• function could potentially contain any binary character, it is possible to return a ciphertext containing a system delimiter where one did not previously exist.

  函数返回的字符串可能包含二进制字符，所以可能返回包含系统定界字符的密文，而这个定界字符之前是不存在的。

• to use md5 or higher, you can explicitly call the crypt() function along with the md5() function both in the plaintext and salt arguments to get a random ciphertext (see listing 5).

  要使用md5或更高版本的 salt，您可以显式调用明文和salt参数中的crypt()函数以及md5()函数，以获取随机暗文（参见清单5）。

• the size of the ciphertext was a constant and independent of the size of the ring.

  密文的大小是一个常量，并且与环的大小无关。

• note that there is also a method called ciphertext stealing for cbc.

  请注意，cbc还有一种称为密文窃取的方法。

• decryption process uses digital method. the original image can be retrieved from the ciphertext and security keys by means of phase retrieval algorithm.

  解密过程采用数字方法，利用相位恢复迭代算法即可由密文和密钥恢复原始图像。

• three are ciphers that can take input plaintexts of large and varying lengths and will output the ith block of the ciphertext after having processed only the first i blocks of the plaintext.

  这些加密都可以对输入数据量很大并且长度可变的明文进行加密，但是只有在明文的前 个分组处理完毕后才输出密文的第个分组。

• decryption is the process of converting ciphertext back into its original format, sometimes called plaintext.

  反过来，解密则是将密码文件重新转变成其原始文件形式的方法。
