Popular Questions
Q: Do hashes or encryption/decryption keys get cached on a server?
A: Absolutely not. All crypto functions are executed locally, maintaining standard air-gapped security hygiene.
Q: How fast can I verify a massive list of MD5 or SHA strings?
A: The page processes bulk inputs locally via Web Workers, giving you instant results without network lag.
Q: Can I decode suspicious base64 payloads here without risk?
A: Yes. Since the decoding doesn't execute anything server-side, you can check malicious strings safely inside an isolated tab.
