The following functions support the MakeCert tool. Certificates are verified using CTLs or certificate chains.

Functions are provided for both of these:. These functions use CTLs in the verification process. CryptoAPI message functions consist of two groups of functions: low-level message functions and simplified message functions.

Low-level message functions create and work directly with PKCS 7 messages. They also decrypt and verify the signatures of received messages. Simplified message functions are at a higher level and wrap several low-level message functions and certificate functions into single functions that perform a specific task in a specific manner. These functions reduce the number of function calls needed to accomplish a task, thereby simplifying CryptoAPI use. For an overview of simplified messages, see Simplified Messages.

Low-level message functions provide the functionality necessary to encode data for transmission and to decode PKCS 7 messages received. Functionality is also provided to decrypt and verify the signatures of received messages. Use of these low-level message functions in most applications is not recommended. For most applications, the use of Simplified Message Functions, which wrap several low-level message functions into a single function call, is preferred. The EKU extension and extended property specify and limit the valid uses of a certificate.

The extensions are part of the certificate itself. They are set by the issuer of the certificate and are read-only. Certificate-extended properties are values associated with a certificate that can be set in an application.

Key identifier functions allow the user to create, set, retrieve, or locate a key identifier or its properties. The key identifier allows the use of that key pair to encrypt or decrypt messages without using the certificate. A key identifier can have the same properties as a certificate context. For more information, see CertCreateContext. These functions provide object identifier OID support. These functions install, register, and dispatch to OID and encoding type-specific functions.

Certificate Services includes functions for backing up and restoring the Certificate Services database. These Certificate Services backup and restore functions are contained in Certadm. Unlike the other API elements associated with Certificate Services, these functions are not encapsulated in an object that can be used to call class methods. Instead, the backup and restore APIs are called by first loading the Certadm. When you have finished calling the Certificate Services backup and restore functions, call FreeLibrary to free Certadm.

Backup and restore functions provided by Certadm. To call the backup and restore functions, you must have backup and restore privileges. For details, see Setting the Backup and Restore Privileges. However, when you create your program, use Certsrv. The callback functions in this section are used to register or install application-defined certificate store providers and to provide related functionality through callback functions.

Callback functions are implemented by an application and are called by CryptoAPI functions. Callback functions enable the application to control, in part, the way that CryptoAPI functions manipulate data. These functions are used to create a catalog.

All of these functions are called by MakeCat. The following callback functions can be implemented by a custom provider that is intended to be called by the Secure Channel Schannel security package to retrieve certificates.

This function applies transforms before updating the digest. Encodes SignatureMethod or DigestMethod elements for agile algorithms with default parameters. Opens an XML digital signature to encode and returns a handle of the opened Signature element. The document context can include one or more Signature elements. Time stamps the specified subject. This function supports Authenticode time stamping. To perform X. This function can be used to perform X. Important] This API is deprecated.

Microsoft may remove this API in future releases. Acquires a handle to the current user's key container within a particular CSP.

Enumerates the providers on a computer. Enumerates the types of providers supported on the computer. Determines the default CSP either for the current user or for the computer for a specified provider type.

Retrieves the parameters that govern the operations of a CSP. Releases the handle acquired by the CryptAcquireContext function. Specifies attributes of a CSP. Removes a default context previously installed by CryptInstallDefaultContext. Creates a key derived from a password. Destroys a key. Makes an exact copy of a key, including the state of the key.
