Static Methods

aes128(Uint8List keySeed, {bool paceMode = false}) → Uint8List
Returns key for AES-128 derived from keySeed bytes and counter mode 1. If paceMode is true counter 3 is used.
aes192(Uint8List keySeed, {bool paceMode = false}) → Uint8List
Returns key for AES-192 derived from keySeed bytes and counter mode 1. If paceMode is true counter 3 is used.
aes256(Uint8List keySeed, {bool paceMode = false}) → Uint8List
Returns key for AES-256 derived from keySeed bytes and counter mode 1. If paceMode is true counter 3 is used.
cmac128(Uint8List keySeed) → Uint8List
Returns key for CMAC-128 derived from keySeed bytes and counter mode 2.
cmac192(Uint8List keySeed) → Uint8List
Returns key for CMAC-192 derived from keySeed bytes and counter mode 2.
cmac256(Uint8List keySeed) → Uint8List
Returns key for CMAC-256 derived from keySeed bytes and counter mode 2.
derive(DeriveKeyType keyType, Uint8List keySeed, {bool paceMode = false}) → Uint8List
Returns key from keySeed bytes for specific keyType and counter mode specific for key type (1 - ENC mode, 2 - MAC mode). If paceMode is true counter 3 for encryption key types.
desEDE(Uint8List keySeed, {bool paceMode = false}) → Uint8List
Returns key for DESede derived from keySeed bytes and counter mode 1. If paceMode is true counter 3 is used.
iso9797MacAlg3(Uint8List keySeed) → Uint8List
Returns key for ISO9797 MAC algorithm 3 derived from keySeed bytes and counter mode 2.
