- NeXT could not export 3.0 if it included FEE. In this case it was
- "all or nothing." There was no point in trying to deal with all the
- hassles of exportable and non-exportable versions just for FEE.

- FYEO uses either FEE or EE. EE is a well documented algorithm and it
- is recognized as secure. While the mathematical speedups in FEE may
- weaken the algoritm, it comes down to "how secure must this really
- be." Crypt is not secure. I would say that DES is not secure as well
- if you want to talk about theoretical absolutes. I would say that DES
- is "secure enough" unless you need to keep things secure from
- governments with the resources to break it.
