Terminology

Term Description
AccessKey Gives access to the ODIN network for a customer. It is a 44 character long Base64-String, which consists of a version, random bytes and a checksum.
SecretKey Generated from the AccessKey, it is based on the Ed25519-Curve and used to sign a Token generated by the customer.
PublicKey Generated from the AccessKey, it is based on the Ed25519-Curve and must be uploaded to 4Players so that a generated Token can be verified.
KeyId A shortened PublicKey, included in Token, making it possible to identify what PublicKey must be used to verify the Token.
Token A JWT given to the game clients that allows them to connect to a voice/video chat room in the ODIN network.
