Data encryption and decryption method, device and equipment

The embodiment of the invention discloses a data encryption and decryption method, device and equipment. The data encryption method comprises the following steps: acquiring at least one to-be-encrypted file transmitted by a client; for each to-be-encrypted file, identifying sensitive data in the to-be-encrypted file; encrypting the sensitive data to obtain an encrypted file corresponding to the to-be-encrypted file; and sending the encrypted file to the client. According to the data encryption and decryption method, device and equipment provided by the embodiment of the invention, data encryption and data decryption are not carried out in the client, and the secret key is not sent to the client, so that the secret key can be prevented from being leaked, and the data security is improved. 本发明实施例公开了一种数据加密、解密方法、装置及设备。数据加密方法包括：获取客户端传输的至少一个待加密文件；针对每一个待加密文件，识别待加密文件中的敏感数据；对敏感数据进行加密，得到待加密文件对应的加密文件；将加密文件发送给客户端。本发明实施例的数据加密、解密方法、装置及设备，没有在客户端中进行数据加密和数据解密，也没有将密钥发送给客户端，能够防止密钥泄露，提高数据安全性。
