#!/usr/bin/perl # # CA - wrapper around ca to make it easier to use ... basically ca requires # some setup stuff to be done before you can use it and this makes # things easier between now and when Eric is convinced to fix it :-) # # CA -newca ... will setup the right stuff # CA -newreq[-nodes] ... will generate a certificate request # CA -sign ... will sign the generated request and output # # At the end of that grab newreq.pem and newcert.pem (one has the key # and the other the certificate) and cat them together and that is what # you want/need ... I'll make even this a little cleaner later. # # # 12-Jan-96 tjh Added more things ... including CA -signcert which # converts a certificate to a request and then signs it. # 10-Jan-96 eay Fixed a few more bugs and added the SSLEAY_CONFIG # environment variable so this can be driven from # a script. # 25-Jul-96 eay Cleaned up filenames some more. # 11-Jun-96 eay Fixed a few filename missmatches. # 03-May-96 eay Modified to use 'ssleay cmd' instead of 'cmd'. # 18-Apr-96 tjh Original hacking # # Tim Hudson # tjh@cryptsoft.com # # 27-Apr-98 snh Translation into perl, fix existing CA bug. # # # Steve Henson # shenson@bigfoot.com # default openssl.cnf file has setup as per the following # demoCA ... where everything is stored my $openssl; if(defined $ENV{OPENSSL}) { $openssl = $ENV{OPENSSL}; } else { $openssl = "openssl"; $ENV{OPENSSL} = $openssl; } $SSLEAY_CONFIG=$ENV{"SSLEAY_CONFIG"}; $DAYS="-days 365"; # 1 year $CADAYS="-days 1095"; # 3 years $REQ="$openssl req $SSLEAY_CONFIG"; $CA="$openssl ca $SSLEAY_CONFIG"; $VERIFY="$openssl verify"; $X509="$openssl x509"; $PKCS12="$openssl pkcs12"; $CATOP="./demoCA"; $CAKEY="cakey.pem"; $CAREQ="careq.pem"; $CACERT="cacert.pem"; $DIRMODE = 0777; $RET = 0; foreach (@ARGV) { if ( /^(-\?|-h|-help)$/ ) { print STDERR "usage: CA -newcert|-newreq|-newreq-nodes|-newca|-sign|-verify\n"; exit 0; } elsif (/^-newcert$/) { # create a certificate system ("$REQ -new -x509 -keyout newkey.pem -out newcert.pem $DAYS"); $RET=$?; print "Certificate is in newcert.pem, private key is in newkey.pem\n" } elsif (/^-newreq$/) { # create a certificate request system ("$REQ -new -keyout newkey.pem -out newreq.pem $DAYS"); $RET=$?; print "Request is in newreq.pem, private key is in newkey.pem\n"; } elsif (/^-newreq-nodes$/) { # create a certificate request system ("$REQ -new -nodes -keyout newkey.pem -out newreq.pem $DAYS"); $RET=$?; print "Request is in newreq.pem, private key is in newkey.pem\n"; } elsif (/^-newca$/) { # if explicitly asked for or it doesn't exist then setup the # directory structure that Eric likes to manage things $NEW="1"; if ( "$NEW" || ! -f "${CATOP}/serial" ) { # create the directory hierarchy mkdir $CATOP, $DIRMODE; mkdir "${CATOP}/certs", $DIRMODE; mkdir "${CATOP}/crl", $DIRMODE ; mkdir "${CATOP}/newcerts", $DIRMODE; mkdir "${CATOP}/private", $DIRMODE; open OUT, ">${CATOP}/index.txt"; close OUT; open OUT, ">${CATOP}/crlnumber"; print OUT "01\n"; close OUT; } if ( ! -f "${CATOP}/private/$CAKEY" ) { print "CA certificate filename (or enter to create)\n"; $FILE = <STDIN>; chop $FILE; # ask user for existing CA certificate if ($FILE) { cp_pem($FILE,"${CATOP}/private/$CAKEY", "PRIVATE"); cp_pem($FILE,"${CATOP}/$CACERT", "CERTIFICATE"); $RET=$?; } else { print "Making CA certificate ...\n"; system ("$REQ -new -keyout " .
