1. A method for generating a key directory in a network comprising a plurality of nodes, comprising: (4) (1)

in an information processing apparatus comprising at least one computer processor for a first node in a computer network comprising a plurality of nodes: advertising a public key for a first node to the other nodes;

receiving public key information from each of the plurality of nodes; and

generating a public key directory that associates each node in the computer network with its public key.

2. The method of claim 1, further comprising: (3) (2)

retrieving a second public key directory from a second node of the plurality of nodes; and

updating the public key directory based on the second public key directory.

3. The method of claim 2, wherein the second public key directory is received periodically. (0)

4. The method of claim 2, wherein the second public key directory is received when the first node is restarted. (0)

5. The method of claim 2, wherein the second public key directory is received when a new node is discovered on the computer network. (0)

6. The method of claim 1, wherein the public key directory is stored to persistent media. (0)

7. The method of claim 1, wherein the public key is advertised using an API. (0)

8. The method of claim 1, further comprising: (0) (1)

9. A system for generating a key directory in a network comprising a plurality of nodes, comprising: (4) (2)

a computer network comprising a plurality of nodes, each node associated with a public key and a private key;

wherein: a computer processor for a first node of the plurality of nodes advertises a first node public key to the other nodes;

the computer processor for the first node receives public key information from each of the plurality of nodes; and

the computer processor for the first node generates a public key directory that associates each node in the computer network with its public key.

10. The system of claim 9, wherein: (3) (2)

the computer processor for the first node retrieves a second public key directory from a second node of the plurality of nodes; and

the computer processor for the first node updates the public key directory based on the second public key directory.

11. The system of claim 10, wherein the second public key directory is received periodically. (0)

12. The system of claim 10, wherein the second public key directory is received when the first node is restarted. (0)

13. The system of claim 10, wherein the second public key directory is received when a new node is discovered on the computer network. (0)

14. The system of claim 9, wherein the public key directory is stored to persistent media. (0)

15. The system of claim 9, wherein the public key is advertised using an API. (0)

16. The system of claim 9, wherein the computer processor for the first node sends a message to a second node in the computer network using a public key for the second node. (0)
