数据块使用一个对称密钥算法进行加密,它使用一个密钥来实现对数据的加密和解密。
The bulk of the data is encrypted using a symmetric key algorithm that encrypts and decrypts data using a single secure key.
对称算法非常有效,并且可以与用于加密和解密计算的单一密钥一起使用。
Symmetric algorithms are very efficient and work with a single key for both encryption and decryption calculations.
用于数据加密的密钥是使用带有与服务提供者(Service Provider)的 X.509 证书相关联的公钥的非对称算法进行加密的。
The key used for the data encryption is encrypted itself using an asymmetric algorithm with the public key associated with the Service Provider's X.509 certificate.
