CertFindCertificateInStore This function finds the first or next certificate context in a certificate store that matches search criteria established by the dwFindType parameter and its associated pvFindPara parameter.
CertFindExtension This function finds the first extension in the CERT_EXTENSION array, as identified by its object identifier (OID).
CertFindRDNAttr This function finds the first relative distinguished name (RDN) attribute identified by its object identifier (OID) in an RDN list.
CertFreeCertificateChain This function frees a certificate chain by reducing its reference count.
CertFreeCertificateContext This function frees a certificate context by decrementing its reference count.
CertGetCertificateChain This function builds a certificate chain context starting from an end certificate and going back, if possible, to a trusted root certificate.

CertGetPublicKeyLength This function acquires the bit length of public/private keys from a public key BLOB.
CertGetStoreProperty This function retrieves a store property.
CertGetSubjectCertificateFromStore This function returns from a certificate store a subject certificate context uniquely identified by its issuer and serial number.
CertIsRDNAttrsInCertificateName This function compares the attributes in the certificate name with the specified CERT_RDN structure to determine whether all attributes are included there.
CertNameToStr This function converts the name in a CERT_NAME_BLOB structure to a NULL-terminated character string.

CertOpenStore This function opens a certificate store using a specified store provider type.
CertOpenSystemStore This function is a simplified function used to open the most common system certificate store.
CertRDNValueToStr This function converts a name in a CERT_RDN_VALUE_BLOB structure to a NULL-terminated character string.
CertRemoveEnhancedKeyUsageIdentifier This function removes a usage identifier OID from the certificate's extended key usage (EKU) property.
CertSaveStore This function saves the certificate store to a file or to a memory BLOB.
CertSerializeCertificateStoreElement This function serializes a certificate context's encoded certificate and its encoded properties.
CertSetCertificateContextProperty This function sets an extended property for a specified certificate context.
CertSetEnhancedKeyUsage This function sets the extended key usage (EKU) property for the certificate.
CertSetStoreProperty This function sets a store property.
CertStrToName This function converts a NULL-terminated X500 string to an encoded certificate name.
CertVerifySubjectCertificateContext This function performs the enabled verification checks on a certificate by checking the validity of the certificate's issuer.
CertVerifyTimeValidity This function verifies the time validity of a certificate.
CertVerifyValidityNesting This function verifies that a subject certificate's time validity nests correctly within its issuer's time validity.
CryptAcquireCertificatePrivateKey This function acquires a HCRYPTPROV cryptographic service provider (CSP) handle including access to its related key container and the dwKeySpec parameter for a user's specified certificate context.
CryptCreateKeyIdentifierFromCSP This function creates a key identifier from a cryptographic service provider (CSP) public key BLOB.
