For example, the service scenario may be a scenario in which a user password, personal bank card information, or personal identification card information is data-protected. The function input parameters include encryption type, encryption mode, encryption key, and/or file storage path. Wherein the encryption type includes symmetric encryption, asymmetric encryption, and the like. Encryption modes include 3DES (Triple DES) encryption, SHA1 (Secure Hash Algorithm 1) encryption, and the like. The file storage path refers to a file storage path of encrypted data after data encryption is completed.

The electronic device invokes a data encryption function based on the function input parameters. The data encryption function is obtained by packaging a data encryption function, and the data encryption function characterizes that an SAP system executes an external operating system encryption command to carry out data encryption processing. The external operating system encryption command may be an encryption command of an operating system other than the SAP system, for example, the external operating system encryption command may be an OpenSSL encryption command. OpenSSL is an open-source product to implement the SSL protocol, which implements most of the algorithms required for the SSL protocol. Therefore, the data is encrypted by using an encryption algorithm supported by OpenSSL, and the encrypted data can be decrypted by other operating systems except the SAP system, so that the method has universality. The invention can realize the encryption processing of the SAP system to the data by using the encryption command of the external operating system supported by OpenSSL, and the encryption command of the external operating system has universality and is not limited by the SAP system any more during decryption.

The electronic equipment performs data encryption processing on the SAP system by executing an external operating system encryption command based on the data encryption function based on the encryption type, the encryption mode, the encryption key and the file storage path determined in the function input parameters, and obtains encrypted data. For example, when the encryption type determined in the function input parameter is symmetric encryption and the encryption mode is 3DES encryption, the data encryption processing is performed by executing an external operating system encryption command on the SAP system based on the symmetric encryption and the 3DES encryption, and the encrypted data is stored in the file storage path determined in the function input parameter.
