Update transit public keys for Ed25519 support (#20727)
* Refine documentation for public_key

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>

* Support additional key types in importing version

This originally left off the custom support for Ed25519 and RSA-PSS
formatted keys that we've added manually.

* Add support for Ed25519 keys

Here, we prevent importing public-key only keys with derived Ed25519
keys. Notably, we still allow import of derived Ed25519 keys via private
key method, though this is a touch weird: this private key must have
been packaged in an Ed25519 format (and parseable through Go as such),
even though it is (strictly) an HKDF key and isn't ever used for Ed25519.

Outside of this, importing non-derived Ed25519 keys works as expected.

* Add public-key only export method to Transit

This allows the existing endpoints to retain private-key only, including
empty strings for versions which lack private keys. On the public-key
endpoint, all versions will have key material returned.

Provide public key encryption via transit engine (#17934)
* import rsa and ecdsa public keys

* allow import_version to update public keys - wip

* allow import_version to update public keys

* move check key fields into func

* put private/public keys in same switch cases

* fix method in UpdateKeyVersion

* move asymmetrics keys switch to its own method - WIP

* test import public and update it with private counterpart

* test import public keys

* use public_key to encrypt if RSAKey is not present and failed to decrypt
if key version does not have a private key

* move key to KeyEntry parsing from Policy to KeyEntry method

* move extracting of key from input fields into helper function

* change back policy Import signature to keep backwards compatibility and
add new method to import private or public keys

* test import with imported public rsa and ecdsa keys

* descriptions and error messages

* error messages, remove comments and unused code

* changelog

* documentation - wip

* suggested changes - error messages/typos and unwrap public key passed

* fix unwrap key error

* fail if both key fields have been set

* fix in extractKeyFromFields, passing a PolicyRequest wouldn't not work

* checks for read, sign and verify endpoints so they don't return errors when a private key was not imported and tests

* handle panic on "export key" endpoint if imported key is public

* fmt

* remove 'isPrivateKey' argument from 'UpdateKeyVersion' and
'parseFromKey' methods

also: rename 'UpdateKeyVersion' method to 'ImportPrivateKeyForVersion' and 'IsPublicKeyImported' to 'IsPrivateKeyMissing'

* delete 'RSAPublicKey' when private key is imported

* path_export: return public_key for ecdsa and rsa when there's no private key imported

* allow signed data validation with pss algorithm

* remove NOTE comment

* fix typo in EC public key export where empty derBytes was being used

* export rsa public key in pkcs8 format instead of pkcs1 and improve test

* change logic on how check for is private key missing is calculated

Add parsing for NSS-wrapped Ed25519 keys (#15742)
* Add parsing for NSS-wrapped Ed25519 keys

NSS wraps Ed25519 using the PKCS#8 standard structure. The Go standard
library as of Go 1.18.x doesn't support parsing this key type with the
OID used by NSS; it requires the 1.3.101.112/RFC 8410 format, rather
than the RFC 5915-esque structure supported here.

Transit byok import endpoints (#15414)
* add import endpoint

* fix unlock

* add import_version

* refactor import endpoints and add tests

* add descriptions

* Update dependencies to include tink for Transit import operations. Convert Transit wrapping key endpoint to use shared wrapping key retrieval method. Disallow import of convergent keys to Transit via BYOK process.

* Include new 'hash_function' parameter on Transit import endpoints to specify OAEP random oracle hash function used to wrap ephemeral AES key.

* Add default values for Transit import endpoint fields. Prevent an OOB panic in Transit import. Proactively zero out ephemeral AES key used in Transit imports.

* Rename some Transit BYOK import variables. Ensure Transit BYOK ephemeral key is of the size specified byt the RFC.

* Add unit tests for Transit BYOK import endpoint.

* Simplify Transit BYOK import tests. Add a conditional on auto rotation to avoid errors on BYOK keys with allow_rotation=false.

* Added hash_function field to Transit import_version endpoint. Reworked Transit import unit tests. Added unit tests for Transit import_version endpoint.

* Add changelog entry for Transit BYOK.

* Transit BYOK formatting fixes.
