Enum Class Padding

java.lang.Object

java.lang.Enum<Padding>

org.miaixz.bus.crypto.Padding

All Implemented Interfaces:

Serializable, Comparable<Padding>, Constable

public enum Padding
extends Enum<Padding>

补码方式 补码方式是在分组密码中，当明文长度不是分组长度的整数倍时，需要在最后一个分组中填充一些数据使其凑满一个分组的长度。

Since:

Java 17+

Method Details

values

public static Padding[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static Padding valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
