Methods

public bool AddCertificate(Cert cert);

Adds a certificate to the store. If the certificate is already in the store, it is updated with the new information.

public bool CreateFileStore(string filename);

Creates a new file-based certificate store. Certificates may be saved to this store by calling AddCertificate.

Returns true for success, false for failure.

public bool CreateMemoryStore();

Creates an in-memory certificate store. Certificates may be added by calling AddCertificate.

Returns true for success, false for failure.

public bool CreateRegistryStore(string regRoot, string regPath);

Creates a registry-based certificate store. regRoot must be "CurrentUser" or "LocalMachine". regPath is a registry path such as "Software/MyApplication/Certificates".

Returns true for success, false for failure.

public Cert FindCertByRfc822Name(string name);

Locates a certificate by its RFC 822 name and returns it if found. Otherwise returns NULL.

public Cert FindCertBySerial(string str);

Finds and returns the certificate that has the matching serial number.

public Cert FindCertBySha1Thumbprint(string str);

Finds a certificate by it's SHA-1 thumbprint. The thumbprint is a hexidecimal string.

public Cert FindCertBySubject(string str);

Finds a certificate where one of the Subject properties (SubjectCN, SubjectE, SubjectO, SubjectOU, SubjectL, SubjectST, SubjectC) matches exactly (but case insensitive) with the passed string. A match in SubjectCN will be tried first, followed by SubjectE, and SubjectO. After that, the first match found in SubjectOU, SubjectL, SubjectST, or SubjectC, but in no guaranteed order, is returned. All matches are case insensitive.

public Cert FindCertBySubjectCN(string str);

Finds a certificate where the SubjectCN property (common name) matches exactly (but case insensitive) with the passed string.

public Cert FindCertBySubjectE(string str);

Finds a certificate where the SubjectE property (email address) matches exactly (but case insensitive) with the passed string. This function differs from FindCertForEmail in that the certificate does not need to match the ForSecureEmail property.

public Cert FindCertBySubjectO(string str);

Finds a certificate where the SubjectO property (organization) matches exactly (but case insensitive) with the passed string.

public Cert FindCertForEmail(string emailAddress);

Finds a certificate that can be used to send secure email to the passed email address. A certificate matches only if the ForSecureEmail property is TRUE, and the email address matches exactly (but case insensitive) with the SubjectE property. Returns NULL if no matches are found.

public Cert GetCertificate(int index);

Returns the Nth certificate in the store. The first certificate is at index 0.

public Cert GetEmailCert(int index);

Returns the Nth email certificate in the store. The first certificate is at index 0. Use the NumEmailCertificates property to get the number of email certificates.

public bool LoadPfxData(byte[] pfxData, string password);

Loads a PFX from an in-memory image of a PFX file.

Returns true for success, false for failure.

public bool LoadPfxFile(string pfxFilename, string password);

Loads a PFX file.

Returns true for success, false for failure.

public bool OpenChilkatStore(bool readOnly);

Opens the registry-based local machine certificate store having the path "Software/Chilkat/SystemCertificates". If the certificate store does not exist, it is automatically created. Set readOnly = true if you are only fetching certificates and not updating the certificate store (i.e. you are not adding or removing certificates). Setting readOnly = true will prevent many "permission denied" errors.

Returns true for success, false for failure.

public bool OpenCurrentUserStore(bool readOnly);

Opens the registry-based current-user certificate store. Set readOnly = true if you are only fetching certificates and not updating the certificate store (i.e. you are not adding or removing certificates). Setting readOnly = true will prevent many "permission denied" errors.

Returns true for success, false for failure.

public bool OpenFileStore(string filename, bool readOnly);

Opens a file-based certificate store.

Returns true for success, false for failure.

public bool OpenOutlookStore(bool readOnly);

Opens the registry-based certificate store used by Outlook. Set readOnly = true if you are only fetching certificates and not updating the certificate store (i.e. you are not adding or removing certificates). Setting readOnly = true will prevent many "permission denied" errors.

Returns true for success, false for failure.

public bool OpenRegistryStore(string regRoot, string regPath, bool readOnly);

Opens an arbitrary registry-based certificate store. regRoot must be "CurrentUser" or "LocalMachine". regPath is a registry path such as "Software/MyApplication/Certificates".

Returns true for success, false for failure.

public bool RemoveCertificate(Cert cert);

Removes the passed certificate from the store. The certificate object passed as the argument can no longer be used once removed.

public bool SaveLastError(string filename);

Saves the last error information to an XML formatted file.
