 **AES128Encrypt**: ciphers the provided plaintext using AES128 in CBC mode, padding the input using PKCS#7.
 
 **AND**: performs the bitwise AND of `lhs` and `rhs`. `bit_size` must be the same for both inputs.

-#### Directive

-This opcode is a specialization of Brillig opcode. Instead of having some generic
-assembly code like Brillig, a directive has a hardcoded name which tells the
-solver which computation to do: with Brillig, the computation refers to the
-compiled bytecode of an unconstrained Noir function, but with a directive, the
-computation is hardcoded inside the compiler.
