Most standards that include encryption are to do with transport-level
encryption (SSL, SSH, IPSec/IKE, WPA etc). However, OpenPGP, XML
encryption, and CMS all offer a mode of operation more like this:
- Bob sends Alice a packet that includes a public key for encryption
- Offline, Alice can take this packet and a message and generate an
encrypted message
- The message reaches Bob by whatever means
- Bob decrypts it
Are there other standards of this shape that I've left out here? Thanks!
