1.明语电文
2.明码通讯
3.纯文本
1.writing in a computer file that has no special codes and can therefore be used easily by other computer programs
1.In ECB mode, each block of plaintext is encrypted independently of any other block.
在ECB模式中，每块明文都是独立于其他块加密的。
2.As a result of this padding, the length of encrypted data could be greater than the original plaintext.
填充后，加密数据的长度可能大于原始纯文本。
3.It is secure in only the most lenient definition of the word: it keeps plaintext credentials from going out over the wire.
可以使用最朴实的语言来描述它的安全性：它可以防止纯文本凭证通过线路传递出去。
4.In a public-key cryptosystem, plaintext encrypted with the public key can only be deciphered with the private key from the same pair.
在公开密钥密码系统中，用明匙加密的普通文本只能由同一对钥匙中的秘密密钥解密。
5.In the transmitter of cryptosystems, the plaintext is encrypted by means of international data encryption algorithms (IDEA).
密码系统之传送端，明文信号以国际资料编码演算法（IDEA）密码器编码。
6.Plaintext (or cleartext) in this context should not be confused with plain text when referring to the format of an e-mail message.
不应将本上下文中的纯文本（或明文）与谈及电子邮件格式时所提到的纯文本混为一谈。
7.Any information can be delivered in the form of plaintext, and secure channel is unnecessary.
所有信息可以明文形式进行传送，不需要安全信道。
8.Whole-value substitution attacks can be thwarted by adding contextual information to the plaintext before encrypting it.
加密纯文本前在该文本中添加上下文信息，可避免上述整个值替换攻击。
9.By means of chosen plaintext attack, the key stream used can easily be recovered with little computing.
通过选择明文攻击，在很小的计算代价下获得了密钥流。
10.By examining the ciphertext, you can use a few heuristic tricks to figure out the plaintext has been shifted two characters.
通过检查暗文并借助一些启发式的技巧，您可以知道，明文实际上是移动了两个字符。
