Frequently Asked Questions
Is Cipherly safe for production data?
Yes. Cipherly uses the browser's native Web Crypto API. All operations occur in your device's memory. No data is sent to our servers, ever.
Which encryption mode is best?
For general text, AES-GCM is highly recommended. It provides both confidentiality and integrity, making it the industry standard.
What is the difference between Hashing and Encryption?
Encryption is two-way (can be decrypted with a key). Hashing is one-way (cannot be reversed), making it ideal for passwords.
Can I use Cipherly offline?
Yes. Once the site is loaded, all tools work offline as they rely solely on your browser's processing power.
