- When building from the repo without installing, set `FUN_LIB_DIR` to the local `./lib` directory so examples and the REPL can locate the stdlib.
- For a broader project overview and quickstart, see the repository root [README.md](../README.md).
- Crypto example: if built with `-DFUN_WITH_OPENSSL=ON`, try `examples/crypto/openssl_md5.fun` to compute MD5 using OpenSSL.

Tip: you can run specific examples directly too:
```
FUN_LIB_DIR="$(pwd)/lib" fun examples/crypto/aes256.fun

```
## Example categories
Browse the `examples/` tree for areas of interest:
- crypto — crypto demonstrations (e.g., AES)
- crypto — crypto demonstrations (e.g., OpenSSL MD5 helper; requires build with `-DFUN_WITH_OPENSSL=ON`)
- blocking / interactive — I/O or user-interactive patterns
- error / broken — negative tests and error showcases
- math — numeric operations

- OP_CURL_POST: HTTP POST; pops body:string, url:string; pushes response:string or Nil.
- OP_CURL_DOWNLOAD: Download URL to file; pops path:string, url:string; pushes 1/0.
## OpenSSL (optional)
- OP_OPENSSL_MD5: Compute MD5 digest and return lowercase hex string; pops data:string; pushes md5:string.
- Requires building with `-DFUN_WITH_OPENSSL=ON`. When disabled, this opcode still exists but returns an empty string to match other optional extensions’ fallback behavior.
