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:
bash
apt install git rustc cargo clang make pkg-config nettle-dev libssl-dev capnproto libsqlite3-dev
Install VanityGPG with cargo:
bash
cargo install vanity_gpg
If your system does not offer libclang, there is also a pure rust rPGP backend available:
bash
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:
bash
./vanity_gpg -c Ed25519 -jX -u "Kay Lin <i@v2bv.net>" -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
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
-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.
