Database+createKey()+openKey()+encryptData()+closeKey()+decryptData()SymmetricKey+keyID: String+algorithm: String+key: String 结尾 通过以上的步骤和代码示例,相信你已经掌握了如何在 SQL Server 中实现数据库字段内容的加密和解密。这不仅提高了你对数据库安全性的理解,还为将来的数据处理奠定了基础。牢记...
SQL Server中的数据列加密(Column-level Encryption) SQL Server在2005引入了列加密的功能。使得可以利用证书,对称密钥和非对称密钥对特定的列进行加密。在具体的实现上,根据加密解密的方式不同,内置了4对函数用于加密解密: • EncryptByCert() 和DecryptByCert()—利用证书对数据进行加密和解密 • EncryptByAsymK...
使用SELECT语句查询包含加密列的表,并使用DECRYPTBYKEY函数解密数据: SELECTencrypted_column,CONVERT(varchar,DECRYPTBYKEY(encrypted_column))ASdecrypted_columnFROMyour_table_name 1. 2. 请确保替换encrypted_column为实际的加密列名称,your_table_name为包含加密列的表名。 示例 假设有一个名为employees的表,其中包...
