Functions ¶
func NewRecipientID ¶
NewRecipientID generates the recipient ID for a single-use sender. The ID is generated from the hash of the unencrypted request payload. The unencryptedPayload must contain a nonce to prevent collision on the same message being sent multiple times.
func NewRequestFingerprint ¶
func NewRequestFingerprint(pubKey *cyclic.Int) format.Fingerprint
NewRequestFingerprint generates the fingerprint used for the request message.
func NewRequestKey ¶
NewRequestKey generates the key used for the request message.
func NewRequestPartFingerprint ¶
func NewRequestPartFingerprint(dhKey *cyclic.Int, keyNum uint64) format.Fingerprint
NewRequestPartFingerprint generates the fingerprint for the request message for the given key number.
func NewRequestPartKey ¶
NewRequestPartKey generates the key for the request message that corresponds with the given key number.
func NewResponseFingerprint ¶
func NewResponseFingerprint(dhKey *cyclic.Int, keyNum uint64) format.Fingerprint
NewResponseFingerprint generates the fingerprint for the response message for the given key number.
func NewResponseKey ¶
NewResponseKey generates the key for the response message that corresponds with the given key number.
Types ¶
type TagFP ¶
TagFP uniquely identifies the module that the request message belongs to.
func NewTagFP ¶
NewTagFP generates a new tag fingerprint with the given tag. The tag can be anything, but should be long enough so that it is unique.
func UnmarshalTagFP ¶
UnmarshalTagFP generates a new TagFP from the specified bytes.
