how to send arbitrary data in supplemental data message

[LATZE Carolin]

Hi everybody,

I ran again into problems with the supplemental data messages. I tried to copy a certificate into the buffer of type gnutls_buffer and do not manage to send all 1314 bytes of the certificate. Instead it sends only 41 bytes. I tried it with another certificate which resulted in 65 bytes sent. This is pretty strange. I expected the buffer to stop at a \0 character in the signature, but that does not seem to be the case since strlen of the original data results in the correct length of 1314. Any ideas?

In order to simplify debugging, I copied my gnutls version including the tls-tpm extension (not finished yet, but does not cause crashes :-)) onto a server:

Furthermore, I uploaded my little sample program as well:

I would be happy for any hints or ideas since I am clueless at the moment.
