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. |
