What is the relationship between electronic signatures and digital certificates?

An electronic signature, as defined in law, is any data contained in electronic form, attached to which the signatory identifies the signatory and indicates the signatory's approval of its contents; Electronic signatures in the narrow sense are digital signatures.

A digital certificate is an online digital identity certificate issued and managed by an authoritative notarized third-party certification authority (CA) or an enterprise for an individual or enterprise. A digital signature is a signature result that is retained on an electronic document after signing an electronic document with a digital certificate to prove the signatory's willingness to sign. Therefore, digital certificates are the basis of digital signatures, and digital signatures are the application results of digital certificates.

At present, individuals or enterprises can complete the application and acquisition of certificates in the first way through the contract lock, without directly applying to the CA certification body. After the personal or enterprise identity information authentication is completed through the contract lock, the contract lock automatically applies for and obtains the corresponding digital certificate.

A digital certificate is a string of numbers that identifies the identity of all parties to the communication in Internet communication, and a digital signature is an ordinary physical signature similar to that written on paper. A digital certificate is a file that is digitally signed by a certificate authority that contains information about the owner of a public key and a public key. In its simplest form, a certificate contains a public key, a name, and a digital signature from the certificate authority.

Another important feature of digital certificates is that they are only valid for a specific period of time. Digital signature technology encrypts the digest information with the sender's private key and transmits it to the receiver along with the original text. The receiver can only decrypt the encrypted digest information with the sender's public key, and then use the hash function to generate a digest message for the received original text, which is compared with the decrypted digest message.

If it is the same, it means that the information received is complete and has not been modified during transmission, otherwise the message has been modified, so the digital signature can verify the integrity of the information.

A digital certificate (also known as a digital identity) refers to an electronic document issued by a CA organization, which is a string of numbers that can indicate the identity information of a network user and provide a way to verify the identity of a network user on a computer network.

The role of digital certificates: to ensure the confidentiality of information transmission, the integrity of data exchange, the non-repudiation of sent information, and the certainty of trader identity.

The holder of a digital certificate has a pair of public and private keys that can be used to encrypt and decrypt each other. The public key is public and does not need to be kept secret, the recipient of the electronic contract can view the identity of the signer through the decryption of the public key, which is used to verify whether the electronic contract is signed by the signatory, and the private key is held by the certificate holder himself and is used for electronic signature encryption. The electronic contract platform issues digital certificates to users through the CA certification authority, and realizes electronic signatures based on this digital certificate.

The application process for an electronic signature digital certificate is as follows: 1) A copy of the ID card signed by the applicant and submitted to the customer service staff of the registration institution; 2) After receiving the above-mentioned application materials submitted by the certificate applicant, the administrator of the acceptance point will review the applicant's identity, application information and supporting materials according to the identity identification specifications, and if the requirements are not met, the applicant will be informed to fill in again or submit the supporting materials; 3) After the review is passed, the certificate applicant shall pay the relevant fees for applying for the digital certificate according to the requirements; 4) The administrator of the acceptance point makes a digital certificate and puts the certificate medium to the certificate applicant. The role of electronic signatures:

1. Real-name authentication on a third-party electronic platform. Electronic signatures rely on third-party electronic platforms, so before using electronic signatures, enterprises Honghu need to find a suitable and formal third-party electronic platform for real-name authentication. In order to create a real network environment, real-name authentication is a must.

2. Create your own exclusive electronic signature. When enterprise users pass the authentication on the third-party electronic platform, they can create their own exclusive electronic signatures. Each electronic signature is unique to a single person and cannot be reused or reassigned to any other person, so the identity of the individual should be verified before the electronic signature is used, so that it can be legally valid.

3. Use your own electronic signature when signing the contract. Electronic signatures are standardized procedures and scientific methods used to identify the signatory and recognize the content of an electronic data. Therefore, when using electronic signatures, enterprise users must pay attention to whether their contracts are legal and whether they protect their legitimate rights and interests, because electronic signatures cannot be tampered with and have legal effect, and they will take effect when they are signed.

Article 14 of the Electronic Signature Law stipulates that reliable electronic signatures have the same legal effect as handwritten signatures, so when making electronic signatures, you should follow the requirements to protect your legitimate rights and interests.

1. Different definitions.

Electronic authentication is an encryption technology with core e-book (also known as digital certificate) as the core technology, which is based on PKI technology to encrypt, decrypt, digitally sign and digitally verify the information transmitted on the network.

An electronic signature is a piece of data contained in electronic form, attached to which the signatory identifies the signatory and indicates the signatory's approval of its contents. It is the electronic form of the signature of an electronic document through cryptography.

Second, the application scenarios are different.

Electronic authentication is mainly used in the credit security of electronic transactions to ensure the authenticity and reliability of traders in an open network environment. Electronic authentication is the identification of a person or specific information that has not been modified or replaced during transmission. Electronic authentication can be carried out between the parties and can also be identified by a third party.

Electronic signatures are mainly used in online banking, physical banking, e-government, electronic contract signing, telecommunications, bank business halls and other places. Especially with the development of the Internet, online banking adopts identity authentication based on electronic signatures, which is widely used.

To make a simple analogy:

A digital certificate is like your ID card in reality;

A digital signature is like your signature in reality;

An electronic signature is like a bad stamp in reality.

Digital signatures require the use of digital certificates, and electronic signatures use digital signature technology, as well as digital certificates. The electronic signature contains the data of the digital signature and displays the built-in ** (of the stamp) in the document.

Digital certificates. The digital certificate is a string of numbers that mark the identity information of all parties to the communication in Internet communication, providing a way to verify the identity of the communication entity on the Internet.
