Frequently asked questions
Common questions about Hash Generator
How are hashes computed?
SHA-1, SHA-256, SHA-384, and SHA-512 are calculated using your browser's native Web Crypto API (crypto.subtle). MD5 is computed using a lightweight client-side algorithm since Web Crypto does not support MD5. No data is transmitted across the network.
Which hash algorithm should I use?
SHA-256 and SHA-512 are recommended for cryptographic security and data integrity verification. MD5 and SHA-1 are provided for legacy checksum verification.
