Our server runs with DH key size of 2048 bits and we are trying to make requests with httparty(https://github.com/jnunemaker/httparty) to a server that uses DH key size of 1024 bits, i want to now for what reason we are getting this error SSL_connect returned=1 errno=0 state=error: dh key too small, it's because different DH key sizes? 🤔
We haven't control of the server who are using DH key size of 1048 bits. I've opened the same issue on httparty https://github.com/jnunemaker/httparty/issues/664, but seems not a problem with httparty and something with OpenSSL. Currently our server is using *OpenSSL 1.1.1c*, but before we was using *OpenSSL 1.1.0j* and this error doesn't happen. Is OpenSSL blocking the communication between our server who uses DH 2048 bits and the other server who uses DH 1024 bits (weak Diffie-Hellman)? If yes, is it reported in somewhere? Our server SSL Labs results: https://www.ssllabs.com/ssltest/analyze.html?d=web.monde.com.br&latest Server who we are trying make requests: https://www.ssllabs.com/ssltest/analyze.html?d=webservices.voeazul.com.br&latest How we can handle with this? I would be happy if anyone can help me with this. :( Att, Marcelo.
