fernet-cli

Now, the power of Fernet is available from the shell!

tl;dr

“maher@og-kush:~$ gem install fernet-cli Fetching: fernet-cli-0.4.gem (100%) Successfully installed fernet-cli-0.4 Parsing documentation for fernet-cli-0.4 Installing ri documentation for fernet-cli-0.4 Done installing documentation for fernet-cli after 0 seconds 1 gem installed tmaher@og-kush:~$ fernet-encrypt –help Usage: fernet-encrypt [-p | -k ]

“

And there’s a corresponding fernet-decrypt too. The key should be a base64-encoded blob of 256-bits. If you’d rather not write it out to a file or get promted for it, you can save it to shell environment variable FERNET_CLI_KEY.

For fernet-encrypt, the infile is plaintext and the outfile is ciphertext. For fernet-decrypt, the infile is ciphertext and the outfile is plaintext.
