-This is a go library to help the next generation of web and decentralized applications make use
-of UCANs in their authorization flows.
-
-User Controlled Authorization Networks (UCANs) are a way of doing authorization where users are fully in control. OAuth is designed for a centralized world, UCAN is the distributed user controlled version.
-
-## Resources
-
-### Specifications
-
-The UCAN specification is separated in multiple sub-spec:
-- [Main specification](https://github.com/ucan-wg/spec)
-- [Delegation](https://github.com/ucan-wg/delegation/tree/v1_ipld)
-- [Invocation](https://github.com/ucan-wg/invocation)
-- [Container](https://github.com/ucan-wg/container)
-
-Not implemented yet:
-- [Revocation](https://github.com/ucan-wg/revocation/tree/first-draft)
-- [Promise](https://github.com/ucan-wg/promise/tree/v1-rc1)
-
-### Talks
-
-- [Decentralizing Auth, and UCAN Too - Brooklyn Zelenka (2023)](https://www.youtube.com/watch?v=MuHfrqw9gQA)
-- [What's New in UCAN 1.0 - Brooklyn Zelenka (2024)](https://www.youtube.com/watch?v=-uohQzZcwF4)
-
-## Status
-
-`go-ucan` currently support the required parts of the UCAN specification: the main specification, delegation and invocation. It leverages the sibling project [`go-did-it`](https://code.sonr.org/go/did-it) for easy and extensible DID support.
-
-Besides that, `go-ucan` also includes:
-- support for encrypted values in token's metadata
-
-## Getting Help
-
-For usage questions, usecases, or issues reach out to us in our `go-ucan`
-[Discord channel](https://discord.gg/3EHEQ6M8BC).
-
-We would be happy to try to answer your question or try opening a new issue on
-Github.

+### Testing
+
+The test suite for this package includes test vectors provided by the
+authors of the [`did:key` method specification](https://w3c-ccg.github.io/did-method-key/).
+Some of these tests provide the public key associated with a `did:key`
+as JWKs and an extra (test-only) dependency has been added to unmarshal
+the JWK into a Go `struct`.  Support for the `secp256k1` encryption
+algorithm is experimental (but stable in my experience) and requires the
+addition of the following build tag to properly run:
+
+```
+// go:build jwx_es256k
+```
+
+WARNING: These tests will not run by default!
+
+To include these tests from the CLI, execute the following command:
+
+```
+go test -v ./did -tags jwx_es256k
+```
+
+It should also be possible to configure your IDE to run these tests.  For
+instance, in Codium, add the following JSON snippet to your local project
+configuration:
+
+```
+"go.testTags": "jwx_es256k",
+```

-// Package delegationtest provides a set of pre-built delegation tokens
-// for a variety of test cases.
-//
-// For all delegation tokens, the name of the delegation token is the
-// Issuer appended with the Audience.  The tokens are generated so that
-// an invocation can be created for any didtest.Persona.
-//
-// Delegation proof-chain names contain each didtest.Persona name in
-// order starting with the root delegation (which will always be generated
-// by Alice). This is the opposite of the list of cic.Cids that represent the
-// proof chain.
-//
-// For both the generated delegation tokens granted to Carol's Persona and
-// the proof chains containing Carol's delegations to Dan, if there is no
-// suffix, the proof chain will be deemed valid.  If there is a suffix, it
-// will consist of either the word "Valid" or "Invalid" and the name of the
-// field that has been altered. Only optional fields will generate proof
-// chains with Valid suffixes.
-//
-// If changes are made to the list of Personas included in the chain, or
-// in the variants that are specified, the generated Go file and delegation
-// tokens stored in the data/ directory should be regenerated by running
-// the following command in this directory:
-//
-//	cd generator && go run .
-//
-// Generated delegation Tokens are stored in the data/ directory and loaded
-// into the delegation.Loader.
-// Generated references to these tokens and the tokens themselves are
-// created in the token_gen.go file. See /token/invocation/invocation_test.go
-// for an example of how these delegation tokens and proof-chains can
-// be used during testing.
