Also, you could encrypt, or otherwise scramble the file. Depending on your Unix, you may have the "crypt" command installed, or something that could do what you want (PGP, GnuPG, BestCrypt, etc..). Warning: the learning curve gets steeper depending on what features you need / want, but in some cases, it's more than worth it.
I currently use GnuPG and BestCrypt. GnuPG is used for email and other small text snippets, while BestCrypt is used for secure file storage - It's a good idea, and farily straight forward: You create a data container of a given size, install the special device drivers, and mount it as a live filesystem. Just make sure you unmount it on your way out, otherwise it's not too useful, right?

gnupg::revoker
GnuPG::Revoker(3pm) User Contributed Perl Documentation GnuPG::Revoker(3pm)
NAME
GnuPG::Revoker - GnuPG Key Revoker Objects
SYNOPSIS
# assumes a GnuPG::PrimaryKey object in $key
my $revokerfpr = $key->revokers->[0]->fingerprint();
DESCRIPTION
GnuPG::Revoker objects are generally not instantiated on their own, but rather as part of GnuPG::Key objects. They represent a statement
that another key is designated to revoke certifications made by the key in question.
OBJECT METHODS
new( %initialization_args )
This methods creates a new object. The optional arguments are initialization of data members.
is_sensitive()
Returns 0 if the revoker information can be freely distributed. If this is non-zero, the information should be treated as "sensitive".
Please see http://tools.ietf.org/html/rfc4880#section-5.2.3.15 for more explanation.
compare( $other, $deep )
Returns non-zero only when this designated revoker is identical to the other GnuPG::Revoker. If $deep is present and non-zero, the
revokers' signatures will also be compared.
OBJECT DATA MEMBERS
fingerprint
A GnuPG::Fingerprint object indicating the fingerprint of the specified revoking key. (Note that this is *not* the fingerprint of the
key whose signatures can be revoked by this revoker).
algo_num
The numeric identifier of the algorithm of the revoker's key.
signatures
A list of GnuPG::Signature objects which cryptographically bind the designated revoker to the primary key. If the material was
instantiated using the *_with_sigs() functions from GnuPG::Interface, then a valid revoker designation should have a valid signature
associated with it from the relevant key doing the designation (not from the revoker's key).
Note that designated revoker certifications are themselves irrevocable, so there is no analogous list of revocations in a
GnuPG::Revoker object.
