Describe the bug
Trying to use a triple-length key I get the error:
Invalid key length: 24 bytes

DES uses a key length of 8 bytes (64 bits).
Triple DES uses a key length of 24 bytes (192 bits).

To Reproduce
Link to recipe

Expected behaviour
No error, and an attempt to decrypt/encrypt the input

Additional context
I looked at the code and it only checks for length 8 bytes

if (key.length !== 8) {
            throw new OperationError(`Invalid key length: ${key.length} bytes

DES uses a key length of 8 bytes (64 bits).
Triple DES uses a key length of 24 bytes (192 bits).`);
}
