Jack Grigg 9503f406ae Reject identities with unrecognised critical extensions
We don't know how to correctly use these identities. In particular, some
identities store parts of their private key material in certificate
extensions to work around hardware limitations. Not understanding these
extensions could lead to encrypting with the wrong protocol and
violating security assumptions.

# Changelog
All notable changes to this crate will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to Rust's notion of
[Semantic Versioning](https://semver.org/spec/v2.0.0.html). All versions prior
to 0.3.0 are beta releases.
## [Unreleased]
## [0.3.4] - PLANNED
### Fixed
- `age-plugin-yubikey` now completely ignores any identity that has unrecognised
critical extensions in its certificate, to ensure it doesn't misuse a newer
identity type.
## [0.3.3] - 2023-02-11
### Fixed
- When `age-plugin-yubikey` assists the user in changing their PIN from the
default PIN, it no longer tells the user that PINs shorter than 6 characters
are allowed, and instead loops until the user enters a PIN of valid length.
It also now prevents the user from setting their PIN to the default PIN, to
avoid creating a cycle.
- More kinds of SmartCard readers are ignored when they have no SmartCard
inserted.
## [0.3.2] - 2023-01-01
### Changed
- The "sharing violation" logic now also sends SIGHUP to any `yubikey-agent`
that is running, to have them release any YubiKey locks they are holding.
### Fixed
- The "sharing violation" logic now runs during plugin mode as intended. In the
previous release it only ran during direct `age-plugin-yubikey` usage.
## [0.3.1] - 2022-12-30
### Changed
- If a "sharing violation" error is encountered while opening a connection to a
YubiKey, and `scdaemon` is running (which can hold exclusive access to a
YubiKey indefinitely), `age-plugin-yubikey` now attempts to stop `scdaemon` by
interrupting it (or killing it on Windows), and then tries again to open the
connection.
- Several error messages were enhanced with guidance on how to resolve their
respective issue.
## [0.3.0] - 2022-05-02
First non-beta release!
### Changed
- MSRV is now 1.56.0.
- During decryption, when asked to insert a YubiKey, you can now choose to skip
it, allowing the client to move on to the next identity instead of returning
an error.
- Certain kinds of PIN invalidity will now cause the plugin to re-request the
PIN instead of aborting: if the PIN is too short or too long, or if the user
touched the YubiKey early and "typed" an OTP.
### Fixed
- The "default" identity (provided by clients that invoke `age-plugin-yubikey`
using `-j yubikey`) previously caused a panic. It is now correctly treated as
an invalid identity (because this plugin does not support default identities).
## [0.2.0] - 2021-11-22
### Fixed
- Attempts-before-blocked counter is now returned as part of the invalid PIN
error string.
- PIN is no longer requested when fetching the recipient for a slot, or when
decrypting with a slot that has a PIN policy of Never.
- Migrated to `yubikey 0.5` to fix `cargo install age-plugin-yubikey` error
(caused by the `yubikey-piv` crate being yanked after it was renamed).
## [0.1.0] - 2021-05-02
Initial beta release.
