Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes. Compute multiple at once.

About hash functions: Cryptographic hash functions produce a fixed-size fingerprint of any input — identical inputs always produce the same hash, and even a one-character change completely alters the output. SHA-256 and SHA-512 are the current standards for security-sensitive use cases like password storage, digital signatures, and file integrity verification. MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security purposes like checksums or legacy compatibility.
