copy files without password in script

1. I wrote a ftp code to copy a file from unix box to another unix box. But it has clear text password in the code. Due to security constraints, clear text password in the code is not allowed. Please let me know the ways to write the code without prompting for password.

2. I tried writing scp command using public/private key pairs. Donno wat mistake i found in this procedure, it is not working. I believe the mistake would be in the procedure. Something other than that like permissions, or server compatiblity or something else. Let me know these kind of constraints required for scp.

Please help me asap. I am breaking my head for two days for this Smilie

NAME
gshadow - shadowed group file DESCRIPTION
/etc/gshadow contains the shadowed information for group accounts. This file must not be readable by regular users if password security is to be maintained. Each line of this file contains the following colon-separated fields: group name It must be a valid group name, which exist on the system. encrypted password Refer to crypt(3) for details on how this string is interpreted. If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, users will not be able to use a unix password to access the group (but group members do not need the password). The password is used when a user who is not a member of the group wants to gain the permissions of this group (see newgrp(1)). This field may be empty, in which case only the group members can gain the group permissions. A password field which starts with an exclamation mark means that the password is locked. The remaining characters on the line represent the password field before the password was locked. This password supersedes any password specified in /etc/group. administrators It must be a comma-separated list of user names. Administrators can change the password or the members of the group. Administrators also have the same permissions as the members (see below). members It must be a comma-separated list of user names. Members can access the group without being prompted for a password. You should use the same list of users as in /etc/group. FILES
