FAQ
How are cryptographic hashes computed?
Hashes are calculated locally in your browser using the native Web Crypto API (`crypto.subtle.digest`) for maximum security and performance.
Which hash algorithm is recommended for security?
SHA-256 and SHA-512 are standard for cryptographic security. MD5 and SHA-1 should only be used for legacy checksum verification.
Does case sensitivity matter in input?
Yes. Cryptographic hash functions are strictly case-sensitive; even a single character case difference produces a completely different hash digest.
Can I generate hashes in uppercase?
Yes. Check 'UPPERCASE hex letters' in the options panel.
