Let me analyze your steps to see what you'd like to achieve in each of them. 0. Alice and Bob knows each other's email addresses: alice@A and bob@B. 1. Bob sends Alice his public key at Alice email address alice@A. 2. Alice relies to Bob with her public key. 3. Alice calls B's support and asks

Hi Martinho, After I thought about it more, I have kind of drawn the conclusion that even for signing, only using a SmartCard cannot achieve authenticity. With a write-only SmartCard which computes signature on the card, it's true that it can protect the signing key. However, if it's used in a

If the host machine is compromised, what's the purpose of doing encryption on the SmartCard? Attackers don't need to know the key to get your plaint ext, because it is on the host machine. I guess that what you meant was signing, using a SmartCard to sign has the benefits you mentioned, but not

Fwd: tar, compress, split and then encrypt a list of files

Dear mailing list, right now I have a working workstream that gets paths from a text file and: tar -> compress -> encrypt -> split (over each line/entry) Probably there is a security issue here as some of the paths are dozens of gigabytes in size. I would like to swap the 'encrypt -> split'

There's an important distinction to be made between using this approach and using a SmartCard. The encrypted USB drive approach leaks the keys into the machine you're using it from; they're accessible by simply reading the filesystem (thus the claim that "When you unplug the USB, your keys are
