read/write files in an encrypted partition

I am attempting to create, edit and read files in an encrypted partition in Suse 8.2. During boot, I am prompted to enter a passphrase, presumably a key. Using chmod 775 I believe I have made the mount point (/media/secure) writable by me (a member of "users"), as well as root. A google search mainly discusses VPNs, network access, etc. I get an error that I might not have permission when I try to write a file. -- John Sowden American Sentry Systems.
