NaClSecretBox

NaClSecretBox is a utility to encrypt and decrypt multiple files using the same key but a different nonce.

Installation:

go get github.com/marcopeereboom/naclsbox

Encryption example:

$ naclsbox -e myfile 
encryption key: 0c4d1b5840347b698b92e7c33a87f52e721616fede4c82ce22a0783001cc6c92

This generated a file called myfile.sbox which contains the encrypted data.

Take note of the encryption key. It can not be recovered.

In order to reverse the process must provide the key and encrypted blob filename.

Decryption example:

$ naclsbox -d -k 0c4d1b5840347b698b92e7c33a87f52e721616fede4c82ce22a0783001cc6c92 myfile.sbox

This generated a file called myfile.sbox.decrypted which should be an identical copy of myfile.

Verification:

$ shasum myfile
f951b101989b2c3b7471710b4e78fc4dbdfa0ca6  myfile
$ shasum myfile.sbox.decrypted 
f951b101989b2c3b7471710b4e78fc4dbdfa0ca6  myfile.sbox.decrypted
