FAQ
What's the difference between symmetric and asymmetric encryption?
Symmetric uses the same key for encryption and decryption; asymmetric uses a public key to encrypt and a private key to decrypt.
What is an IV and why is it needed?
IV (Initialization Vector) is required by certain block modes (CBC/CFB/OFB/CTR) to produce different ciphertexts for identical plaintexts.
