I think perl would be good for this, it certainly should be easy. Tie::File is good for working with large files since it does not read them into memory, but it does alter the original file so you have to make sure to open the file in readonly mode. A preliminary script:
I am not sure how efficient/ineffiecient this is though.

GnuPG::Tie(3pm) User Contributed Perl Documentation GnuPG::Tie(3pm)NAME
GnuPG::Tie::Encrypt - Tied filehandle interface to encryption with the GNU Privacy Guard.
GnuPG::Tie::Decrypt - Tied filehandle interface to decryption with the GNU Privacy Guard.
SYNOPSIS
use GnuPG::Tie::Encrypt;
use GnuPG::Tie::Decrypt;
tie *CIPHER, 'GnuPG::Tie::Encrypt', armor => 1, recipient => 'User';
print CIPHER <<EOF;
This is a secret
EOF

close CIPHER;
untie *CIPHER;
tie *PLAINTEXT, 'GnuPG::Tie::Decrypt', passphrase => 'secret';

DESCRIPTION
GnuPG::Tie::Encrypt and GnuPG::Tie::Decrypt provides a tied file handle interface to encryption/decryption facilities of the GNU Privacy
guard.
With GnuPG::Tie::Encrypt everyting you write to the file handle will be encrypted. You can read the ciphertext from the same file handle.
With GnuPG::Tie::Decrypt you may read the plaintext equivalent of a ciphertext. This is one can have been written to file handle.
All options given to the tie constructor will be passed on to the underlying GnuPG object. You can use a mix of options to output directly
to a file or to read directly from a file, only remember than once you start reading from the file handle you can't write to it anymore.
