[Help-gnutls] Re: ex-client-srp and ex-serv-srp

[Simon Josefsson]

The error message is a bit sub-optimal, I think you'll get this error if
there a problem with the credentials (e.g., the file is in the wrong
directory, cannot be read, or bad format or similar).  The reasons for
why that happens is a long story, and probably the examples could be
improved here..

Btw, was it difficult to build the examples using VS?  Are you using the
official GnuTLS DLL, or did you build GnuTLS from source too?
