MD5 Hash Generator
Generate MD5 hashes from any text string. Free, client-side only — no data is ever sent to our servers.
Not for passwords. MD5 is a fast hash — brute-forceable in seconds. Use bcrypt for password storage.
What is MD5?
MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (32 hex character) hash value. It was designed by Ronald Rivest in 1991 and was originally intended for use as a cryptographic hash function.
MD5 is not suitable for password storage — it is too fast and has been cryptographically broken. For password hashing, always use bcrypt or Argon2id instead. Read our guide on bcrypt vs Argon2 to learn more.
Common uses for MD5
- File integrity verification (checksums)
- Non-security data deduplication
- Cache key generation
- Legacy system compatibility
