About this tool
Type or paste text and see its MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes at once. They update as you type. The text is converted to UTF-8 first. SHA hashes use the browser's built-in Web Crypto, and MD5 uses a small JavaScript implementation. Nothing is sent to a server. Hashes are one-way fingerprints: the same input always gives the same output, and a tiny change gives a completely different one. MD5 and SHA-1 are no longer considered secure for passwords or signatures.
How to use it
- Enter the text to hash.
- Read all five hashes.
- Copy the one you need.
Example
SHA-384 and SHA-512 lines are also shown for the same input.
Input
hello
Result
MD5: 5d41402abc4b2a76b9719d911017c592 SHA-1: aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 (SHA-384 and SHA-512 follow)
Common problems
- Hash does not match another tool
- Check for a trailing space or newline: "hello" and "hello\n" hash differently. Also confirm both tools hash the text as UTF-8.
- Need to hash a file
- This tool hashes text typed or pasted into the box, not files.
- Using it to store passwords
- Plain MD5 or SHA hashes are fast to crack. Use a slow password hashing function such as bcrypt or Argon2 on your server.
