Constructor Detail

PKCS11GCMParameterSpec

public PKCS11GCMParameterSpec(byte[] iv,
                              byte[] additionalData,
                              long tagBits)

Parameters:

iv - The initialization vector. The length of the initialization vector can be any number between 1 and 2^56. 96-bit (12-byte) IV values can be processed more efficiently, so that length is recommended for situations in which efficiency is critical

additionalData - Additional data. This data is authenticated but not encrypted.

tagBits - Length of the authentication tag (output following cipher text) in bits. Can be between 0 and 128
