی یک دونه نود بیت کوین هم توی ایران فعال نیست (حالا شاید یدونه باشه ولی بعید میدپونم دوتا بشه)
این یعنی ملت فقط استفاده کننده هستن و فقط سرمایه وارد میکنن. ولی توی قسمت فنی و نگهداری از شبکه کمک نمیکنن. حس چندان خوبی نسبت به این قضیه ندارم. نظر شما چیه دوستان؟

Didn't test it yet. not sure if it support

yes,  I finally ended up writing assest and first few characters of each address on the same paper. also hex is not easy to read and write, with a single mistake all are gone wrong... this is some time saw the mnemonic, and HD wallet, but i thought it is only for bitcoin. which was not true and it can be used for many coins...
Writing down mnemonic phrase is much simpler than writing down hex numbers. But on the other side, anyone on earth can identify a paper with mnemonic phrase on that as crypto key, but a hex writing is less identify-able as private key

Anyways the mnemonic and BIP44 etc. is how some bitcoiners here do keep their asset, so i definitely rather to test it.

Thanks for replies...

That's the point. Reusing the pvt key for long time hold.
The process of making a (cold - secure) private key is a little hard to me, use an fresh offline PC to generate random 32 byte pvt key, then write the 64 character HEX on the paper in order to do not use a printer then test it on testnet and finally there is a tested and functional pvt key. then generate the pub key and keep it on my online PC. Sounds like masochism right?

Also, me wasn't able to find good tools for generating wallets for LTC and DOGE, so rather to make a BTC paper wallet, then use its address to generate LTC and DOGE wallets. Note that i'm (probably) not like one of the guys here who use bitcoin core and are sync with the network. so will use light tools like coinb.in which supports BTC LTC DOGE.

Yes, the tools me using do support hex pvt key. so do not use WIF at all.

is it a good idea to use same private key for keeping Bitcoin and Litecoin and Dodgecoin?
I do not mean seed phrase, but a raw 32 byte random private key.
Private key will give us a public key, that can be used to generate address for BTC, LTC and Dodgecoin. I dont think there be any problem with this, what you think?

For example which crypto project you do mean? can you please name one?

AFAIK the bitcoin uses 32 byte private key, but this private key seems to be way more that 32 bytes, so I think it does not belong to a bitcoin address.

The store format seems to be PKCS8.
