SSL_R_LIBRARY_HAS_NO_CIPHERS error with openssl in eCos

[Tim Hatton]

Hi,
I am trying to use the eCos port of openssl from ftp://ftp.ecoscentric.com/pub/contrib/openssl-1.9.6b.epk and I am running into a very fundamental problem.

When I try to create an SSL context with

                SSL_CTX* ctx=SSL_CTX_new(SSLv3_method());

I get error SSL_R_LIBRARY_HAS_NO_CIPHERS. I have developed code which works on cygwin (albeit with a more current version of openssl) and it works but I seem to fall at the 1st hurdle with the eCos version. Since the error is so basic I'm hoping it is just some extra initialisation I need to do with this older openssl library but I haven't been able to find any information on it yet. If anyone has been down this path before I'd be very grateful for any assistance,
Thanks
Tim

Did you call OpenSSL_add_all_ciphers() beforehand?

Another thing to check is that you actually have the ciphers you need
compiled in. Because some are protected with patents and you need a
licences etc, by default some are not compiled. Once you have got any
necessary license(s) you can then enable the ciphers in you
configuration.

Thanks for the help. It seems that the problem was even simpler than that, just an embarrassing fault on my part.
Thanks anyway,
Tim
