- If FEE is legal to use in the US, then why did it mysteriously
- disappear from 3.0? Is NeXT afraid of a legal challange from RSA?
- I've been very curious about this since the early 3.0 announcements
- made a really big deal about this capability.
-
- Also, while you may trust ForYourEyesOnly to not have any trap doors
- in it, I don't. Will NeXT tell you how it works? Will you believe
- them? For example, the "Secure" application that's on the Educational
- Software Sampler CDROM looks rather cool. Its description claims:
-
- Description:
-
- Secure provides private single key encryption to user files.
- It can be used either as a standalone or Services menu
- application.
-
- It in fact does this. But if you are the paranoid type (and it pays
- to be if you're talking cryptography) and you "strings" your way
- through the application, you find that is uses the UNIX 'crypt'
- command! While crypt makes your file unreadable to the naked eye, it
- certainly has no real degree of security that I'd want to depend on;
- certainly not compared to DES, which is what I expected to find.
- Search "archie" for cbw, the Crypt-Breakers Workbench.
-
- While I certainly applaud NeXT for the really neat application
- interface, the business end of this app falls way short of what you'd
- want to depend on. I want to know what I'm getting and what I'm
- depending on. I really hope that a program like "Secure" becomes
- available which uses real cryptography.
-
- The principles behind RSA are pretty well known; the source code to
- PGP is also available. I would be a higher degree of trust in this
- software rather then a "black box" with unknown properties.
-
- If you don't believe that you can use PGP legally, perhaps you should
- wait for the RIPEM package to become avialable, which is distributed
- with the RSAREF software from RSA. I believe that you will be able to
- use this software for non-commercial purposes with RSA's blessing.
- RIPEM messages look somewhat like PEM, though it doesn't use
- certificates, just "bare" public/private keys.
