Hash Generator

Generate SHA-1, SHA-256 and SHA-512 hashes of your text.

A hash generator computes a fixed-size hash of your text using algorithms like SHA-256, useful for checksums and integrity verification.

How to Use the Hash Generator

  1. Paste your text. Enter the text to hash.
  2. Choose an algorithm. Pick SHA-256, SHA-1, SHA-384 or SHA-512.
  3. Copy the result. Get the hex-encoded hash.

What Is Hash Generator?

Hashing produces a fixed-size digest of your data that is used for integrity checks, password storage and deduplication.

What is a hash?

A hash function maps data of any size to a fixed-length string. It is one-way (you cannot recover the input) and deterministic (same input always gives the same hash).

Which algorithm to use

SHA-256 is the recommended default and is widely used for integrity and certificates. SHA-1 is older and weaker; SHA-512 and SHA-384 offer longer digests.

Key Features

  • SHA-256, SHA-1, SHA-384, SHA-512
  • Hex output
  • Local, using Web Crypto

Examples

  • A SHA-256 hash is 64 hex characters.

Common Use Cases

  • Checksums
  • Integrity verification
  • Fingerprinting

Tips & Best Practices

  • Use SHA-256 or stronger for security-sensitive applications.

Limitations

  • Hashes are for integrity, not password storage without salting.
