Hash Generator

Computes a hash of any input text using MD5, SHA-1, SHA-256, or SHA-512. Useful for verifying file or data integrity by comparing a computed hash against a published checksum. MD5 and SHA-1 are both cryptographically broken and unsuitable for anything security-sensitive like password storage, but remain fine for non-adversarial integrity checks. None of these algorithms — including SHA-256/512 — are appropriate for hashing passwords directly; that requires a purpose-built algorithm like bcrypt or Argon2 that's deliberately slow to resist brute-force attempts.

Any change to the input, even a single character, produces a completely different hash — there's no such thing as a "close" match, which is exactly why hashes work for integrity checks but not for finding near-duplicate content.
