Class GCMParameters

java.lang.Object

java.security.AlgorithmParametersSpi

org.conscrypt.GCMParameters

@Internal
public final class GCMParameters
extends AlgorithmParametersSpi

GCM parameters used during an ciphering operation with OpenSSLCipher. This class is used internally for backward compatibility with Android versions that did not have the GCMParameterSpec class, in addition to being the implementation of the GCM AlgorithmParameters implementation.

The only supported encoding format is ASN.1, as specified in RFC 5084 section 3.2.
