sym 2.1.1

Sym is a versatile command line utility and a library, that streamlines access to a symmetric encryption offered by OpenSSL library. Use its rich CLI interface, or the Ruby API to generate a key used for both encryption and decryption. You can additionally password protect the key, and optionally store the key in the named OS-X keychain. Use the key to reliably encrypt, decrypt and re-encrypt your application secrets. Use the -t CLI switch to open an encrypted file in an editor of your choice. Sym uses a symmetric aes-256-cbc cipher with a private key and an IV vector.
