Generate MD5 and SHA hashes online

How it works

1. 1

   Type or paste the text to hash.

2. 2

   Read the five digests below the input.

3. 3

   Copy the one you need.

About the Hash Generator (MD5/SHA)

A hash turns any piece of text into a fixed-length fingerprint: change one character and the fingerprint changes completely. Developers use hashes to compare values, build cache keys and check downloads against published checksums. This generator calculates the MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of the same text side by side, each shown in lowercase hexadecimal.

What you can do

• Get five digests of one input at once: MD5, SHA-1, SHA-256, SHA-384 and SHA-512.
• Hash the UTF-8 bytes of your text, so results match what most languages produce for the same string.
• Copy any one digest with its own button.

When it works best

• Checking that a string produces the same hash as your application code, when a lookup or cache key misses.
• Generating a quick SHA-256 fingerprint of a config value to compare two environments without revealing it.
• Teaching or comparing how digest length grows from MD5's 32 hex characters to SHA-512's 128.

Things to know

• Hashing happens in your browser, using the Web Crypto API for the SHA family.
• It hashes text, not files, and a trailing space or line break changes the result, so trim the input first.
• MD5 and SHA-1 are broken for security purposes and plain hashes are wrong for storing passwords; use the Bcrypt Generator for that.
• To sign a message with a secret key, use the HMAC Generator.
