MD5 vs SHA-256: Why You Should Switch Hashes
MD5 is fast but broken for security. See why SHA-256 is the safe default for checksums and password hashing.
Output Size
MD5: 128 bits (32 hex chars). SHA-256: 256 bits (64 hex chars).
Security
MD5 has known collision attacks and is considered broken. SHA-256 is collision-resistant and widely trusted.
Speed
MD5 is faster, which is why it still appears in legacy checksums — but speed is worthless when collisions are feasible.
Best For
MD5: verifying legacy downloads and non-security fingerprints. SHA-256: file integrity, signatures, and any security-sensitive use.
