[openssl-users] X509 subject key identifier

How can I programmatically get the Subject Key Identifier as a byte
array from an X509 certificate.
(Just to show that I tried before posting)
I would like the output as a byte array, not text, so tracing the
X509_print_fp() gave clues but not an answer.
I have the general sense that it's within x509->cert_info_extensions,
and that I use NID_subject_key_identifier to extract an extension from
the stack. Then I perhaps get the ASN1 object from the extension and
from there the value.
