To whom it may concern,
 
I am trying now for several days to import a certificate, to process it in my C++ code. What am I doing wrong? Here are the steps I perform in my code:
 
I initiate with gnutls_global_init();
I get a FILE-type opject into my programm, using fopen and fread
I save the FILE-type obejct containing the certificate and the length of the FILE-type into a gnutls_datum_t-type object (loaded_file)
I init a gnutls certificate with gnutls_x509_crt_init(&cert)
I use gnutls_x509_crt_import(cert, &loaded_file, GNUTLS_X509_FMT_PEM)
 
I get the error code -207: Base64 unexpected header error...what does this mean?
when I want to print the certificate information using gnutls_x509_crt_print() I get the following information:
--------------------------------------------------------------------------------
cert[1424]:
 X.509 Certificate Information:
    Version: 1
error: get_serial: ASN1 parser: Value was not found.
    Issuer:
    Validity:
        Not Before: Wed Dec 31 23:59:59 UTC 1969
        Not After: Wed Dec 31 23:59:59 UTC 1969
    Subject:
error: get_signature_algorithm: ASN1 parser: Value was not found.
warning: signed using a broken signature algorithm that can be forged.
error: get_signature: ASN1 parser: Value was not found.
Other Information:
error: get_fingerprint: ASN1 parser: Value was not found.
error: get_key_id: ASN1 parser: Value was not found.
---------------------------------------------------------------------------------
The certificate I am trying to import is a selfsigned certificate created with certtool.
 
what is wrong in my import-chain?
 
Thank you very much for your help.
 
 
Regards ,
Maximilian
