----

-
-- CMake option: FUN_WITH_OPENSSL=ON
-- Purpose: provide small crypto helpers backed by OpenSSL. Includes md5, sha256, sha512, ripemd160 helpers.
-- Homepage: [https://www.openssl.org/](https://www.openssl.org/){:class="ext"}
-
-## 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:
-
-- 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).
-
-## Quickstart:
-
-- Configure: cmake -S . -B build -DFUN_WITH_OPENSSL=ON
-- Build: cmake --build build --target fun
-- Run examples:
-  - ./build/fun examples/crypto/openssl_md5.fun
-  - ./build/fun examples/crypto/openssl_sha256.fun
-  - ./build/fun examples/crypto/openssl_sha512.fun
-  - ./build/fun examples/crypto/openssl_ripemd160.fun
-

-- ripemd160(abc) = 8eb208f7e05d987a9b044a8e98c6b087f15a0bfc
-- ripemd160("") = 9c1185a5c5e9fc54612808977ee8f548b2258d31
-
-## 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.
