Frequently Asked Questions

This free online hash generator supports MD5, SHA-1, SHA-256, SHA-384 and SHA-512 algorithms, plus HMAC variants for each. SHA-256 and SHA-512 are recommended for modern applications requiring strong cryptographic hash values.
HMAC (Hash-based Message Authentication Code) combines a secret key with a hash algorithm to produce a keyed hash value. It verifies both data integrity and authenticity, commonly used for API request signing and JWT token verification.
Yes. Select multiple algorithms and the tool generates hash values for all of them simultaneously from a single input. Compare SHA-256, SHA-512 and MD5 hashes side by side.
Yes. All hash computations run entirely in your browser using JavaScript. Your input data never leaves your device, keeping passwords and sensitive content completely private.
