对称加密算法从加密模式上可分为流密码(序列密码)和分组密码(块密码)两大类，几乎当前使用的所有对称加密算法都是基于分组密码模式。
It can be divided into two sorts as stream cipher mode and block cipher mode by encrypting mode. The most commonly used symmetric encryption algorithms are almost based on block cipher mode.
算法被称作流密码(stream cipher)还是块密码(block cipher)，取决于算法转换消息时是一次一个字节还是一次一个块(8个字节)。
The algorithm is referred to as a stream or block cipher depending on whether the algorithm transforms the message one byte at a time or a block (eight bytes) at a time.
即美国国家数据加密标准(the United States DataEncryption Standard)，是一个块密码算法，块长8字节，密钥长56位。
DES, the United States Data Encryption Standard, is a block cipher algorithm with 8-byte long blocks and a key length of 56 bits.
这类驱动器包含了一块有密码保护的硬件加密芯片。
These devices come embedded with a hardware encryption chip that's password protected.
如果密码达到最健壮的级别，那么整个指示器将添满绿色块。
The password is the strongest when the entire meter is completely full with green blocks.
当用户单击ok或按enter键以从用户名移向密码输入时，将执行上面所示的逻辑代码块。
When the user clicks OK or presses Enter to move from user name to password entry, the logic block shown above is executed.
在这个演示中，我使用了SunJCE密码术供应商的tripledes块加密算法。
In this demonstration, I use the TripleDES block encryption algorithm of the SunJCE cryptography provider.
加密方式是块大小为 8 字节的CBC（CipherBlockChaining，密码块链接）。
The mode of encryption is CBC (Cipher Block Chaining) with 8-byte block size.

This piece of RNA can then direct the synthesis of proteins via the genetic code.
说明：实现了SSE (SSE简单流加密算法)，该算法具有块加密与流密码特性的加密算法。
It implements SSE (SSE simple stream encryption algorithm), the algorithm has characteristics of stream ciphers and block cipher encryption algorithm.
AC分组密码的设计结合了宽轨迹策略和比特块技术，以确保算法对差分密码分析和线性密码分析的安全性。
The cipher design combines the wide trail strategy and bit-slice technology that ensure the resistance AC against differential and linear cryptanalysis.
