Some a= re > not, some will be broken as soon as we get quantum-computers ;) Are we missing the obvious? The easiest think to 'break' is the weakest li= nk=20 in the chain. In such a *hypothetical* case that would be the person who i= s=20 in possession of the passphrase. I would expect that such a person would b= e=20 invariably labeled a "hacker" and condemned to eternity . . . Cracking the encryption algorithm by computation would only be necessary if= =20 the said person was not able to disclose the key due to absence, or due to = an=20 inability to recover from the vegetative (or worse) state that the=20 questioning methods may have inadvertently induced. :P =2D-=20 Regards, Mick --nextPart2992520.mt75h2EtZm Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQBHBUOO5Fp0QerLYPcRAjMXAKCdGn6uoHTPxf90CosHQs5dJ3JjogCeOSUq UPLRpfwW2u/weK5PHqw7mD8= =G9Pt -----END PGP SIGNATURE----- --nextPart2992520.mt75h2EtZm-- -- gentoo-user@gentoo.org mailing list
