We have an issue with being unable to negotiate encryption keys with one of our data partners.
From the error message and my research, it looks like a problem between old, deprecated DSA encryption and SHA1 versus SHA256 for RSA,
and the only solution is to upgrade to a newer version of curl.
The problem is that we run on AIX, so we cannot simply pull an RPM for a Linux distro. I tried to investigate the curl releases documentation,
but I cannot tell when SHA256 support was added.
Could someone with more knowledge please let me know when SHA256 support was added?
Thanks.
