67 For a certificate "www.example.com.pem"
68 signed by "signing.example.net.pem"
69 signed by root CA "ca.example.net.pem"
70 with OCSP server http://ocsp.example.net/
72 Ensure there is a file with the signing chain
74 cat ca.example.net.pem signing.example.net.pem >chain.pem
76 The update procedure would be
78 ocsp_fetch -i signing.example.net.pem \
79 -c www.example.com.pem \
80 -u http://ocsp.example.net/ \
82 -o www.example.com.ocsp.der
