WebDiffie–Hellman key exchange. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher. WebCharter for Working Group. OpenPGP is an Internet standard that covers object encryption, object. signing, and identity certification. These were defined by the first. incarnation of the OpenPGP working group. The following is an excerpt from the charter of the original incarnation. of the openpgp working group.
