The "d2i" in the function you're trying to use means "from DER encoded to
internal", you'll see a whole lot of complementary functions with "i2d" in them
that do the opposite.
The data you've shown looks like it has been PEM encoded, not DER encoded:

To convert the PEM encoding, try wrap your buffer in a BIO and call
PEM_read_bio_X509(). "man PEM_read_bio_X509" for details. Make sure you
preserve the "-----" bars before and after the PEM encoded certificate, as they
form part of the PEM encoding and your data may be ignored if you chop them off.
