Description:

Zend\Crypt provides support of some cryptographic tools. The available
features are:

- encrypt-then-authenticate using symmetric ciphers (the
authentication step is provided using HMAC)
- encrypt/decrypt using symmetric and public key algorithm (e.g. RSA
algorithm)
- generate digital sign using public key algorithm (e.g. RSA
algorithm)
- key exchange using the Diffie-Hellman method
- Key derivation function (e.g. using PBKDF2 algorithm)
- Secure password hash (e.g. using Bcrypt algorithm)
- generate Hash values
- generate HMAC values

The main scope of this component is to offer an easy and secure way to
protect and authenticate sensitive data in PHP. Because the use of
cryptography is not so easy we recommend to use the Zend\Crypt
component only if you have a minimum background on this topic.
