Frequently Asked Questions

What is a hash?

A hash is a fixed-size string generated from input data using a mathematical algorithm. The same input always produces the same hash, but even a small change in input creates a completely different hash.

What's the difference between MD5, SHA-1, SHA-256, and SHA-512?

MD5 and SHA-1 are older algorithms (MD5: 128-bit, SHA-1: 160-bit). SHA-256 and SHA-512 are more secure (256-bit and 512-bit respectively). SHA-256 is recommended for most security purposes.

Is my data secure?

Yes! All hashing happens in your browser. We never see, store, or transmit your data. Your privacy is completely protected.

What are hashes used for?

Hashes are used for data verification, password storage (with salt), checksums, digital signatures, and ensuring data integrity.
