Hash Generator

Online hash generator & checksum tools

A hash generator turns arbitrary data into a fixed-size fingerprint. Developers use hashes for checksums, deduplication, and (where still required) legacy MD5 verification. SHA-256 and SHA-512 are common choices today for integrity checks and HMAC-based designs; SHA-1 is deprecated for security-sensitive signatures but still appears in older systems and Git object IDs.

MD5 (RFC 1321)

MD5 produces a 128-bit digest, often shown as 32 hex characters. It is fast but cryptographically broken for collision resistance — do not rely on MD5 for passwords or signatures. It remains useful for non-security file checksums and compatibility with existing workflows.

SHA-1

SHA-1 outputs 160 bits. It is no longer considered safe against well-funded attackers for collision attacks on certificates, but the digest is still used in many archival and tooling contexts.

SHA-256 and SHA-512 (SHA-2 family)

SHA-256 (256-bit) and SHA-512 (512-bit) are members of the SHA-2 family defined by NIST. They are widely used in TLS, code signing, blockchain, and general-purpose hashing when collision resistance matters.
