Hi,
I am searching for a certificate by the MD5-hashed public
key, but it isn't finding the certificate. Should I be
creating an MD5 hash of the Public Key Info or of some
other Public Key data?
This is what I am doing:
When creating the MD5-hash, I get the CERT_PUBLIC_KEY_INFO
from the certificate. I then call CryptHashPublicKeyInfo
to create an MD5 hash of this Public Key Info.
At the end that has to search for the certificate, I read
in this MD5-Hash and store to a CRYPT_HASH_BLOB. I then
call CertFindCertificateInStore passing in the
CRYPT_HASH_BLOB and use the CERT_FIND_PUBKEY_MD5_HASH flag.
Thanks,
Craig.
