Re: Removing blanks from a varning length field.

I think we are getting diverted from main topic what i meant was that even
i tried as you said on fly that flat file should be created with exact
length of that decrypted value even that i tried please see below code
but n1 variable which is holding the value of %len(outrec) in debug mode
tells it's value to be 64 that means still after doing those %trimr on
field or data structure as well have some extra junk value because length
of decrypted value is 48 only so 64-48 =16 these 16 length is full of
garbage which i don't want to write in my flat file .

sorry i did not understand what you mean but let me explain somethings
clearly:-

1) decrypted output of this AES128 algorithm is uncertain.

One step at a time... There are only two things that you can do
about this AES128 algorithm you mention. It must either accept a valid
varying-length parameter and handle it as such or there must be a separate
parameter which allows you to pass a length value in addition to the data
to be encrypted/decrypted. No one can answer those issues for you (unless
they are familiar with the process of which you are speaking). You must
be able to analyze the AES128 algorithm to determine which of the above
two requirements can be met.


Sincerely,

Dave Clark
