Installation

make
make install
make uninstall

Usage

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!
