Encrypted File System on SCO?

Does anyone know of an encrypted file system for SCO's OpenDesk 5?
For example, Linux has CFS, and I think DOS has SFS.

I don't know of a Filesystem as such...  But there is a good product
out there that does **awesome** (I'm just a satisfied customer) encryption.

The company is called TECSEC.  They have a product that runs on SCO and
a port that runs on the Windoze platforms.  It allows you to encrypt
directory structures, files, etc...  I suppose you could create a seperate
filesystem (say HTFS...) and then run the VEIL product on that entire
Filesystem.  Their product has been patented and is a good product.  They
also provide Encryption services that run across Cellular networks, and
a satellite terminal service.

Again...I'm just a satisfied (VERY) customer...

I ported CFS to OSR5 some time ago, just as an experiment, and it
seemed to work.  I don't have the port any longer, but I recall it was
pretty easy; one of the ported-to platforms was very close.

 
 
 

1. Encrypting again an already encrypted file increase security ?

Assume I have a file which is already encrypted with lets say a Blowfish tool.
If I encrypt exactly this file again with another encryption algorithm tool
(e.g. IDEA or DES or RSA or whatever) does this improve the secureness ?
Or is the crackability (read: the theoretical probability of being cracking
within a certain period of time) equal the security/safety of the best of the
two used encryption methods ? That would mean that applying a less secure
encryption methdo would NOT improve the security.
