Connection Error [SSL: DH_KEY_TOO_SMALL] dh key too small (_ssl.c:1056) #64

Getting this error when I run python3 ./getpassword.py.

Connection Error [SSL: DH_KEY_TOO_SMALL] dh key too small (_ssl.c:1056)

It can find my roomba and gives back a blid. The password field stays empty though.

Might need just a tad more information.. OS? Debian just increased their default SSL security requirement which causes this error.

Can you post the full output?

I'm using Hasbian, so I guess it might be related to the issue you mention. Is there a way for me to address this? Thank you for the fast response.

I'm trying to find out what version of password.py you re using, 2.5 is the latest and has some changes to the way TLS is done, you're cutting off the version level output.

As to workaround, you can lower the SSL secutity level to 1 by editing /etc/ssl/openssl.conf and entering:

CipherString=DEFAULT@SECLEVEL=1

I have pushed a potential fix. V1.2.6 - try it and let me know what happens.

Works like a charm! Thanks a lot.
