Technically, yes you could, if the program the end user had could accept the RSA key
that cardcrypt/textcrypt created and you gave them.
Problem is, we haven't actually managed to do this yet - the PGP client on Windows has
the option of importing a legacy RSA key but that key needs to be
PGP talks about Radix64 format, and I always thought
this was the same as Base64. So, I would have thought
it was basically a matter of constructing the
appropriate wrapper (RFC 1991) around the key.
But then, I could be completely wrong :)

If I encrypt something with one of the PertWeb encyption tools
(http://developer.perthweb.com.au/), can another user (assuming the user has
the private key) decrypt the string with software other than a cfx tag? I

It would be much easier to do this with ssl certificates. You wouldn't
need commercial certs for this. With IIS, you can generate both a server
and client cert and enrcrypt traffic between them. I am pretty sure that
there is an open source system to do the same on Linux.

I used a similar technique in my custom tag cf_cryp that's in the
developer's gallery. I actually use the encrypt() function in CF and
then do various operations to convert characters, shift bits and flip
nibbles. I also added a checksum (also encoded) so I could validate
the

You may be able to obfuscate your information from most people but anyone with some
time and a decent system will
most likely have a easy go with your algorithm. What you are doing sounds like very
simple encryption scheme and
is rife for frequency analysis which would not be that hard

You might want to look at this http://jenghis.thirdtier.com/crypto/ which uses Strong
Crypto. This URL is rather
outdated and the lattest version I have written supports all the AES systems as well
as various forms of public key
crypto and exchange.
Its also super fast so its fine for little

pardon my ignorance, but isn't the encryption method for ALL publicly
available encryption techniques known?
The style maybe known, but the one used for CFEncrypt isn't particularly
difficult to decrypt - thus if someone can get to your site and knows your
using CF, then they'll try the
Oook.
We'll take it a step further.
There are publicly available CF Tags to decrypt cf encoded pages.
There is C++ Source to decode CF Encrypted pages.
There is Perl scripting to decode CF Encrypted pages.
My little pommeranian can decode cf encrypted pages with a doggie decoder ring and a

Structure your ColdFusion code with Fusebox. Get the official book at
decrypting. A BAD encryption
scheme will fall apart. CFENCRYPT is the latter. DON'T ever use it for
encrypting sensitive material (e.g. CC numbers).
