Frequently Asked Questions

Which hash algorithm should I use?

SHA-256 is the most common choice for checksums and data verification. SHA-1 is deprecated for security use. SHA-512 offers the highest security margin.

Are these hashes cryptographically secure?

Yes. All hashes are generated using the browser's Web Crypto API (crypto.subtle.digest), which provides cryptographic implementations.

Can I reverse a hash to get the original text?

No. Hash functions are one-way. There is no algorithm to reverse a hash.
