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.

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。

As the encryption algorithm and decryption algorithm are open to everyone, so the private key storage management becomes an insecure part in public key system.

在公钥密码系统中加密和解密算法是公开的，因此私钥存储管理成了公钥系统安全中薄弱的环节。
