Frequently asked questions
Which SHA should I use?
SHA-256 is the modern default (Bitcoin, TLS, JWT). SHA-1 is deprecated (collisions known since 2017). SHA-384/512 for high-security or future-proofing.
Is SHA the same as MD5?
Both are hash functions. MD5 is broken (don't use). SHA-1 is broken. SHA-256+ are still secure as of 2026.
Does it use the browser's crypto?
Yes — Web Crypto API's subtle.digest. Native, fast, and well-tested.
Can I hash a file?
Not in this version (text only). For file hashing, use a checksum tool or write a one-liner with the Web Crypto API.
What about HMAC-SHA?
Different beast — that's authenticated hashing with a secret key. Not provided here.
