getPubKey (26)

The getPubKey message is used to request the public key of a specific user. It is primarily used by a client when adding a contact or when interacting with a bot to get the public key of another user within a group chat, which is necessary to verify their message signatures.

Core Data Types

• IxiBytes: See IxiBytes Encoding.

Payload Structure

Field	Data Type	Min	Max	Description
targetAddress	IxiBytes	*	*	The address of the user whose public key is being requested.

Behavioral Notes

• Standard Request: A user's client sends a getPubKey message with an empty payload to a contact to ask for their public key.
• Bot Request: A bot may receive a request from a user to identify another user in a chat. The bot would then send a getPubKey message to the target user, including their address in the targetAddress field.
• Response: Upon receiving a getPubKey message, a node MUST respond with a pubKey message containing the public key.
