Here's what changed to make the code more likely to compile on Ubuntu without addressing the underlying bugs: - **Replaced `CommonCrypto/CommonDigest.h` with `openssl/md5.h`:** Ubuntu systems typically use OpenSSL for cryptographic functions. - **Replaced `CC_MD5` prefixes with `MD5`:** OpenSSL uses `MD5_` instead of `CC_MD5_`. **Important:** This code still contains the original bugs. It's essential to understand and fix them before using this code in a real-world scenario.
