Hash Generator
Create SHA-1, SHA-256, SHA-384, or SHA-512 hashes with Web Crypto.
Runs in your browserA hash cannot be reversed. SHA-1 remains available for compatibility but should not be used for modern security.
How to use this hash generator
- Paste the exact text to hash and choose SHA-1, SHA-256, SHA-384, or SHA-512.
- Review the selected algorithm and generated hash. Edit anything that does not fit, or change the controls and generate another version.
- 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.
