OpenSSL 1.1 does not allow certificates with MD5 hashes anymore.

Yeah... I need change certificates on 400 devices.

Get version 0.6.72:

  • WARNING: OpenSSL 1.1.0f does not accept MD5 certificates by default anymore, upgrade your certificates or use tls-cipher "DEFAULT:@SECLEVEL=0" as custom option to workaround the problem.

Btw. MD5 is really weak and collisions can be created in a number of hours, so it is not safe at any level anymore.

Could you give some example for using tls-cipher "DEFAULT:@seclevel=0" in ovpn config? I can't find it.

I am not sure what you asking for? You just have to add that line to the config file or as custom option.

I want to try, but when I added to custom options it isn't working. Now I create new certificates and change on devices.

The options definitively works, I tested it myself.

OK . I won't use. New certs are safer.
