Hello,
I'm trying to verify an x509 certificate with a custom library (other than
openssl)
The reason I'm writing to this mailing list is that I can't figure out what
is going wrong.
The library is checked and nothing is wrong so I must be missing something.
The program I'm writing has to be
The certificate is received in ASN.1 DER format. Not PEM.
The only thing I want to do is verify the signature of the certificate, and
thus verify the signature itself.
It is self-signed so the public key in the certificate should be used to
verify the signature, but it isn't working.
Certificate:

Thank you all for the help.

Hello,
Is there an easy way in OpenSSL to call some function which returns the
length of the digest/hash it returns? Like SHA256 would return 32 (maximum
digest length of 32 bytes).

Can someone tell me what hash algorithm the RSA_public_encrypt function
uses?
Is this SHA1 only for both?

. This mode is recommended for all new applications.

How do you use EVP_MD_size() if the only thing you have is the NID of the
algorithm?

There is currently a parsing bug when converting from PEM to DER.
I encountered this as well, but with DSA keys.
I suppose the same bug occurs with RSA keys.
In DSA the G component gets copied to the pub component when converting
from PEM to DER.
From DER to PEM works fine.

Dereck
