INTRODUCING S E C U R E D R I V E 1 . 1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ AVAILABLE NOW Secure Drive 1.0 users: Secure Drive 1.1 has three improvements over V1.0: * Two-drives bug fixed. Secure Drive 1.0 could get the drive letters out of order if you had two physical hard drives. V1.1 fixes this problem. * Enhanced passphrase security: Secure Drive 1.0 used a simple MD5 of the passphrase as the IDEA key. This allowed a fast passphrase search. V1.1 iterates the passphrase hash 2048 times to slow down an attacker. * One-step passphrase change. CRYPTDSK allows you to easily change your passphrase, without a separate encrypt/decrypt cycle. This also enhances security: there is no "window of opportunity" during which the data is in clear on the disk, and no magnetic traces of the plaintext. There is a Secure Drive version 1.2 going around. I was not aware of it until I saw an announcement on the Cypherpunks. This version contains some enhancements to interact with the PGPPASS variable, enabling you to easily use the same passphrase with PGP and Secure Drive. ***HOWEVER - it does not include either the bug fix or the security enhancements of version 1.1. While I would like to see these PGP-compatible features included in Secure Drive, the bugs need to be fixed. For now, please use V1.1. You will need to decrypt and re-encrypt your hard drive, because the new hashing algorithm generates a different IDEA key for the same passphrase. I will talk to the author of V1.2 about adding his improvements to V1.1 to create a version 1.3 soon. Secure Drive 1.1 is available within the U.S. and Canada ONLY, due to US export laws. FTP to csn.org, cd /mpj, and read README.MPJ. This is an export-controlled FTP site which also carries RIPEM and other cryptographic software. The file README.MPJ will explain how to access the cryptographic code from within the U.S. and Canada. You will be able to download immediately; there is no sign-up-and-wait procedure. (Ad continues) Do you have confidential or sensitive information on your DOS/Windows PC or laptop? Imagine what could happen if that data were to fall into the wrong hands through theft or unauthorized access. Protect your privacy with SecureDrive. SecureDrive allows you to create an encrypted hard drive partition and encrypted floppy disks. All of your sensitive data is automatically encrypted with the state-of-the-art IDEA cipher. You simply log in with your passphrase, and the program is completely transparent to your applications. The TSR uses only 2K RAM, and encrypts at the sector level. An intruder gets nothing - not even your directory listing. You can decrypt your disks at any time. The program automatically switches on and off as you access encrypted and unencrypted floppies. Invalid passwords will cause a Drive Not Ready error, locking out writes and protecting your data from damage. The program is Copylefted under the GNU General Public License, and source code in C and assembly language is included. This program is free and always will be. This program may be freely distributed within the U.S. and Canada; do not export it. Cypherpunks Write Code!
