I routinely create self subscribed SSL certs for testing purposes. So I wrote this script to automate this process:
#!/usr/bin/perl
use strict;
use warnings;
use IPC::Run qw(start run);
my $hostname = shift @ARGV;
die "Usage: make_cert HOSTNAME" unless defined $hostname;
{
print "CREATE THE KEY AND REQUEST:\n\n";
my @cmd = qw(openssl req -new -keyout temp.pem -out temp.csr);
my @io = ('Enter PEM pass phrase:',
'test',
'Verifying password - Enter PEM pass phrase:',
'test',
'Country Name.*:',
'UK',
'State.*:',
'Warwickshire',
'Locality Name.*:',
'Kenilworth',
'Organization Name.*:',
'Iponweb Ltd',
'Organizational Unit Name.*:',
'',
'Common Name.*:',
$hostname,
'Email Address.*',
'',
'A challenge password.*:',
'',
'An optional company name.*:',
'');
expect(cmd => \@cmd, io => \@io);
print "\n";
}
{
print "REMOVE THE PASSPHRASE FROM THE KEY:\n\n";
my @cmd = qw(openssl rsa -in temp.pem -out temp.key);
my @io = ('Enter PEM pass phrase:',
'test');
expect(cmd => \@cmd, io => \@io);
print "\n";
}
{
print "CREATE THE KEY AND REQUEST:\n\n";
my @cmd = qw(openssl x509 -in temp.csr -out temp.cert -req -signke
+y temp.key -days 365);
my @io = ();
expect(cmd => \@cmd, io => \@io);
print "\n";
}
{
print "PREPARING FILES:\n\n";
unlink 'temp.csr';
my $cert = $hostname . '.cert';
rename 'temp.cert', $cert;
my $key = $hostname . '.key';
rename 'temp.key', $key;
print "$cert and $key are ready for usage\n\n";
}
sub expect {
my %param = @_;
my @io = @{$param{io}};
my $out;
my $in;
my $h = start($param{cmd}, '<pty<', \$in, '>pty>', \$out);
my $last_length = 0;
while(1) {
my $expected = shift @io;
last unless defined $expected;
my $input = shift @io;
last unless defined $input;
until($out =~ /\G.*$expected/sgc) {
$h->pump;
local $| = 1;
print substr $out, $last_length;
$last_length = length $out;
}
$in .= $input . "\n";
}
$h->finish;
print substr $out, $last_length;
}
