How to use
- Paste your text. Any UTF-8 input.
- Pick output format. Hex (default), base64, or base64url.
Common use cases
- Checksumming small inputs
- Generating cache keys
- Legacy system integration
Frequently asked questions
- Is MD5 still safe to use?
- No, not for security. MD5 is cryptographically broken: collisions can be produced in seconds, so it must never be used for password storage, digital signatures, or integrity against an attacker. It is fine for non-security uses like cache keys, checksums against accidental corruption, and legacy compatibility.
- How long is an MD5 digest?
- An MD5 hash is 128 bits, usually shown as 32 hexadecimal characters (or 24 chars in Base64).
- Does this MD5 generator work in the browser?
- Yes. The hash is computed locally with the spark-md5 library, so your input never leaves your machine.
- What should I use instead of MD5 for security?
- For integrity and signatures use SHA-256 or SHA-512. For password hashing use a memory-hard function like bcrypt, scrypt, or Argon2. See the Hash Generator for side-by-side comparisons across modern algorithms.
