这是几个用来签发证书的脚本，请注意这需要你安装了gnutls才可以，主要当时是为了ocserv而写，纯偷懒。基本上，你只要用 ./cert-client.sh you-user-name 这种格式，就可以自动生成 you-user-name-key.pem/ your-user-name-cert.pem /your-user-name.p12

cert-client.sh

#! /bin/sh
#! /usr/bin/expect -f


certtool --generate-privkey --outfile $1-key.pem
sed -i "1ccn = "${1}"" client.tmpl
sed -i "3cemail = ${1}@abc.org" client.tmpl
certtool --generate-certificate --load-privkey $1-key.pem --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem --template client.tmpl --outfile $1-cert.pem
openssl pkcs12 -export -inkey $1-key.pem -in $1-cert.pem -name "$1 VPN Client Cert" -certfile ca-cert.pem -out $1.cert.p12



exit 0
