NewRotateKey makes a new rotate key given sig3 skeletons (Outer and Inner) and also the PTKs that are going to be advertised in the sig3 link.

The values are picked so they don't conflict with Sigchain V1 and V2 SeqType's.

The values are picked so they don't conflict with Sigchain V1 and V2 SeqType's.

These values are picked so they don't conflict with Sigchain V1 and V2 link types.

Base struct for sig3 links that contains much of the raw material pulled down or off local storage.

If the inner link is encrypted, we specify the encryption parameters with this offloaded structure.

Sig3ExportJSON is for communicating with the API server.

OuterLink V3 is the third version of Keybase sigchain signatures, it roughly approximates the outer link v2s that we have previously used.

RotateKey is a sig3 link type for a PTK rotation.

Sig3Bundle is for storing sig3 links locally.

Generic sig3 wrapper class, should implement the following interface.
