goose

just like https://git.sr.ht/~sircmpwn/noseplumbs, but in go.
Cross-platform, has no dependencies except of golang.org/x/crypto/*.

Uses Ed25519 for signatures and curve25519/XSalsa20/Poly1305 for encryption/decryption.

Installation

make
make install
make uninstall

Generate secret key:

goose genkey -e > enc.priv.key
goose genkey -s > sign.priv.key

Generate public key:

goose pubkey < enc.priv.key > enc.pub.key
goose pubkey < sign.priv.key > sign.pub.key

Encrypt input:

goose encrypt enc.pub.key < cleartext.txt > ciphertext.bin

Decrypt input:

goose decrypt enc.priv.key < ciphertext.bin > cleartext.txt

Sign input:

goose sign sign.priv.key < cleartext.txt > cleartext.sig

Verify input signature:

goose verify sign.pub.key cleartext.sig < cleartext.txt

Enjoy!
