Hash Generator
Generate cryptographic hashes of any text using the Web Crypto API plus MD5 for legacy needs — useful for checksums, deduplication and integrity checks.
FAQ
Which hash algorithms are supported?
SHA-256, SHA-512, SHA-384, SHA-1 (Web Crypto) and MD5 (for legacy checksums).
Is my text uploaded anywhere?
No — hashing happens entirely in your browser; nothing is transmitted.
Which algorithm should I use?
SHA-256 is the modern default. MD5 and SHA-1 are fast but cryptographically broken — use only for legacy checksums.
