commit 93f5fda134a2a010b84ffedbe833d670e63ba4be
Author: Christos Tsantilas <christos@chtsanti.net>
Date: 2020-05-15 04:54:54 +0000
Fix sending of unknown validation errors to cert. validator (#633)
Squid may be compiled with an OpenSSL release introducing X509
validation errors that Squid does not have the names for. Send their
integer codes.
Also sync Squid certificate verification errors with OpenSSL v1.1.1g.
This is a Measurement Factory project.
