What is this?

This is a simple tool to encrypt and decrypt your file. In encrypting, the tool needs a passphrase (password) as input and a salt file (which would be auto-generated by the tool). Your passphrase would be hashed by scrypt. To encrypt your file, the tool uses the AES-256 encryption algoritm.

Usage

1. Encrypt a file

   $ ./let-us-lock encrypt -f {your path file} -o {your output file name}
   

2. Decrypt a file

   $ ./let-us-lock decrypt -f {your path file} -o {your output file name}
