FAQ
Is MD5 safe for passwords?
No. MD5 is cryptographically broken and should never be used for password storage. Use bcrypt, scrypt, or Argon2 for passwords. MD5 is still fine for non-security checksums like file integrity.
Can I hash files instead of text?
This tool hashes text input. For file hashing, use the command line (shasum on macOS, certutil on Windows) or a dedicated file hash utility.
What is the difference between SHA-256 and SHA-512?
SHA-256 produces a 256-bit (64-character hex) hash. SHA-512 produces a 512-bit (128-character hex) hash. Both belong to the SHA-2 family. SHA-512 is more collision-resistant but slower on 32-bit systems.
