for the paranoid...
Authored by: nemesis on Sep 09, '02 04:05:19AM

The blowfish algorithm used is 448bit..I stick with PGP Desktop Security 7 in classic and use its far higher encryption setting of 4096 bit ..this is higher than military strength. Lets face it if they say something is military strength then the military must have better encryption than that. I'm still waiting for a good gui to Gnu pgp... .I also think there may be issues with secure Disk Images and temporary finder database files -could be a security issue to think about with that option..

Comparing ciphers (was: for the paranoid...)

4096 bit PGP isn't necessarily better (or worse) than 448 bit Blowfish. The 4096 bits of key in PGP are for the asymmetric algorithm (== public key) used and you would expect a key length of about 4000 for reasonable security. Symmetric algorithms like Blowfish ought to provide 128 bits of effective key to be safe from an exhaustive key search. With some modern algorithms that means use a real key length of 256 bits, so Blowfish with 448 bits of key is playing fairly safe.
