OpenSSL implementation of crypto features for Cake\Utility\Security
OpenSSL should be favored over mcrypt as it is actively maintained and more widely available.
This class is not intended to be used directly and should only be used in the context of Cake\Utility\Security.
rijndael(string $text, string $key, string $operation) : void
Not implemented
| string | $text | Encrypted string to decrypt, normal string to encrypt |
| string | $key | Key to use as the encryption key for encrypted data. |
| string | $operation | Operation to perform, encrypt or decrypt |
Rijndael compatibility does not exist with Openssl.
encrypt(string $plain, string $key) : string
Encrypt a value using AES-256.
Caveat You cannot properly encrypt/decrypt data with trailing null bytes. Any trailing null bytes will be removed on decryption due to how PHP pads messages with nulls prior to encryption.
| string | $plain | The value to encrypt. |
| string | $key | The 256 bit/32 byte key to use as a cipher key. |
On invalid data or key.
Encrypted data.
decrypt(string $cipher, string $key) : string
Decrypt a value using AES-256.
| string | $cipher | The ciphertext to decrypt. |
| string | $key | The 256 bit/32 byte key to use as a cipher key. |
On invalid data or key.
Decrypted data. Any trailing null bytes will be removed.
