Method Summary
-
decrypt() public static deprecated
Decrypt a value using AES-256.
-
encrypt() public static deprecated
Encrypt a value using AES-256.
-
rijndael() public static deprecated
Encrypts/Decrypts a text using the given key using rijndael method.
Method Detail
decrypt() ¶ public static
decrypt(string $cipher, string $key): stringDecrypt a value using AES-256.
Parameters
-
string$cipher The ciphertext to decrypt.
-
string$key The 256 bit/32 byte key to use as a cipher key.
Returns
stringThrows
InvalidArgumentExceptionOn invalid data or key.
encrypt() ¶ public static
encrypt(string $plain, string $key): stringEncrypt a value using AES-256.
Caveat You cannot properly encrypt/decrypt data with trailing null bytes. Any trailing null bytes will be removed on decryption due to how PHP pads messages with nulls prior to encryption.
Parameters
-
string$plain The value to encrypt.
-
string$key The 256 bit/32 byte key to use as a cipher key.
Returns
stringThrows
InvalidArgumentExceptionOn invalid data or key.
rijndael() ¶ public static
rijndael(string $text, string $key, string $operation): stringEncrypts/Decrypts a text using the given key using rijndael method.
Parameters
-
string$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
Returns
stringThrows
LogicExceptionWhen there are errors.
