I have a Question maybe someone can explain to me.
Say company Acme has a PKI structure.
Company/User Beta also has PKI or is using PKI software
It allows S/MIME and Proprietary Keys to be imported into and AcmeUser's
keyrings/address books.
If User@Acme.com uses the key from AnotherUser@Acme.com I as the Key
Escrow CA can open/un-encrypt/read the mail using the Escrowed Private
keys.
But If User@Acme.com uses the Public Key from User@Beta.com to encrypt.
Can I open this message using only the Keys I have Escrowed?
Ie.. Only AcmeUser's Public/private pair?
Or is it encrypted with the Public key of UserBeta and I am SOL?
It's a discussion and I think I'm right but I'm having a hard time
trackling down facts online about this.
Which makes me think either it's so easy to open it that's it's just a
given.
or It's impossible and so blatant that it's a given.
or I'm an ass who skipped some whitepapers I should have read.
btw: I believe your SOL without that other key as it's encrypted with
it. Am I right?
