Class AesCtrCipher

java.lang.Object

javax.crypto.CipherSpi

com.amazonaws.cloudhsm.jce.provider.AesCtrCipher

public class AesCtrCipher
extends javax.crypto.CipherSpi

AesCtrCipher implements CipherSpi for the “AES/CTR/NoPadding” transformation.

For any Cipher::update() or Cipher::doFinal() method, an AesCtrCounterException will be thrown if the counter is exhausted.

CloudHSM does not need a SecureRandom source, as the HSM handles randomness internally. Any source of SecureRandom passed to Cipher methods will be ignored.
