MD5 Generator

Generate an MD5 hash from text or a file. MD5 is fast and still common for legacy checksums, but it is not suitable for password storage or any modern security purpose — practical collision attacks are well known.

MD5 is not suitable for modern security use (password storage, digital signatures, or integrity guarantees against a motivated attacker). Practical collision attacks are known. Use it only for legacy compatibility or non-security checksums — prefer SHA-256 or stronger for anything security-sensitive.

FAQ

Is MD5 safe to use?
Not for security purposes. Practical collision attacks against MD5 are well established, meaning two different inputs can be crafted to produce the same hash. Never use it for password storage, digital signatures, or verifying content you don't trust.
Why does this tool exist, then?
MD5 is still common for legacy compatibility checks and non-adversarial checksums (like confirming a download wasn't corrupted by accident, not tampered with on purpose). For anything security-sensitive, use the SHA-256 Generator instead.
