For the record... your narcissist-cli.exe.gpg "signature" seems to be more of an encrypted GPG archive than a signature... when I attempted to verify the Windows Build download using Kleopatra and the public key linked from your bitcointalk sig, I was getting an "Decryption Failed - No data"... it wasn't until I actually used the commandline, removed the .exe and just used "gpg narcissit-cli.exi.gpg" before it worked. Huh

Granted, I'm not terribly familiar with GPG... but usually I just download the .sig or .asc file along with .zip or .exe or whatever and use the "Verify" option.

Apologies, I forgot to use a detached signature when signing the Windows build. I have now attached the proper one to the GitHub release and everything should work now

Code:

$ wget https://github.com/matthewincognito/narcissist/releases/download/v0.1.0/narcissist-cli.exe https://github.com/matthewincognito/narcissist/releases/download/v0.1.0/narcissist-cli.exe.sig
$ gpg --recv-keys 0xBC2BB1D36104939BE924AA51A09E643F541C0FC5
$ gpg --verify narcissist-cli.exe.sig 
gpg: assuming signed data in 'narcissist-cli.exe'
gpg: Signature made Sun 01 Apr 2018 08:48:56 BST
gpg:                using RSA key BC2BB1D36104939BE924AA51A09E643F541C0FC5
gpg: Good signature from "Matthew Incognito " [ultimate]

narcissist
easy peasy vanity addresses

Notes
I just wrote this for fun, don't trust it with your Bitcoin life savings. If you find a way to break it, I'd love to know how

Also thank you luke-jr for the base58 encoding code, Pieter Wuille for the bech32 address encoding code, and nullius for creating segvan.

Current Features

Split key functionality so that untrusted parties can mine an address for you.
Support for bech32 (segwit) addresses
Easy to use
Cross platform

Planned Features

Multi-threading
Benchmarking/statistics
Vanity address mining pool
P2SH-P2WKH addresses
Regex matching

Usage

Code:

Allowed options:
  --help                                    print this message
  -G [ --generate-keypair ]                 generate a keypair for split-key usage
  -B [ --brute-address ]                    address generation mode
  -C [ --combine-split-key ]                split-key combination mode
  -p [ --brute-address-prefix ] arg         prefix for bruteforcing
  -P [ --split-public-key ] arg             public key, for split-key usage
  -i [ --split-private-key ] arg            private key, for split-key usage
  -T [ --address-type ] arg (=bech32-p2wkh) p2pkh or bech32-p2wkh

Examples
Generate a bech32 address on your own

Code:

$ ./narcissist-cli -B -p bc1pppp

    WIF: L68rHUEpdUU1HgUVVEpShqGS7QhJqe8ap8G4D7vFxHEeo7WYYffZ

Generate a P2PKH address on your own

Code:

$ ./narcissist-cli -B -p 123 -T p2pkh
Private: 2B48614E3CF6BFD713E84573B3420BC10B2A2B0CE9C17CEF003D1D1ADDD9DF52

Generate a bech32 address with somebody else

Code:

$ # generate a keypair for yourself
$ ./narcissist-cli -G
 Public: 03C3172451E46BDED75697393A34B1942B15A4DBD34F3FCBA4D4583B521DF2BA82

$ # share the *public* key with somebody else and they can mine the address for you
$ ./narcissist-cli -B -p bc1ppppp -P 03C3172451E46BDED75697393A34B1942B15A4DBD34F3FCBA4D4583B521DF2BA82

Address: bc1ppppp3mcw4dx7s5d8qsrn4rlwv60p44jegtqztj

$ # using the tweak value found on the miner's computer, combine it with the private key you generated at the start
$ ./narcissist-cli -C -i 6EE8D1E4959DF280DAF6D3D3833B5200F0738D726ACC24C3D611993D5E57F24B -P D4A7A845C3883D6849091217D285A7B3FF8866E1616F2A6A1739DA98FB2C5114

Post some public keys and short prefixes here, maybe somebody will mine them for you. Wink
