All Implemented Interfaces:

Serializable, Comparable<SymmetricAlgorithmEnum>

public enum SymmetricAlgorithmEnum
extends Enum<SymmetricAlgorithmEnum>

FIXME maybe a better name is just SymmetricAlgorithm Defines the algorithms used for ICP-Brasil (PKI) standard symmetric encryption.

DEFAULT

public static SymmetricAlgorithmEnum DEFAULT

Definition of standard algorithm.

Method Detail

values

public static SymmetricAlgorithmEnum[] 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 (SymmetricAlgorithmEnum c : SymmetricAlgorithmEnum.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SymmetricAlgorithmEnum valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getAlgorithm

public String getAlgorithm()

getKeyAlgorithm

public String getKeyAlgorithm()

getSize

public int getSize()

getSymmetricAlgorithm

public static SymmetricAlgorithmEnum getSymmetricAlgorithm(String algorithm)

Retrieves an item from the enumeration corresponding to the passed parameter. The passed parameter must be equal (case insensitive) to the algorithm name of any item in this enumeration, otherwise it will return null.

Parameters:

algorithm - name

Returns:

representation
