Distribution
This program is shareware, although some versions may be demoware if they are distributed in areas in which export control is not possible.  The wonderful government of the United States in which the author lives has chosen to declare the algorithms used in this product (specifically IDEA) as “munitions” which are illegal to export.  In other words, anyone caught exporting or transmitting the full version of this program from the US (or Canada) could theoretically be convicted of international arms trafficking.  I know it sounds totally absurd, but it is true.  It is especially absurd given that the IDEA algorithm was invented in Switzerland.  This law is why you don’t see a lot of shareware or freeware strong encryption programs that are freely distributed.

The version of this program which is demoware and is freely distributable to the world has no encryption (called 1.1D).  The security of the demoware version is non-existent from a cryptographic point of view.  All it effectively does is place password protection on mounting the CryptDisk file.  It will not mount real CryptDisks.  Do not use the demo version of the application for anything sensitive.

The full version of this program is available directly from the author after proof of US citizenship.  It is also available at selected anonymous FTP sites in the US which restrict access to legal US and Canadian users.  Information on obtaining the full version can be found in:

ftp://ftp.primenet.com/users/w/wprice/README

or (the following site will be eliminated soon)

ftp://ftp.netcom.com/pub/wp/wprice/README

Only US and Canadian postal and email addresses may obtain this version.  To register the full version (or to obtain a copy if you can’t get it elsewhere), send $20 US (add $5 if you need shipping) to the address below.  Make checks payable to Will Price.

If you have an internet or AOL email address which is capable of receiving files, you will be emailed the full version on receipt.  Otherwise, please include $5 to have it shipped to your US or Canadian postal address on disk.  Please include your name, address, email address, whether your email address can receive file attachments, and any other comments you might have.  If you have questions about this procedure, please send email to wprice@primenet.com.

The full version is also PowerPC native to the extent possible providing incredible speed increases on those computers.  A PowerPC encrypts 19 times faster native than it does running emulated code.

The source code is also available for an extra $20.  So, if you would like registration, source and shipping, please include $45.  Because of the size increase, the application itself in both demo and full releases is not PowerPC native.  It doesn't affect the speed of the disk and would increase the archive size by about 200K.  The source release contains a PowerPC application project which a user can compile to get a native app.  Note that the PowerPC native portion of CryptDisk which matters in terms of disk access times is the driver, not the application.  The driver contains native encrypt/decrypt code in the full release.
