That makes sense. As Javascript is run on the client side on users' browsers, it MUST be publicly accessible and so this is the expected behaviour. On HTTP a .js file is just served in exactly the same way by the Web server as an HTML file or a PDF file. Javascript files are NEVER executed on the server so the file permissions are irrelevant. The file will be served correctly provided Apache can have read permission to the file.

What is the point of writing Javascript that cannot be accessed by clients?

What numeric CHMOD should be applied to these, which: Permit
the world and group to execute the commands contained in
the files, but Disallows display of the actual code contained
within the script to the world and group?
But hey, you can't run Javascript with the shell (if you know an interpreter that does, tell me)!! And as I said, unlike server-side languages such as Perl that can act as CGI programs, that will be executed by the Web server and just serve the generated output without divulging the sources, Javascript files are served verbatim as static resources and so either you let clients get it, or you don't. You can't have a Javascript that only executes but not readable, because the HTTP protocol is open. Even if browsers do not have a "view source" function, there are still so many ways to get the source. For instance, by a packet sniffer and everything must be there. You can't hide anything.

Javascript can only be obfuscated with difficult-to-read-variable-names and reducing the entire script into a one-liner with some unusual structure. This is already the utmost one can do to Javascript if he wants to make it hard for people wishing to hack or steal the sources, but still, that obfuscated code is available for access publicly, otherwise the browser will never be able to get the source to run it!

I am pretty sure your concepts has been screwed.

pyca(1) 						      General Commands Manual							   pyca(1)

NAME

       pyca - CA written in python

DESCRIPTION

       The  scripts  in  ths suite are basically wrappers around openssl(1). Additionally the scripts integrates the generic CA-functionality with
       the mail-system and apache for handling certificate requests; with LDAP for handling distributing certificates and  revocation  lists;  and
       cron for maintenance tasks.

PROGRAMMES

       ca2ldif.py
	      Write  CA  certificates  and CRLs to a LDIF file. This is intended for initially setting up the CA entries not for daily CRL update.
	      The entries are  of  objectclass	certificationAuthority	and  contain  the  attributes  cACertificate;binary,  authorityRevocation-
	      List;binary  and	certificateRevocationList;binary. This might require extending schemas on LDAPv2 servers. Have a look at your LDAP
	      servers configuration documentation.

       certs2ldap.py
	      Send all certs and CRLs to a LDAP repository.

       copy-cacerts.py
	      Copy all CA certificates defined in an OpenSSL configuration to a bundled PEM file or a directory with  hash-named  symbolic  links.
	      This is quite handy in conjunction with ApacheSSL or Apache with mod_ssl for copying the files for SSLCACertificateFile or SSLCACer-
	      tificatePath.

       ns-jsconfig.py
	      Create Javascript code containing all CA certificates defined in an OpenSSL configuration for use with the Netscape admin tool (cre-
	      ating netscape.cfg).

       print-cacerts.py
	      This simple script prints all CA certs on stdout. It is intended to generate authentic printouts (on paper!) of the CA certs finger-
	      prints and is typically run on the private CA system.  Choose the option --html to generate nicer formatted HTML-output  instead	of
	      the default textual output in ISO-8859-1.

       ns-jsconfig.py
	      Create a Javascript file to be included in a Netscape configuration file (netscape.cfg).
