Frequently Asked Questions

What is a hash?

A hash is a fixed-length string generated from input data using a mathematical algorithm. The same input always produces the same hash, but you cannot reverse it back to the original data.

What is the difference between SHA-1, SHA-256, and SHA-512?

They differ in output length and security. SHA-1 produces a 160-bit hash, SHA-256 a 256-bit hash, and SHA-512 a 512-bit hash. SHA-256 and SHA-512 are recommended for security-sensitive applications.

Is this hash generator private? Does it send my data to a server?

No. All hashing runs on your computer via the Web Crypto API — your text never leaves your device, and the tool works offline.
