      static Mode valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.

      • 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.
      • CFB

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

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

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

        public static final Mode CTS
        The CTS operation mode that represents the Cipher Text Stealing, as described in Bruce Schneier’s book Applied Cryptography-Second Edition, John Wiley and Sons, 1996

        public static final Mode ECB
        The ECB operation mode that represents the Electronic Codebook Mode, as defined in FIPS PUB 81 (generally this mode should not be used for multiple blocks of data).

        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.

      • values

        public static Mode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Mode c : Mode.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Mode valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
