it's the 2nd one. i need to retrieve it later. i really didn't want to get a prompt from the user, since it'd be better to prompt the password and lose the encryption. what do you think of getting the key from something in the system, like the current dir or the output of uname -s. would it still be secure? what i'm doing here is to store some irc nickname passwords in a file and when we login the perl script auto identifies the user.
any ideas for secure automation?

SYNOPSIS
pam_issue.so [noesc] [issue=issue-file-name]

machine's network node hostname (uname -n)
o
domain name of this system
release number of operating system (uname -r)
current time
s
operating system name (uname -s)
u
number of users currently logged in
U
same as u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users")
v
operating system version and build date (uname -v)
OPTIONS
noesc
Turns off escape code parsing.
issue=issue-file-name
The file to output if not using the default.
MODULE TYPES PROVIDED
Only the auth module type is provided.
RETURN VALUES
PAM_BUF_ERR
Memory buffer error.
PAM_IGNORE
The prompt was already changed.
PAM_SERVICE_ERR
