Cloak (beta)
A simple command line passphrase based file encryption tool.
Cloak is a simple command line passphrase based file encryption tool, its similar to openssl enc, but it uses scrypt for passphrase key derivation and nacl box for encryption.
This tool is still a WIP.

TODO
- flag "-overwrite" "-o" overwrites original file
- flag "-r" encrypts all files in dir
- efficitenly read large files using line by line chans
- encrypt using msgpack format ?
- key splitting using shamir
- human readable passphrase generator ?
