File processing method and device and computer readable storage medium

The invention provides a file processing method and device and a computer readable storage medium, relates to the technical field of databases, and is used for improving the safety of an SO library. The file processing method provided by the invention comprises the following steps: receiving a hash value of a to-be-processed SO library sent by a client, the to-be-processed SO library comprising ato-be-decrypted node; Obtaining a corresponding key according to the hash value; And sending the secret key to the client, so that the client decrypts the to-be-decrypted node according to the secretkey. The safety of the SO library can be improved. 本发明提供种文件处理方法、设备及计算机可读存储介质，涉及数据库技术领域，用以提高SO库的安全性。本发明的文件处理方法，包括：接收客户端发送的待处理SO库的哈希值，其中，在所述待处理SO库中包括待解密节；根据所述哈希值获取对应的密钥；向所述客户端发送所述密钥，以使所述客户端根据所述密钥解密所述待解密节。本发明可提高SO库的安全性。
