In an embodiment, the electronic signing request further includes identification information and a signing type identifier of the electronic signing user, the identification information is a handwritten signature of the user, in other embodiments, the identification information may also be privacy information of the user, such as a signature, a fingerprint, a voice, an iris, and the like, the signing type identifier is specifically a contract template ID, different signing type identifiers correspond to different contract templates, the contract template ID corresponds to a corresponding contract template stored on the file server, and the contract template ID is for distinguishing various different contract templates.
In this embodiment, the electronic contract is applied to the credit contract and credit investigation contract signing in the vehicle insurance separate period, the corresponding contract template ID is CX001, in the other embodiment, the electronic contract is also applied to the credit contract and credit investigation contract signing in the house loan separate period, the corresponding contract template ID is FD001, and the corresponding contract template texts with the contract template IDs of CD001, FD001, and the like are stored in the file server.
The contract template corresponding to the template ID is a html-format file generated according to the needs of a fund party, and the template comprises a plurality of key fields, such as loan start and end dates, loan purposes, customer signatures, dates and other fields which are set to be blank.
Step S200: receiving an encryption trigger signal of a user side, and encrypting the electronic signing information to obtain an encrypted electronic signing information packet;
the electronic signing information also comprises information filled by a user based on a contract template, in the embodiment, the electronic signing information comprises information such as loan start and end dates, loan amount, loan application, customer signature, loan date and the like, and the encrypted electronic signing information comprises encrypted electronic signing information, signature data and an encryption key.

In an exemplary embodiment, referring to fig. 2, step S200 may further include:
step S201: calling an encryption interface, wherein an encryption application program used for encrypting the electronic subscription information is stored in the encryption interface;
in one embodiment, the encryption interface is a meter interface. And exporting the encrypted code and storing the encrypted code as a jar packet to form an encrypted application program, and putting the encrypted application program and the dependent file into a lib/ext of a folder corresponding to the jmeter interface together for convenient management.

Specifically, through the program flow, four 32-bit data are generated and finally combined to form a 128-bits hash.
The basic encryption mode is to obtain the result by performing cyclic operation on the remainder, the length adjustment and the link variable.
F(X,Y,Z)=(X∧Y)∨(﹁X∧Z)
G(X,Y,Z)=(X∧Z)∨(Y∧﹁Z)
H(X,Y,Z)=X⊕Y⊕Z
I(X,Y,Z)=Y⊕(X∨﹁Z)

in an exemplary embodiment, referring to fig. 4, step S202B may further include:
step S202B 1: encrypting the encrypted electronic signing information by using a first symmetric key to obtain a first electronic signing information packet to be signed;
specifically, the symmetric key means that two parties of information transmission use the same key to encrypt and decrypt, and symmetric encryption has many algorithms, and because of its high efficiency, it is widely used in the core of many encryption protocols. Symmetric encryption typically uses relatively small keys, typically less than 256 bits. Because the larger the key, the stronger the encryption, but the slower the process of encryption and decryption. The size of the key takes care of both security and efficiency. The server controls the user side to encrypt the encrypted electronic signing information by adopting the first symmetric key so as to obtain a first electronic signing information packet to be signed, and the security of data transmission is improved.

specifically, a signature algorithm is adopted to sign the first electronic signing information packet to be signed so as to prevent the electronic signing information from being tampered in the transmission process.
Generally, the signature is performed using MD5 (message digest algorithm), SHA (secure sequence algorithm), or the like. In this embodiment, the first electronic subscription package to be signed is signed by using the SHA algorithm.
Step S202B 3: asymmetrically encrypting the first electronic signing information packet to be encrypted by using a first preset public key to obtain a first encrypted electronic signing information packet, wherein the first preset public key and a first preset private key in the server form a pair of first asymmetric keys;
in particular, asymmetric encryption uses a pair of keys, a public key and a private key. The private key can only be safely kept by one party and cannot be leaked out, while the public key can be sent to any person who requests it. Asymmetric encryption uses one of the pair of keys for encryption, while decryption requires the other key. While asymmetric encryption is very secure, it is very slow compared to symmetric encryption.
The method comprises the steps of storing a set of first asymmetric secret keys in a user side and a server corresponding to the user side in advance, wherein a first public key of the first asymmetric secret key is preset in a signing security control or a signing security digital certificate of the user side, a first private key of the first asymmetric secret key is arranged in the server, and a first electronic signing information packet to be encrypted is encrypted by the first public key to obtain a first encrypted electronic signing information packet.

specifically, the server controls the user side to encrypt the first encrypted electronic subscription information packet by using the second symmetric key so as to obtain a second electronic subscription information packet to be encrypted, and the security of data transmission is improved.
Step S202C 2: signing the second electronic signing information packet to be signed by adopting a signature algorithm to obtain a second electronic signing information packet to be encrypted;
specifically, a signature algorithm is adopted to sign the second electronic signing information packet to be encrypted so as to prevent the electronic signing information from being tampered in the transmission process.
Step S202C 3: and asymmetrically encrypting the second electronic signing information packet to be encrypted by using a second preset public key to obtain a second encrypted electronic signing information packet, wherein the second preset public key and a second preset private key in the server form a pair of second asymmetric keys.
Specifically, a set of second asymmetric keys is stored in the user side and the server corresponding to the user side in advance, wherein a second public key of the second asymmetric key is preset in a subscription security control or a subscription security digital certificate of the user side, a second private key of the second asymmetric key is arranged in the server, and the second public key is used for encrypting the second electronic subscription information packet to be encrypted to obtain a second encrypted electronic subscription information packet. Correspondingly, the server is able to decrypt the second public key using the second private key.
Step S300: decrypting the encrypted electronic signing information packet sent by the user side to obtain decrypted electronic signing information;
in an exemplary embodiment, referring to fig. 6, step S300 may further include:

step S3013: if the verification is passed, decrypting the second signature electronic signing information packet by adopting a second symmetric key to obtain a first encrypted electronic signing information packet;
specifically, the server receives a second encrypted electronic subscription information packet sent by the user side, first obtains a second electronic subscription information packet to be encrypted through a second private key stored in the server, then verifies first signature data of the second electronic subscription information packet to be encrypted by adopting a verification algorithm, and if the verification is passed and the first encrypted electronic subscription information packet is proved not to be tampered in the transmission process, decrypts the second signed electronic subscription information packet by using a second symmetric key to obtain the first encrypted electronic subscription information packet.
Step S302: decrypting the first encrypted electronic signing information packet to obtain the encrypted electronic signing information;
in an exemplary embodiment, referring to fig. 8, step S302 may further include:
step S3021: decrypting the first encrypted electronic signing information packet by using a first preset private key to obtain a first electronic signing information packet to be encrypted;

Step S402: acquiring a file template corresponding to the signing type identifier according to the signing type identifier;
specifically, according to the contract template ID, a corresponding contract document template is obtained, for example, the contract template corresponding to the FD001 is a house loan template.
Step S403: and filling the signing content information into the corresponding file template to generate a signing file.
Specifically, the server fills the content of the electronic subscription information into the corresponding position to generate the subscription file.

Specifically, in an embodiment, before sending the electronic subscription request to the user side, a verification request may be initiated to the user, where the request may be whether to sign a subscription, when a preset instruction sent by the user side is received within a preset time, the electronic subscription request is initiated through verification, and when the preset instruction is not received within the preset time, the electronic subscription request is not initiated. In this embodiment, the preset instruction may be preset, and may be "yes" or "no", and may also be represented by another identifier, for example, a number "1" or "0", an english letter "Y" or "N", and the present solution is not limited herein.
Step S500: and storing the signing file to a corresponding position of a file server.
Specifically, the generated subscription file is stored in a corresponding position in the file server by a preset path, which is convenient for reference.
