szOID_NETSCAPE_COMMENT

For the szOID_NETSCAPE_COMMENT extension, CryptEncodeObject, CryptEncodeObjectEx, CryptDecodeObject, or CryptDecodeObjectEx can be called with lpszStructType set to X509_ANY_STRING or X509_UNICODE_ANY_STRING.

It is a comment that may be displayed to the user when the certificate is viewed.

The following details apply:

Object Identifier String

"2.16.840.1.113730.1.13"

Corresponding Data Structure being encoded or decoded

pvStructInfo points to a CERT_NAME_VALUE structure. The dwValueType member of the CERT_NAME_VALUE is set to CERT_RDN_IA5_STRING. The Value member's pbData member points to an IA5_STRING that is a comment that may be displayed to the user when the certificate is viewed.

Additional Details

When encoding, use X509_ANY_STRING when the string format in the Value member's pbData member is Ascii, and use X509_UNICODE_ANY_STRING when the string format is UNICODE. For the UNICODE case, before encoding, the string is converted to an IA5_STRING as specified by setting dwValueType to CERT_RDN_IA5_STRING.

For decoding, the user has the option of selecting the format of the string that is output to the CERT_NAME_VALUE structure. Use X509_ANY_STRING when the desired string format is Ascii, and use X509_UNICODE_ANY_STRING when the desired string format is UNICODE.
