24.5. Create the /usr/bin/sign.sh program file
The openssl ca commands has some strange requirements and the default OpenSSL config doesn't allow one easily to use openssl ca directly. Therefore, well create this sign.sh program to replace it. Create the sign.sh program file, touch /usr/bin/sign.sh and add to this file:
#!/bin/sh
##
## sign.sh -- Sign a SSL Certificate Request (CSR)
## Copyright (c) 1998-1999 Ralf S. Engelschall, All Rights Reserved.
##
# argument line handling
CSR=$1
if [ $# -ne 1 ]; then
echo "Usage: sign.sign <whatever>.csr"; exit 1
fi
if [ ! -f $CSR ]; then
echo "CSR not found: $CSR"; exit 1
fi
case $CSR in
*.csr ) CERT="`echo $CSR | sed -e 's/\.csr/.crt/'`" ;;
* ) CERT="$CSR.crt" ;;
esac
# make sure environment exists
if [ ! -d ca.db.certs ]; then
mkdir ca.db.certs
fi
if [ ! -f ca.db.serial ]; then
echo '01' >ca.db.serial
fi
if [ ! -f ca.db.index ]; then
cp /dev/null ca.db.index
fi
# create an own SSLeay config
cat >ca.config <<EOT
[ ca ]
default_ca = CA_own
[ CA_own ]

certs = /etc/ssl/certs
new_certs_dir = /etc/ssl/ca.db.certs

RANDFILE = /etc/ssl/ca.db.rand
certificate = /etc/ssl/certs/ca.crt
private_key = /etc/ssl/private/ca.key
default_days = 365
default_crl_days = 30
default_md = md5

# sign the certificate
echo "CA signing: $CSR -> $CERT:"
openssl ca -config ca.config -out $CERT -infiles $CSR
echo "CA verifying: $CERT <-> CA cert"
openssl verify -CAfile /etc/ssl/certs/ca.crt $CERT
# cleanup after SSLeay
rm -f ca.config
rm -f ca.db.serial.old

exit 0

Now, make this program executable, and change its default permissions:
[root@deep] /# chmod 755 /usr/bin/sign.sh
|
: You can also find this program sign.sh in the mod_ssl distribution under the mod_ssl-version/pkg.contrib/ subdirectory, or on our floppy.tgz archive file. Also note that the section [ CA_own ] must be changed to refect your own environment and don't forget to change the openssl verify -CAfile /etc/ssl/certs/ca.crt $CERT line too.
