Frequently Asked Questions
What is AES encryption?
AES (Advanced Encryption Standard) is a symmetric block cipher that encrypts data using the same key for encryption and decryption. It uses 128, 192, or 256-bit keys. AES-256 in GCM mode is the modern recommended standard for data encryption.
When should I use RSA vs AES encryption?
Use AES for encrypting bulk data — it's fast and efficient. Use RSA for encrypting small amounts of data (like AES keys) or for digital signatures. In practice, hybrid encryption combines both: RSA encrypts an AES session key, then AES encrypts the data.
What is PGP encryption?
PGP (Pretty Good Privacy) uses public-key cryptography for end-to-end encrypted email and file encryption. The sender encrypts with the recipient's public key; only the recipient's private key can decrypt. OpenPGP is the open standard version.
Is client-side encryption safe?
Client-side encryption means your data is processed entirely in your browser — no data is sent to our servers. This is safe for testing and development purposes. For production encryption, use battle-tested libraries and proper key management.
