this purpose fine. Unlike MAC, they don't require keys to create the hash. Instead, they rely on standard, readily-available algorithms. A popular hashing algorithm is MD5, which is universally supported on both UNIX and Windows with standard tools, some already bundled with the operating system, others free for download on the Web. MD5 is a 128-bit one-way hash, which means it can only be encrypted, but it also doesn't need to be decrypted. But that's not the point because hashing isn't about confidentiality. It's about integrity. For example, the hashed message can be sent separately from the original message. The receiver can take the message, use an MD5 tool to hash it on their side, and then compare it with the hash sent with the original message. If the two match, then the message hasn't been touched or altered in transit.
