Title: file encryption
Post by: unlovedwarrior on July 17, 2006, 12:03:54 PM
is there a way to encrypt and decrypt files without using some kind of software?

i googled file encryption without software and got the software.

or is even possible to encrypt without the software?

Be warned that many neophytes have encrypted their information from themselves permanently.

Well you could learn how to build a car, but aren't you just interested in driving?

encryption without software? that means you are looking at hardware? try google hardware encryption.

All encryption is done by software, so your question is not going to produce a meaningful answer.  Even in the case of "hardware" encryption, the encryption is performed by software running (possibly hard-coded) on that hardware.

If you are thinking of writing your own program to encrypt files, you just need to get to grips with the relevant encryption library for whichever programming language you're using.

Programming is not as hard as it sounds.  (At least the basic stuff.)

Here is a little snippet of javascript/HTML that will output the current date/time:
<p>The time/date is:
<###script language='javascript'>
    D = new Date();
    document.write(String(D));
</###script>
</p>
which produces (e.g.):
The date is: Tue Jul 18 2006 15:41:22 GMT+0000 (GMT)
The programming part just consists of two lines:
    D = new Date();
    document.write(String(D));
There you go - you can now write web pages with bits of code in them.  :)

NB The ### bits have to be removed to make this work.  They ned to be there for this post in order to bypass the CH script censor.
