描述
Currently BlockCipher interface has methods without letting caller to specify length/offset. In some use cases like Presto, it is needed to pass in a byte array and the data to be encrypted only occupys partially of the array. So we need to add a new methods something like below for decrypt. Similar methods might be needed for encrypt.
byte[] decrypt(byte[] ciphertext, int cipherTextOffset, int cipherTextLength, byte[] aad);

调研方向
从 BlockCipher 接口入手,检查其实现和调用方,以了解当前如何处理加密和解密输入。当解密可以提供 offset 和 length,并且相应的加密方法以一致的方式定义,相关行为也由测试覆盖时,这项工作就完成了。
