# pgp-suffix-finder Brute force PGP key ID suffixes of arbitrary length. ## Warning! This tool can brute force any (short) PGP key suffix, use it for good; e.g. creating vanity key IDs. Don't use it to generate collisions and annoy other PGP users. Thanks ## Requirements A recent Go version will give you the SIMD variant of the SHA1 algorithm. You need GnuPG available as `gpg`. Versions 1.4.20 & 2.0.30 are tested and work properly, 2.1.18 doesn't work. ## Building Prepare a Go environment if you haven't done so already, for more information refer to https://golang.org/doc/install Install using `go get`: $ go get git.maze.io/maze/pgp-suffix-finder $ go build git.maze.io/maze/pgp-suffix-finder Otherwise, clone into `$GOPATH`: $ mkdir -p $GOPATH/git.maze.io/maze $ git clone https://git.maze.io/maze/pgp-suffix-finder \ $GOPATH/git.maze.io/maze/pgp-suffix-finder $ go build git.maze.io/maze/pgp-suffix-finder ## References ### OpenPGP specification https://tools.ietf.org/html/rfc4880 ### Short key IDs are bad news http://www.asheesh.org/note/debian/short-key-ids-are-bad-news.html ### Stop it with those short PGP key IDs! http://gwolf.org/node/4070
