int |
doFinal(byte[] out,
int outOff)
处理最后一块数据
当 Cipher.process(byte[], int, int, byte[], int)处理完数据后非完整块数据,此方法用于处理块中剩余的bytes如加密数据要求128bit,即16byes的整数,单数处理数据后为15bytes,此时根据padding方式不同,可填充剩余1byte为指定值(如填充0) 当对数据进行分段加密时,需要首先多次执行process方法,在最后一块数据处理完后执行此方法。 |
String |
getAlgorithmName()
获取算法名称
|
int |
getBlockSize()
获取块大小,当为Stream方式加密时返回0
|
int |
getOutputSize(int len)
返回输出缓冲区为了保存下一个update或doFinal操作的结果所需的长度(以字节为单位)
下一个update或doFinal调用的实际输出长度可能小于此方法返回的长度。 |
Object |
getRaw()
获取原始对象
|
void |
init(CipherMode mode,
Cipher.Parameters parameters)
初始化模式和参数
|
int |
process(byte[] in,
int inOff,
int len,
byte[] out,
int outOff)
执行运算,可以是加密运算或解密运算
此方法主要处理一块数据,一块数据处理完毕后,应调用 Cipher.doFinal(byte[], int)处理padding等剩余数据。 |
