Bitcoin Signature and Checking for PC
Fast Sign Verify Copyright (C) 2014 Antoine FERRON This is a software for PC which is focused on ECDSA Bitcoin signature. It can check or sign with a wallet. Official thread, support: bitcointalk.org/index.php?topic=623085 Install : Windows : Zip with binaries provided in Releases. Linux or MacOSX : Needs Python 2.7.x and WxPython >= 2.8 Use: For signing: Enter a message and a private key (WIF - base58chk). You can chose determinstic signing or standard random signature. Signature will appear in "signature" field after clicking on "Sign". You can copy in clipboard the signature alone or the full signature with "Copy All". This will fill the clipboard with "PGP style" signature that you can copy directly in your email, forum message, etc... For now, I don't recommend signing using Windows without deterministic. For checking: Enter the message, a public key (base58chk) and a signature (base64). You can also enter a full message "PGP like" in message field (no need to fill Address nor Signature field.) It automagically detects the format between these two: 1) Simple "Input.io" style ---- MESSAGE HEADER ---- message signed is here ---- SIG HEADER ---- 1AddressBitcoin Signature= ---- END FOOTER ---- 2) "Qt1.0" style, Multibit ---- MESSAGE HEADER ---- message signed is here ---- SIG HEADER ---- Version: Info Address: 1AddressBitcoin Signature= ---- END FOOTER ---- If you have any other format, you have to enter in the dedicated fields. For example when message is signed with Electrum or official client, most of the time you have to enter in 3 fields (message, address and signature). Future Improvements: Private key import wizard (wallet.dat, DER, ...) Signature export and import options (format, PKCS,...) Private key, address, options saving BTChip integration (signing with USB keycard) Licence related: Some portions based on : "python-ecdsa" Copyright (C) 2010 Brian Warner (MIT Licence) "Simple Python EC and ECDSA" Copyright (C) 2005 P.
