asyd-ca.pl

This is a little perl script to manage a Certification Authority using the openssl command. Though, like CA.[sh|pl] (from OpenSSL) it is very simple to use, and it ask only few questions. It comes with few templates files. One of these can be use to create wildcard certificates.

Any suggestion, bug report, feature request (include template) are welcome.

• Few requirements : Perl and Openssl
• Very easy to use, no OpenSSL knowledges required, but theirs are welcome
• asyd-ca.pl doesn't require Openssl templates
• Extend it via Openssl's templates files (require good OpenSSL knowledges)

# ls -1
asyd-ca.pl
changes.log
templates
# vi templates/ca-req.cnf
[..]
emailAddress     = asyd@asyd.net
countryName      = FR
organizationName = asyd.net
commonName       = "asyd dot net CA"
localityName     = Paris

It's more or less the only file you need to edit. It's very easy, isn't it ?

# ./asyd-ca.pl init
[openssl's output remove]
# ls -1
asyd-ca.pl
CA
certs
changes.log
keys
misc
pkcs12
reqs
templates

The content of each directory is explain below.

Note: You can edit the file templates/simple.cnf, especially the field with _default suffix. These values are the default one (but can be override) used by openssl while prompting for the certificat request informations.

# ./asyd-ca.pl req jboss
[skip openssl useless output]
Organization Name (required) [asyd.net]:
Country Name (2 letter code, required) [FR]:
Email Address (optional) [asyd@asyd.net]:
Common Name (MUST match the DNS name) [www.asyd.net]:jboss.asyd.net
Organizational Unit Name (optional) []:

As you can see, I use default value set in templates/simple.cnf, except for the common name, where I override the value with jboss.asyd.net. As you probably know, the field CN (CommonName) of a service certificate (e.g. https) MUST match the DNS name used to reach the service.

# ./asyd-ca.pl sign jboss
[skip openssl useless output]
Sign the certificate? [y/n]:y
1 out of 1 certificate requests certified, commit? [y/n]y

I'm now able to use the certificate, using file certs/jboss.pem. Though, in the special case of Jboss, I need a pkcs12 file, so I just do :

# ./asyd-ca.pl pkcs12 jboss
Enter export password: 
Verifying - Enter export password:
# ls -l pkcs12/jboss.p12
-rw-r----- 1 asyd asyd 2288 2006-01-09 20:50 pkcs12/jboss.p12

Since a PKCS12 file include a key, a password is recommanded.

• Export cert (including CRL) to LDAP
• Remove openssl output when useless
