Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. Verify file integrity with drag-and-drop checksum comparison. All processing happens in your browser using the Web Crypto API.
Hash Algorithm Reference
MD5 (128-bit)
Fast but cryptographically broken. Do not use for security. Still used for non-security checksums (file integrity, deduplication). Produces 32 hex characters.
SHA-1 (160-bit)
Deprecated for security. Collision attacks demonstrated. Still used in Git commit hashes and some legacy systems. Produces 40 hex characters.
SHA-256 (256-bit)
Industry standard for integrity verification. Used in TLS, code signing, and blockchain. Recommended for all new applications. Produces 64 hex characters.
SHA-512 (512-bit)
Maximum security hash. Faster than SHA-256 on 64-bit systems. Used in high-security applications and some password hashing schemes. Produces 128 hex characters.
