Decode and Encode Object Changes

• The DecodeObject and EncodeObject functions were renamed to CryptDecodeObject and CryptEncodeObject.
• The dwFlags parameter was added to CryptDecodeObject.

  The CRYPT_DECODE_NOCOPY_FLAG can be set to enable the nocopy optimization. This optimization, where appropriate, updates the pvStructInfo fields to point to content residing within pbEncoded instead of making a copy of and appending to pvStructInfo. However, when this optimization is used, pbEncoded can't be freed until pvStructInfo is freed.

• The data structures used by CryptEncodeObject and CryptDecodeObject were added and changed.

  At the time of the SDR, there were 13 predefined data structures that could be used with CryptEncodeObject and CryptDecodeObject. We have added eight more.

  The X509_SET_* data structures have been deleted. The X509_SPC_* data structures have been moved to the signcde.h file.

• At the time of the SDR, there were individual encode and decode functions for the first 13 predefined data structures. These functions have been deleted.
• For X509_CERT, the data structure used for encode/decode was changed from CERT_ENCODING to CERT_SIGNED_CONTENT_INFO. The CERT_ENCODING data structure has been deleted.

The following table maps the lpszStructTypes defined at the SDR to the corresponding current data structures:

The following lpszStructTypes have been added:
