Hash Generator

The Hash Generator computes cryptographic and non-cryptographic hashes of text or files — MD5, SHA-1, SHA-256, SHA-384, SHA-512 — using the browser's native Web Crypto API. Hashing turns arbitrary input into a fixed-length fingerprint; the same input always produces the same hash, and any change to the input produces a completely different output.

Developers use hashes for file-integrity checks (compare a download's SHA-256 against the vendor's published value), API request signing (HMAC), password derivation (though bcrypt/argon2 are better for that), cache keys, deduplication, and content-addressable storage. Security engineers use them for forensics — a file's SHA-256 uniquely identifies it and can be cross-referenced against threat intelligence feeds.

Note that MD5 and SHA-1 are considered cryptographically broken — collisions can be found. Use them only for non-security purposes like cache keys or ETag generation. For anything security-critical, use SHA-256 or SHA-512. For password hashing, use a dedicated password-hashing function (argon2, bcrypt, scrypt) — never a plain hash.
