Verifies the signature in a pkcs-12 file.
Public Declare Function PFX_VerifySig Lib "diCrPKI.dll"

ByVal nOptions As Long) As Long

If successful, the return value is zero; otherwise it returns a nonzero error code.

Just checks that the MacData signature is OK using the given password. Makes no other checks. The PFX file can be in either BER-encoded binary or PEM format. You can also pass the data directly as a PEM string in the szPfxFile parameter.
[New in v3.8] If there is no MacData signature in the PFX file and the supplied szPassword is empty, it will consider that to be a "valid" signature and return zero.
See the example for PFX_MakeFile above.
