Client
Create a new key
$ openssl genrsa -aes256 -out 0x20-vpn-your_name_here.key 2048
Create a Certificate signing request
$ openssl req -new -key 0x20-vpn-your_name_here.key -out 0x20-vpn-your_name_here.csr
countryName = BE
stateOrProvinceName = Ghent
organizationName = 0x20
organizationalUnitName = members
commonName = your_name_here
Get your certificate signed
Mail your CSR(certificate signing request) to someone who has access to the 0x20 CA. Best is being physically present in the space.
Sign cert:
$ openssl ca -in ../0x20-vpn-your_name_here.csr -cert ca-0x20-cert.pem -keyfile private/ca-0x20-key.pem -out 0x20-vpn-your_name_here.cert -config ./openssl.cnf
