About MD5
MD5 (Message-Digest Algorithm 5) was designed by Ronald Rivest in 1991 as a faster, more secure successor to MD4. It produces a 128-bit (16-byte) digest using four 32-bit state variables and 64 rounds of processing. MD5 was once a dominant checksum and authentication tool, but multiple practical collision attacks have been demonstrated since 2004 — most notably by Marc Stevens, who produced chosen-prefix collisions in under a minute on modern hardware. MD5 should never be used for cryptographic security, but remains common for non-security checksums (e.g. verifying file downloads where tampering isn't a concern).

Only for checksums
⚠️ MD5 is cryptographically broken. Collisions can be generated in seconds. Never use MD5 for passwords, digital signatures, or any security application.
