Subject Re: [users@httpd] Client Certificates - HOWTO?
Date Sun, 22 Aug 2004 05:30:43 GMT
Hi Alan
concerning the passphrase, my findings where like this:

using openssl on linux:

you create a server request and key with
openssl req -new -keyout $DIR/server-key.pem -out \
$DIR/server-req.pem -days 3600 -config $DIR/openssl.cnf

at this point you MUST specify a passphrase. i have not found out the 
option for openssl, which allows you to not specify a passphrase.

you can then remove the passphrase from the key:
openssl rsa -in $DIR/server-key.pem -out $DIR/server-key.pem

whether you can use the certificate which you create with such a key may 
depend on the browser, where you want to install it.
