    METHOD_AES_256_CBC 
    'aes-256-cbc'

Method Summary

  • decrypt() public static

    Decrypt a value using AES-256.

  • encrypt() public static

    Encrypt a value using AES-256.

Method Detail

decrypt() public static

decrypt(string $cipher, string $key): string

Decrypt a value using AES-256.

Parameters

string $cipher

The ciphertext to decrypt.

string $key

The 256 bit/32 byte key to use as a cipher key.

Returns

string

Throws

InvalidArgumentException
On invalid data or key.

encrypt() public static

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.
