FAQ

Common questions

Is MD5 safe to use for passwords?
No. MD5 is fast and not collision-resistant, which makes it unsuitable for password storage — use a slow, salted algorithm like the bcrypt generator instead. MD5 is still fine for non-security uses like checksums or cache keys.
Is my text sent anywhere?
No. The hash is computed entirely in your browser using JavaScript — nothing is transmitted, logged, or stored.

Understanding MD5 Hash

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically expressed as a 32-character hexadecimal number.

Key Features

  1. Fixed Output Length: Always produces a 32-character hexadecimal string.
  2. Deterministic: Same input always produces the same output.
  3. Quick Computation: Very fast processing of input data.
  4. Avalanche Effect: Small changes in input create large changes in output.

Common Uses

  • File integrity verification.
  • Password hashing (historical, not recommended for current use).
  • Checksum generation.
  • Data deduplication.
  • Cache keys.

Security Considerations

  1. Not Cryptographically Secure: MD5 is vulnerable to collision attacks.
  2. Not for Passwords: Use modern algorithms like bcrypt, Argon2, or PBKDF2.
  3. Still Useful: Valid for non-security critical applications like checksums.

Example Applications

  • Download verification.
  • Database record indexing.
  • Content-based file identification.
  • Cache management systems.
  • Legacy system compatibility.

Best Practices

  1. Use for checksums and verification only.
  2. Implement with proper input validation.
  3. Consider SHA-256 for security-critical applications.
  4. Maintain compatibility with legacy systems when needed.
