Browser digital certificate application interface specification1 ScopeThis document specifies the browser SM2 digital certificate application interface; describes the definition of functions, data types and parameters of the digital certificate application interface in browsers, that support the application of domestic cryptographic algorithms. This document is applicable to the development, application, testing of browser products, the development of browser applications that support SM2 digital certificates, the testing of secure browser password modules; it can also be used to guide the integration and development of third-party applications calling SM2 digital certificates in different terminal devices.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in the text. Among them, for dated references, only the version corresponding to that date applies to this document; for undated references, the latest version (including all amendments) applies to this document.

It can be divided into personal certificate, agency certificate, device certificate by type; or it can be divided into signature certificate and encryption certificate by purpose. 3.3 Digital signature The result obtained by the signer using the private key to perform cryptographic operations on the signed data. The result can only be verified by the signer's public key and is used to confirm the integrity of the data to be signed, the authenticity of the signer's identity, the non-repudiation of the signature behavior. 3.4 Certificate context A data structure, which is used to store relevant certificate information, including owner information, public key, issuer information, validity period, extended information.4 AbbreviationsThe following abbreviations apply to this document. AIA. Authority Information Access API. Application Programming Interface CRL. Certificate Revocation List5 Overall technical frameworkThe overall technical framework of the browser digital certificate application interface is shown in Figure 1.6 Algorithm identification and data type6.1 Algorithm identification The identification definition of the algorithm used in this document is implemented in accordance with GB/T 33560. 6.4.3 Certificate find attributes 6.4.3.1 Type definition7 Interface function7.1 Overview The algorithm used in this document shall comply with GB/T 33560 in its identification definition; the error code shall comply with the provisions of Appendix A. The browser digital certificate application interface standard mainly consists of the following parts. 7.2 Certificate storage area management interface 7.2.1 Create certificate context Function prototype. 7.2.3 Add certificate to certificate storage Function prototype 7.2.14 Find CRL in the certificate store Function prototype. 7.2.15 Traverse CRL in the certificate store Function prototype. Function description. Traverse CRL in the certificate store. Call this function to obtain the CRL linked list and eventually all CRLs. 7.5 Relationship with other interface specifications For GM/T 0019, its main purpose is to provide general cryptographic services such as certificate parsing, certificate authentication, confidentiality, integrity and non- repudiation of information to the cryptographic service layer and application layer, through a unified cryptographic service interface; GM/T 0118-2022 GM CRYPTOGRAPHIC INDUSTRY STANDARD ICS 35.030 L 80 Browser digital certificate application interface specification Issued on.
