Extracts issuer's distinguished name from X.509 certificate.

VBA/VB6 Syntax


Public Declare Function X509_CertIssuerName Lib "diCrPKI.dll" 
    (ByVal strCertFile As String, ByVal strOutput As String, 
    ByVal nOutChars As Long, ByVal strDelim As String, ByVal nOptions As Long) As Long

nRet = X509_CertIssuerName(strCertFile, strOutput, nOutChars, strDelim, nOptions)

C/C++ Syntax


long __stdcall X509_CertIssuerName(const char *szCertFile, char *szOutput, long nOutChars, const char *szDelim, long nOptions);

Parameters

szCertFile: [in] with the filename of the X.509 certificate (or base64 representation).
szOutput: [out] to receive the name string.
nOutChars: [in] specifying the maximum number of characters to be received.
szDelim: [in] specifying the character to use as a delimiter (default ";").
nOptions: [in] Option flags. Select one of:
PKI_DEFAULT (0) (default)
PKI_X509_LDAP to output the LDAP string representation as per RFC 4514
PKI_X509_LATIN1 to try and convert Unicode/UTF-8/T.61 attribute strings to Latin-1 (8-bit ASCII)

Returns (VBA/C)

Returns the number of characters set in szOutput. If nOutChars is zero it returns the maximum number of characters required. C/C++ users should allocate one extra for the terminating NUL character. If an error occurs, it returns a negative error code.

The output using the PKI_X509_LDAP option is suitable as content for an <X509IssuerName> node in an XML-DSIG document.
