Detailed Description

Implements OP_OPENSSL_MD5 to compute an MD5 hash in hexadecimal.

Behavior:

• Pops one value from the VM stack and converts it to a byte sequence by obtaining its string representation using value_to_string_alloc().
• Computes the MD5 digest of the resulting bytes via fun_openssl_md5_hex() and pushes the lowercase hexadecimal string back onto the stack.
• On allocation or hashing failure, pushes an empty string ("").

Notes:

• Non-string inputs are accepted; they are stringified first.
• This snippet is included by vm.c and executed when OP_OPENSSL_MD5 is dispatched.

Errors:

• This opcode does not terminate the VM. Failures result in an empty string being pushed.
