A hash cannot be reversed. SHA-1 remains available for compatibility but should not be used for modern security.

How to use this hash generator

  1. Paste the exact text to hash and choose SHA-1, SHA-256, SHA-384, or SHA-512.
  2. Review the selected algorithm and generated hash. Edit anything that does not fit, or change the controls and generate another version.
  3. Check the output against the source, then copy or download the finished result.

About this hash generator

Hash Generator helps you create SHA-1, SHA-256, SHA-384, or SHA-512 hashes with Web Crypto. The input and result appear together for easy comparison.

You can also use it to change the controls to produce a different result.

Example

Hash the same text twice with SHA-256. Identical input produces the same digest, while a one-character change produces a different value.

Common uses

  • create SHA-1, SHA-256, SHA-384, or SHA-512 hashes with Web Crypto
  • change the controls to produce a different result
  • copy a useful result into the project it belongs to
