What hash algorithms are supported?

We support SHA-1, SHA-256, SHA-384, and SHA-512 hash algorithms. These are the most widely used cryptographic hash functions in web development and security.

Are the generated hashes secure?

The hashes are generated using the Web Crypto API built into your browser, ensuring cryptographically secure results. SHA-256 and above are recommended for security-sensitive applications.

Can I reverse a hash back to the original text?

No, cryptographic hash functions are one-way operations. It is computationally infeasible to reverse a hash back to its original input. This is by design for security purposes.
