Hi,
dma currently use the TLSv1_client_method() function that means that it
only support TLS 1.0 which is considered deprecated (and forbidden by
PCI certification).
For what I can read, major providers are planning to remove support for
TLS 1.0 and TLS 1.1 current 2020.
The attached patches (cherry-picked from upstream) are switching to the
"version-flexible" function (TLS_client_method())
Could this be included in buster?
Kind regards,
Laurent Bigonville
