Enum CipherStrategy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<CipherStrategy>
    public enum CipherStrategy
extends java.lang.Enum<CipherStrategy>

    CipherStrategy enumerates the few strategies for a Cipher used by SAPERION.

    It defines the encryption algorithm, block mode, padding type and key size to use.

    If a new strategy is really needed, a new entry must be made and a new corresponding Cipher-implementation must be provided.

      • values

        public static CipherStrategy[] 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 (CipherStrategy c : CipherStrategy.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static CipherStrategy 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

      • getAlgorithm

        public java.lang.String getAlgorithm()
        Returns the name of the encryption algorithm of this CipherStrategy.

      • getMode

        public java.lang.String getMode()
        Returns the name of the mode of this CipherStrategy.
        Returns:
        the mode

      • getPadding

        public java.lang.String getPadding()
        Returns the name of the padding of this CipherStrategy.
        Returns:
        the padding
