Hash Generator
Compute MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 of any text — all at once.
Algorithm notes
SHA-1, SHA-256, SHA-384 and SHA-512 are computed with the browser's native Web Crypto engine. MD5 and CRC32 are implemented locally in JavaScript because Web Crypto does not provide them — they are still widely needed for legacy checksums and dedup tables. For security purposes (signatures, password storage) use SHA-256 or stronger; MD5 and SHA-1 are broken for collision resistance.
FAQ
Can I hash files?
File hashing is on the roadmap — the current version handles text only.
Is HMAC supported?
Keyed hashing is planned as a separate tool.
Is my text uploaded?
No. All hashing runs locally via Web Crypto.
