SHA Hash Generator

Generate SHA-1, SHA-256 or SHA-512 hashes locally. Free, private and instant.

About the SHA Hash Generator

A hash turns any text into a fixed-length fingerprint. The same input always gives the same output, and the original cannot be recovered.

When to use it

Use it to verify file or text integrity and compare checksums. Do not use plain SHA hashes alone to store passwords.

What a hash is

A cryptographic hash function turns input of any size into a fixed-length output. Changing even one character produces a completely different result, which is why hashes are used to spot tampering.

SHA-1, SHA-256 and SHA-512

SHA-256 and SHA-512 belong to the SHA-2 family and are widely used today. SHA-1 is considered weak against deliberate collisions and should not be used for security, although it still appears in legacy checksums.

Hashing is not encryption

Encryption can be reversed with a key, but a hash cannot be reversed. Do not store passwords with a plain SHA hash. Use a slow password hashing algorithm such as bcrypt, scrypt or Argon2 with a salt.

Verifying downloads

Publishers often list a SHA-256 checksum next to a download. Hash what you received and compare. If the values match exactly, the data is intact. This tool hashes text you type or paste, not files.

How to use the SHA Hash Generator
