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.
## Usage
```shell
# Show help information.
scrambler -h
