#!/bin/sh # # 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 ... 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 # # default openssl.cnf file has setup as per the following # demoCA ... where everything is stored cp_pem() { infile=$1 outfile=$2 bound=$3 flag=0 exec <$infile; while read line; do if [ $flag -eq 1 ]; then echo $line|grep "^-----END.*$bound" 2>/dev/null 1>/dev/null if [ $? -eq 0 ] ; then echo $line >>$outfile break else echo $line >>$outfile fi fi echo $line|grep "^-----BEGIN.*$bound" 2>/dev/null 1>/dev/null if [ $? -eq 0 ]; then echo $line >$outfile flag=1 fi done } usage() { echo "usage: $0 -newcert|-newreq|-newreq-nodes|-newca|-sign|-verify" >&2 } if [ -z "$OPENSSL" ]; then OPENSSL=openssl; fi if [ -z "$DAYS" ] ; then DAYS="-days 365" ; fi # 1 year CADAYS="-days 1095" # 3 years REQ="$OPENSSL req $SSLEAY_CONFIG" CA="$OPENSSL ca $SSLEAY_CONFIG" VERIFY="$OPENSSL verify" X509="$OPENSSL x509" PKCS12="openssl pkcs12" if [ -z "$CATOP" ] ; then CATOP=./demoCA ; fi CAKEY=./cakey.pem CAREQ=./careq.pem CACERT=./cacert.pem RET=0 while [ "$1" != "" ] ; do case $1 in -\?|-h|-help) usage exit 0 ;; -newcert) # create a certificate $REQ -new -x509 -keyout newkey.pem -out newcert.pem $DAYS RET=$? echo "Certificate is in newcert.pem, private key is in newkey.pem" ;; -newreq) # create a certificate request $REQ -new -keyout newkey.pem -out newreq.pem $DAYS RET=$? echo "Request is in newreq.pem, private key is in newkey.pem" ;; -newreq-nodes) # create a certificate request $REQ -new -nodes -keyout newreq.pem -out newreq.pem $DAYS RET=$? echo "Request (and private key) is in newreq.pem" ;; -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" -o ! -f ${CATOP}/serial ]; then # create the directory hierarchy mkdir -p ${CATOP} mkdir -p ${CATOP}/certs mkdir -p ${CATOP}/crl mkdir -p ${CATOP}/newcerts mkdir -p ${CATOP}/private touch ${CATOP}/index.txt fi if [ ! -f ${CATOP}/private/$CAKEY ]; then echo "CA certificate filename (or enter to create)" read FILE # ask user for existing CA certificate if [ "$FILE" ]; then cp_pem $FILE ${CATOP}/private/$CAKEY PRIVATE cp_pem $FILE ${CATOP}/$CACERT CERTIFICATE RET=$? if [ ! -f "${CATOP}/serial" ]; then $X509 -in ${CATOP}/$CACERT -noout -next_serial \ -out ${CATOP}/serial fi else echo "Making CA certificate ..." $REQ -new -keyout ${CATOP}/private/$CAKEY \ -out ${CATOP}/$CAREQ $CA -create_serial -out ${CATOP}/$CACERT $CADAYS -batch \ -keyfile ${CATOP}/private/$CAKEY -selfsign \ -extensions v3_ca \ -infiles ${CATOP}/$CAREQ RET=$? fi fi ;; -xsign) $CA -policy policy_anything -infiles newreq.pem RET=$? ;; -pkcs12) if [ -z "$2" ] ; then CNAME="My Certificate" else CNAME="$2" fi $PKCS12 -in newcert.pem -inkey newreq.pem -certfile ${CATOP}/$CACERT \ -out newcert.p12 -export -name "$CNAME" RET=$? exit $RET ;; -sign|-signreq) $CA -policy policy_anything -out newcert.pem -infiles newreq.pem RET=$? cat newcert.pem echo "Signed certificate is in newcert.pem" ;; -signCA) $CA -policy policy_anything -out newcert.pem -extensions v3_ca -infiles newreq.pem RET=$? echo "Signed CA certificate is in newcert.pem" ;; -signcert) echo "Cert passphrase will be requested twice - bug?" $X509 -x509toreq -in newreq.pem -signkey newreq.pem -out tmp.pem $CA -policy policy_anything -out newcert.pem -infiles tmp.pem RET=$? cat newcert.pem echo "Signed certificate is in newcert.pem" ;; -verify) shift if [ -z "$1" ]; then $VERIFY -CAfile $CATOP/$CACERT newcert.pem RET=$? else for j do $VERIFY -CAfile $CATOP/$CACERT $j if [ $? != 0 ]; then RET=$? fi done fi exit $RET ;; *) echo "Unknown arg $i" >&2 usage exit 1 ;; esac shift done exit $RET
