A simple tool for generating and filtering vanity GPG keys (a.k.a. A OpenPGP key fingerprint collision tool), c0nCurr3nt1Y.

Currently(v0.3), VanityGPG offers two sets of backends, Sequoia-OpenPGP and rPGP. If you have libclang available in your system, the default sequoia backend is recommend.

Install dependencies (assuming you are using Ubuntu, bruh) for the sequoia backend:

apt install git rustc cargo clang make pkg-config nettle-dev libssl-dev capnproto libsqlite3-dev

Install VanityGPG with cargo:

cargo install vanity_gpg

If your system does not offer libclang, there is also a pure rust rPGP backend available:

cargo install vanity_gpg --no-default-features --features rpgp

If the rPGP backend is used, it's not recommended to use the key generated by it as your main key. It uses a PRNG for generating random numbers, which is considered (kind of) insecure.

With the following parameters:

./vanity_gpg -c Ed25519 -jX -u "Kay Lin <[email protected]>" -p "(8B){5,20}$|(B8){5,20}$|(EB){5,20}$|(BE){5,20}$|(EF){5,20}$|(FE){5,20}$|A{10,40}$|B{10,40}$|C{10,40}$|D{10,40}$|E{10,40}$|F{10,40}$|1{10,40}$|2{10,40}$|3{10,40}$|4{10,40}$|5{10,40}$|6{10,40}$|7{10,40}$|8{10,40}$|9{10,40}$|0{10,40}$|1145141919810$"

Sequoia-OpenPGP and the rPGP teams for their awesome works.

@nwalfield for the extremely helpful tips that improves VanityGPG's performance for several orders of magnitude (#2).

vanity_gpg 0.3.0
A simple tool for generating and filtering vanity GPG keys, c0nCurr3nt1Y

USAGE:
    vanity_gpg [FLAGS] [OPTIONS] --pattern <pattern>

FLAGS:
    -d, --dry-run    Dry run (does not save matched keys)
    -h, --help       Prints help information
    -v, --verbose    Verbose level
    -V, --version    Prints version information

OPTIONS:
    -c, --cipher-suite <cipher-suite>
            Cipher suite [default: Ed25519] [possible values: Ed25519, RSA2048, RSA3072, RSA4096,
            NISTP256, NISTP384, NISTP521]

    -j, --jobs <jobs>                    Number of threads [default: 8]
    -p, --pattern <pattern>              Regex pattern for matching fingerprints
    -u, --user-id <user-id>              OpenPGP compatible user ID

Notes:

• There will be an extra thread spawned for displaying summary.
• It's recommended to use multiple rules with regex for maximum efficiency.

On AArch64 machines, you may have to disable the "asm" feature for sha-1 before compiling.
