Assuming you meant two *giga*bytes, not two kilobytes, I think
the most common work-around is to pass the encrypted data on
gpg's standard input and read the decrypted data from its standard
output.  That is, instead of doing something like:

  gpg -d file.txt.enc

and expecting to get a file.txt after a successful decryption, do this:

  gpg -d < file.txt.enc > file.txt

Of course, the exact invocation depends on your programming language,
libraries and stuff (you may invoke a shell and pass it this command
with the redirections, or you may fork off a process and reopen its
file descripts 0 and 1, or...), but that's the general idea.

Hope that helps.

G'luck,
Peter

This sentence claims to be an Epimenides paradox, but it is lying.
