A command line tool for playing with the NaCl cryptography library. This is a toy, so please don't feed it any important data.
Symmetric encryption example:
$ plaintext="Release the hounds."
$ key=$(./clinacl.py secretgen)
$ echo $key

$ nonce="deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef"
$ echo $nonce
deadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef
$ ciphertext=$(echo $plaintext | ./clinacl.py encrypt $key --nonce $nonce)
$ echo $ciphertext

$ echo $ciphertext | ./clinacl.py decrypt $key
Release the hounds.
Public key signature example:
$ signingkey=$(./clinacl.py signinggen)
$ echo $signingkey

$ echo $verifykey

$ message="The truth, the whole truth, and nothing but the truth."
$ echo message | ./clinacl.py sign $signingkey

$ echo $message | ./clinacl.py sign $signingkey | ./clinacl.py verify $verifykey
The truth, the whole truth, and nothing but the truth.
