How Hash Generator (MD5/SHA-1/SHA-256) works

A cryptographic hash converts input into a fixed-length digest. Small input changes produce very different results, making hashes useful for checksums, integrity comparisons, cache keys, and controlled fingerprinting.

Text is encoded as bytes in the browser. SHA-1 and SHA-256 use the native Web Crypto API, while MD5 uses a bundled local implementation; each digest is displayed as hexadecimal.

MD5 and SHA-1 are broken for collision-resistant security and should not protect passwords or signatures. Password storage requires a salted, deliberately slow algorithm such as Argon2, scrypt, or bcrypt implemented by a trusted authentication system.
