- Purpose: provide small crypto helpers backed by OpenSSL. Includes md5, sha256, sha512, ripemd160 helpers.
- Homepage: https://www.openssl.org/
Build notes:
## Build notes:
- Requires system OpenSSL development headers and libraries.
- On OpenSSL 3.x, legacy MD5_* APIs are deprecated; you may see warnings during build.
Provided helper/opcodes:
## Provided helper/opcodes:
- Function: openssl_md5(data:string) -> string (lowercase hex). Falls back to empty string when the extension is disabled, mirroring other optional modules.
- Function: openssl_sha256(data:string) -> string (lowercase hex).
- Function: openssl_sha512(data:string) -> string (lowercase hex).
- Function: openssl_ripemd160(data:string) -> string (lowercase hex). Note: On OpenSSL 3.x this may require the legacy provider; if the digest is unavailable, the helper returns an empty string.
- Opcodes: OP_OPENSSL_MD5, OP_OPENSSL_SHA256, OP_OPENSSL_SHA512, OP_OPENSSL_RIPEMD160 (internal mappings for the functions above).

## Notes:
Notes:
- The OpenSSL 3.x provider configuration on your system determines availability of RIPEMD‑160. If the legacy provider is not enabled, openssl_ripemd160() will return an empty string.
