What is the md5 generator?

The MD5 generator calculates the MD5 hash of your text, a 32 character hexadecimal fingerprint. The text is encoded as UTF-8, so the result is identical to PHP's md5() or the md5sum command. Everything is calculated in your browser.

MD5 is great for checksums, cache keys, deduplication and Gravatar URLs. It's not suitable for storing passwords anymore: use bcrypt or Argon2 for that.

How to use the md5 generator

  1. 1Type or paste the text.
  2. 2Press Convert to calculate the hash.
  3. 3Copy the 32 character MD5 hash.

Frequently asked questions

Can an MD5 hash be decrypted?

No, hashing is one-way. Short or common inputs can still be found in lookup tables, which is why MD5 isn't safe for passwords.

Is MD5 secure?

Not for security purposes, collisions can be created. It's still fine for checksums and identifiers.

Is MD5 case sensitive?

Yes, a single different character, including its case, produces a completely different hash.

How long is an MD5 hash?

128 bits, written as 32 hexadecimal characters.
