You'll need to use the higher-level API in <Security/
SecImportExport.h> for this; there is no support for PKCS12 at the
CDSA level.

Hi,
Does anyone know of a way to extract private keys from PFX or
PKCS#12 formats using the CDSA/CSSM API?
The only data structure I've found that seems to be related is the
CSSM_CERT_BUNDLE. If I construct one from scratch, set the
encoding, and set the CSSM_DATA equal to the PFX/PKCS data, I
assume that I could set the type equal to either
CSSM_CERT_BUNDLE_PFX or CSSM_CERT_BUNDLE_PKCS12 and have it be valid.
From there, it appears I could use
CSSM_CL_CertGroupFromVerifiedBundle to convert it into a
CSSM_CERTGROUP, but I'm not sure where to go from that point
because there still doesn't seem to be a way to extract the
private key when it's in either the CSSM_CERT_BUNDLE or
CSSM_CERTGROUP format.
If anyone can provide any insight into this issue, I would
appreciate it. Please let me know.
Thanks,
- Eric P.
