Functions

func DecorateJWT

DecorateJWT returns a decorated JWT that describes the kind of JWT

func DecorateSeed 

func DecorateSeed(seed []byte) ([]byte, error)

DecorateSeed takes a seed and returns a string that wraps the seed in the form: 

************************* IMPORTANT *************************
NKEY Seed printed below can be used sign and prove identity.
NKEYs are sensitive and should be treated as secrets.

func IssueUserJWT 

func IssueUserJWT(scopedSigningKey nkeys.KeyPair, accountId string, publicUserKey string, name string, expirationDuration time.Duration, tags ...string) (string, error)

IssueUserJWT takes an account scoped signing key, account id, and use public key (and optionally a user's name, an expiration duration and tags) and returns a valid signed JWT. The scopedSigningKey, is a mandatory account scoped signing nkey pair to sign the generated jwt (note that it _must_ be a signing key attached to the account (and a _scoped_ signing key), not the account's private (seed) key). The accountId, is a mandatory public account nkey. Will return error when not set or not account nkey. The publicUserKey, is a mandatory public user nkey. Will return error when not set or not user nkey. The name, is an optional human-readable name. When absent, default to publicUserKey. The expirationDuration, is an optional but recommended duration, when the generated jwt needs to expire. If not set, JWT will not expire. The tags, is an optional list of tags to be included in the JWT.

Returns: string, resulting jwt. error, when issues arose.
