Hash Generator (MD5, SHA-1, SHA-256, SHA-512)
Generate MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 and CRC32 checksums of any text, instantly and privately in your browser.
How to use
- 1Type or paste your text.
- 2All hashes are calculated as you type — copy the one you need.
How it's calculated
Text is encoded as UTF-8, then hashed with each algorithm as specified in RFC 1321 (MD5) and FIPS 180-4 (SHA family).
Frequently asked questions
Is MD5 still safe?
Not for security. MD5 and SHA-1 have practical collision attacks. Use SHA-256 or better for integrity, and a slow hash like bcrypt or Argon2 for passwords.
Can a hash be reversed?
No — hashes are one-way. Short or common inputs can be guessed from lookup tables, though, which is why passwords need salts.
Why does my hash differ from another tool?
Check for trailing spaces or new lines and the text encoding. We hash exactly the UTF-8 bytes of what's in the box.
