OpenVPN easy-rsa build-key automation?

Solution 1:

try --batch flag

./build-key --batch client1

Solution 2:

If you look at the source of build-key, you'll find it's calling pkitool. I wrote a wrapper to bundle up the cilent's keys and the appropriate openvpn config files into a tarball I could then give to my users:

#!/bin/bash

client=$1

if [ x$client = x ]; then
    echo "Usage: $0 clientname"
    exit 1
fi

if [ ! -e keys/$client.key ]; then
    echo "Generating keys..."
    . vars
    ./pkitool $client
    echo "...keys generated." 
fi

tarball=./keys/$client.tgz

if [ ! -e $tarball ]; then
    echo "Creating tarball..."
    tmpdir=/tmp/client-tar.$$
    mkdir $tmpdir
    cp company.ovpn $tmpdir/company.ovpn
    cp keys/ca.crt $tmpdir 
    cp keys/$client.key $tmpdir/client.key
    cp keys/$client.crt $tmpdir/client.crt
    tar -C $tmpdir -czvf $tarball .
    rm -rf $tmpdir
    echo "...tarball created" 
else
    echo "Nothing to do, so nothing done. (keys/$client.tgz already exists)" 
fi

Solution 3:

The new version of EasyRSA comes as a single binary right now. To automate building a client key, you can now use "vars" file (just place it in the same directory as easyrsa binary):

if [ -z "$EASYRSA_CALLER" ]; then
    echo "You appear to be sourcing an Easy-RSA 'vars' file." >&2
    echo "This is no longer necessary and is disallowed. See the section called" >&2
    echo "'How to use this file' near the top comments for more details." >&2
    return 1
fi

set_var EASYRSA        "$PWD"
set_var EASYRSA_OPENSSL        "openssl"
set_var EASYRSA_PKI            "$EASYRSA/pki"
set_var EASYRSA_DN     "org"

set_var EASYRSA_REQ_COUNTRY    "Country"
set_var EASYRSA_REQ_PROVINCE   "Province"
set_var EASYRSA_REQ_CITY       "City"
set_var EASYRSA_REQ_ORG        "Org Ltd"
set_var EASYRSA_REQ_EMAIL      "[email protected]"
set_var EASYRSA_REQ_OU         "Infrastructure"

set_var EASYRSA_KEY_SIZE       2048

set_var EASYRSA_ALGO           rsa

set_var EASYRSA_CA_EXPIRE      3650
set_var EASYRSA_CERT_EXPIRE    365
set_var EASYRSA_CRL_DAYS       180

set_var EASYRSA_TEMP_FILE      "$EASYRSA_PKI/extensions.temp"

and use EasyRSA's binary:

./easyrsa build-client-full client1 nopass

Solution 4:

The thing that comes to my mind the quickest is expect; it allows you to automate these sorts of command line interactions.

Solution 5:

I had the same problem.

The solution I found was :

echo -en "\n\n\n\n\n\n\n\ny\ny\n" | ./build-key client1
