Propagating Cipher Block

GCM

public static final Mode GCM

GCM 全称为 Galois/Counter Mode。G是指GMAC，C是指CTR。 它在 CTR 加密的基础上增加 GMAC 的特性，解决了 CTR 不能对加密消息进行完整性校验的问题。

Method Detail

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(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
