how do we compare the existing data in the table with the entered one?
same way as anything else, for example:
select * from users where passwd=md5('my_password');
is there any other function which we can use here for both cases
encryption as well as for decryption at the script as well as database
level....
why do you need it encrypted?
Please do reply-all - you will get a quicker response (from me and the
list(s) might have suggestions I don't).

The crypt function can't be decrypted (whether it's in postgresql or
anywhere else).
Crypt is meant to be used for passwords and such that you don't need
to reverse (you only compare against).
