What is MD5?
MD5 (Message Digest 5) is a cryptographic hash function that produces a 128-bit (32 hexadecimal character) hash value. It was designed by Ronald Rivest in 1991 and is still widely used today for non-security checksums.
MD5 vs SHA-256
- MD5 — 32 character output, faster, not collision-resistant, suitable for checksums only
- SHA-256 — 64 character output, slower, more secure, recommended for security applications
When to Use MD5
- Verifying downloaded file integrity (compare hash before and after)
- Database checksums to detect data corruption
- Non-security deduplication (detecting duplicate files)
- Caching keys and ETag generation
Frequently Asked Questions
What is an MD5 hash?+
A 128-bit fingerprint of any input. The same input always produces the same hash, but you cannot reverse a hash back to the original text.
Is MD5 secure for passwords?+
No. MD5 is fast, making it vulnerable to brute-force attacks. Use bcrypt or Argon2 for passwords.
What is MD5 used for?+
Verifying file integrity, checksums, and non-security fingerprinting. Not recommended for security-sensitive applications.
Is my text sent to a server?+
No. The hash is generated entirely in your browser using the SubtleCrypto API.
Is it free?+
Yes, 100% free with no signup.
