scrambler 0.0.1

scrambler

A tool for encrypting and decrypting entire directories on-the-fly.

scrambler uses a block cipher and passphrase to encrypt and decrypt files in-place, as a means for quickly securing content without having to move things and/or create archives. scrambler appends a .enc extension to encrypted files, so it can use context clues to determine whether you want to perform encryption or decryption.

As of writing, this application uses an AES-256 block cipher, with a passphrase that's hashed by SHA-256.
