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.
