What is a cryptographic hash function?

A hash function is a mathematical algorithm that maps arbitrary-sized data to a fixed-size string of characters. It is deterministic, fast to compute, and irreversible.

Can a hash be decrypted?

No, cryptographic hashes are one-way functions. You cannot reverse a hash back into the original plain text.

What is SHA-256 used for?

SHA-256 is widely used in SSL/TLS certificates, Bitcoin and cryptocurrency mining, git commit identification, and file checksum verification.

Yes, hashing is performed locally inside your browser using window.crypto.subtle. No data is transmitted to any server.
