/**
|
|
* @file sha512.c
|
|
* @brief Implements OP_OPENSSL_SHA512 to compute a SHA-512 hash in hex.
|
|
*
|
|
* Behavior:
|
|
* - Pops one value from the VM stack and converts it to bytes by first
|
|
* turning it into a string with value_to_string_alloc().
|
|
* - Computes the SHA-512 digest via fun_openssl_sha512_hex() and pushes the
|
|
* lowercase hexadecimal string back on the stack.
|
|
* - On allocation or hashing failure, pushes an empty string ("").
|
|
*
|
|
* Notes:
|
|
* - Non-string inputs are accepted and stringified first.
|
|
* - This file is included by vm.c and handles OP_OPENSSL_SHA512.
|
|
*
|
|
* Errors:
|
|
* - Does not abort the VM; failures return an empty string.
