由于任何加密密钥和密码系统都必须位于源代码中，因此同时还会将应用程序的源数据流公开出来。
Since any required encryption keys and cryptosystems have to be in the source code as well, you've also just opened up your source data stream to the world.
加密密钥用于加密nas和RADIUS服务器之间的数据传输。
The encryption key is used to encrypt the data transfer between the NAS and the RADIUS server.
XML加密标记中存在着解密需要的所有信息：加密算法的名称、加密的数据类型以及加密密钥的名称。
All the information necessary for decryption is present within the XML encryption tags: the name of the encryption algorithm, the type of data that was encrypted, and the name of the encryption key.
步骤4：用解密密钥和需要解密的加密数据所在的位置创建Decryptor对象。
Step 4: Create the Decryptor object with decryption key and the location of the encrypted data that is to be decrypted.
我们也可以引用外部加密数据或加密密钥。
We can also refer to external encrypted data or encrypted keys.
头包括一些关于消息的元数据，它可以是一个事务ID或者加密密钥。
The header can contain some metadata about the message, which could be a transaction ID or encryption keys.
如果试图访问数据时无法读取数据，原因之一是解密密钥无效，原因之二是遭服务器拒绝，因为此提供商使用的是自己的加密算法。
If you can't read the data when you have accessed it, the decryption keys are corrupted, or the server rejects it because the vendor is using its own encryption algorithm.
另一个流行的秘密密钥加密系统是国际数据加密算法(IDEA)。
Another popular secret-key cryptosystem is the International Data Encryption Algorithm (IDEA).
为加密文件数据，必须选择一个加密密钥口令，TivoliStorageManager使用它来生成加密密钥，以加密和解密文件数据。
To encrypt file data, an encryption key password must be selected, which Tivoli Storage Manager uses to generate the encryption key for encrypting and decrypting the file data.
Wiggs建议把加密密钥或其他敏感数据保存在字节数组中，那样能够在不需要的时候就会被重写为零。
Wiggs suggests keeping crypto keys or other sensitive data in byte arrays which should be overwritten with zero as soon as they are no longer used.
注意，更改加密密钥时可能需要一个有效的维护窗口。所有已经被加密的数据需要用旧的密钥进行解密，然后用新的密钥加密。
Note that changing an encryption key may require a significant maintenance window; all existing encrypted data will require decryption with the old key and encryption with the new key.
如果由于某些原因无法还原加密密钥，报表服务器将永远无法解密和使用由该密钥加密的所有数据。
If for some reason you cannot restore the encryption key, the report server will never be able to decrypt and use any data that is encrypted with that key.
解密时，通过使用加密密钥将经过编码的数据转换为原始文本。
While in decryption, scrambled data is turned back into the original text by using a cryptographic key.
设计一种高效安全的管理方案来解决数据库中加密密钥的分配与管理问题。
Designing an effective safe management scheme to resolve the database encryption key for the allocation and management issues.
与加密盒式带上的数据相关的一个问题是为用不同加密密钥加密的多个盒式带保持和管理加密密钥的拷贝。
One concern with encrypting data on a tape cartridge is maintaining and managing copies of encryption keys for numerous tape cartridges encrypted with different encryption keys.
I／O管理器代码8可使用加密引擎10，该加密引擎10执行操作以使用一个或多个加密密钥对耦合的可更换存储介质4上的数据加密和解密。
The I/O manager code 8 may use the encryption engine 10, which performs operations to encrypt and decrypt data on a coupled removable storage media 4 using one or more encryption keys.
即先用RSA方法加密密钥矩阵，然后用二叉树的遍历产生的不同密钥数据矩阵对数据进行加密。
First, produce key with RSA and construct a binary tree, then traverse the binary tree to produce new keys. And there must be a certain key to encrypt data with all the other encoding methods.
