public enum Mode extends Enum<Mode>
The enum Mode defines the names that can be specified as the mode component in a transformation when requesting an instance of Cipher. For more info see: https://docs.oracle.com/en/java/javase/11/docs/specs/security/standard-names.html#cipher-algorithm-modes

  • Enum Constant Details

    • BC

      public static final Mode BC
      The BC mode that represents the Block Chaining Mode

    • CBC

      public static final Mode CBC
      The CBC operation mode that represents the Cipher Block Chaining Mode, as defined in FIPS PUB 81. Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher’s actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the “DES/CFB8/NoPadding” and “DES/OFB32/PKCS5Padding” transformations. If no such number is specified, a provider-specific default is used. (For example, the SunJCE provider uses a default of 64 bits for DES.) Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8-bit mode such as CFB8 or OFB8.

    • CCM

      public static final Mode CCM
      The CCM operation mode that represents the Counter/CBC Mode, as defined in NIST Special Publication SP 800-38D

    • CFB

      public static final Mode CFB
      The CFB operation mode that represents the Cipher Block Feedback Mode, as defined in FIPS PUB 81

      The CFBx operation mode that represents the Cipher Block Feedback Mode, as defined in FIPS PUB 81

      public static final Mode CTR
      The CTR operation mode that represents a simplification of OFB, Counter mode updates the input block as a counter.

      The OFB operation mode that represents the Output Feedback Mode, as defined in FIPS PUB 81 Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher’s actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the “DES/CFB8/NoPadding” and “DES/OFB32/PKCS5Padding” transformations.
