Cipher 和 plain
WebCipher类使用工厂模式来创建加密器和解密器对象,它提供了多个静态方法来获取加密器和解密器对象。常用的方法包括: getInstance(String transformation):根据给定的加密算法名称、加密模式和填充方式创建Cipher对象。 WebFeb 3, 2024 · Therefore, this type of encryption works bit-by-bit, using keystreams to generate ciphertext for arbitrary lengths of plain text messages. The cipher combines a key (128/256 bits) and a nonce digit (64-128 bits) to produce the keystream — a pseudorandom number XORed with the plaintext to produce ciphertext. While the key and the nonce can …
