Jun 25, 2017 · Posted November 18, 2019 By afkpaul. Hello, Something changed on openssl-1.1.0j regarding MD5 (they disabled support by default) So it needs to be enabled. I’ve added line Environment=“OPENSSLENABLEMD5VERIFY=1 NSSHASHALGSUPPORT=+MD5” under [Service] section in file openvpn@.service
CA-Signed Certificate: A certificate authority (CA) electronically signs a certificate to affirm that a public key belongs to the owner named in the certificate. Someone receiving a signed certificate can verify that the signature does belong to the CA, and determine whether anyone tampered with the certificate after the CA signed it. Step 4 – Create Self-Signed Certificate for the Certificate Authority. Execute the following command to generate the new self-signed certificate for the certificate authority: openssl req -new -x509 -days 3650 -key ca.key -out ca.crt. The -x509 option outputs a self-signed certificate instead of a certificate request.

It works the same as a normal SSL certificate with one major difference. Standard SSL certificates are issued and verified by a trusted Certificate Authority (CA).
This makes sense: if OpenSSL no longer accepts the peer certificate to be equal to the supplied CA certificate (which actually is the server cert), it will try to traverse the chain supplied by the server, and end up at the real CA cert, which is indeed self-signed. Problem solved, case closed. Thanks eworm!
Verify return code: 27 (certificate not trusted) Basically this is telling me that there is a problem with the certificates.
