It doesn't correspond to any actual standard, and since it drops the
initial sequence header, won't be recognized by the Crypto API.
The assumption here is that CertFindCertificateInStore() will allow any
appropriate variations in the encoding when it does its comparison.
This is, however, emphatically not true under Wine, which just compares
the encodings with memcmp().
Most of the time things work anyway, though, and there isn't really
anything we can do to make the situation better.
[1] A "canonical form" is defined as the one where, if you locked 10
mathematicians in a room and asked them to come up with a
representation for something, it's the answer that 9 of them would
give you back.
I don't think OpenSSL's encoding qualifies.*/
