data decryption的意思|示意

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.

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。

You can use the encryption and decryption built-in functions encrypt, DECRYPT_BIN, DECRYPT_CHAR, and GETHINT to encrypt your data within database tables.

可以使用内置的加密和解密函数encrypt、DECRYPT _ BIN、DECRYPT_CHAR和GETHINT加密数据库表中的数据。

MD5 encryption is one-way encryption algorithm, the so-called one-way encryption is only for data encryption, In other words, there is no way to encrypt the data after decryption.

MD 5就是采用单向加密的加密算法，所谓单向加密就是只能对数据进行加密，也就是说，没有办法对加密以后的数据进行解密。

Software can help to carry out authentication or data encryption/decryption operations, but hardware has advantages in better performance and higher level security.

软件当然可以实现身份认证和数据加密解密的功能，但是硬件具有更好的性能和更高的安全等级。

When the piracy occurring, the data supplier not only can trace the traitor but also can revoke the decryption ability of the traitor's private key by updating the code vectors of the users.

当发生盗版时，数据发行商不但可以追踪到叛逆者，而且可以通过更新用户的码向量来废除叛逆者的秘密钥的解密能力。
