Message-ID: <200403310824.39207.lionel.ferette@belnet.be> From: lionel.ferette at belnet.be (Lionel Ferette) Subject: SMTP Encryption (S/MIME) for Outlook question -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In the wise words of Crist J. Clark, on Wednesday 31 March 2004 03:39: [SNIP pertinent comments] Not much to add to the S/MIME part: while email clients are generally rather user-friendly, the casual user will get lost as soon as you mention "X.509", "public key" or "private key". And managing CRL's is no piece of cake either. > To encypt the individual messages? You need, or maybe the people > laying this on you, need to think about this a bit more.

Often you'll need one more thing: the ability for management to recover the plaintext of an encrypted message. Key escrow, in a word. I don't want to start an argument about whether it's a good idea or not, but face it, it's a requirement in most medium to large companies. [SNIP other pertinent comments] Cheers, Lionel - -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin Lionel Ferette BELNET CERT Coordinator Rue de la Science 4 Tel: +32 2 7903333 1000 Brussels Fax: +32 2 7903335 Belgium PGP Key Id: 0x5662FD4B -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQFAamQmDd3gqVZi/UsRAgOmAKDbH+vBP8JhUVA+BN/X2LC1uVvNRACeISlC B6DkOKOkEZDssrasazRP84A= =2SG0 -----END PGP SIGNATURE-----
