SELECT DecryptByPassPhrase('MySecretPassphrase', EncryptedData) AS DecryptedData; 这将返回原始的SensitiveData。 另外,SQL Server还提供了其他加密函数和选项,如EncryptByKey、DecryptByKey等,可以根据具体需求选择合适的加密方式。 需要注意的是,使用SQL Encrypt功能时,需要妥善管理加密所需的密码,确保只有授权的用户...
EncryptByKey uses a symmetric key. This key must be open. If the symmetric key is already open in the current session, you do not have to open it again in the context of the query. The authenticator helps you deter whole-value substitution of encrypted fields. For example, consider the ...

The SQL Server ENCRYPTBYKEY built-in function uses CBC mode and therefore it is subject to this error-propagation mechanism and data tampering threat. Without using any integrity checks (i.e. if the default @add_authenticator is not set), an adversary may be able to manipulate the ciphertext...
