1. A method of enabling the provisioning of keys between a first user and a second user, the first user having a first computer, a first key and a first bootstrap key, and the second user having a second computer and a second key, the method comprising the steps of:
the first computer encrypting the first key with the first bootstrap key; the first user providing the encrypted first key to the second user via a first data store; the first user providing to the second user the first bootstrap key and in a manner independent of the first data store; the second computer decrypting the encrypted first key with the first bootstrap key for use by the second user; the second computer encrypting the second key with the first key; the second user providing the encrypted second key to the first user via a second data store; and the first computer decrypting the encrypted second key with the first key for use by the first user.
