@ -33,3 +33,12 @@ WARNING: This update may break previous registrations! This is because we fixed
 - Adds hmac-secret extension support. This extension is used for generating 32 or 64 byte symmetric keys using parameters from the platform and secrets on the authenticator. It's used by Windows Hello - - for offline authentication.
 - Fix bug in FIDO auth, where setting the pin requires all previous registrations to use pin. Only UV bit needs to be cleared.
 - Slightly change serial emulation USB descriptor to make it less abused by Linux Modem Manager.

+## [2.2.0] - 2019-04-17
+
+- Fixes the ordering of keys encoded in CBOR maps to be canonical ordering. They previously were not ordered in any particular way and caused issues for Chrome. #170
+- Fixes CTAP2 implementation to accept credential IDs created by the CTAP1 implementation. So registering with U2F and later authenticating with FIDO2 should work.
+
+## [2.2.1] - 2019-04-23
+
+- This minor release fixes some small issues. #179, #182

-/**
- * @class MemoryMap
- *
- * Represents the contents of a memory layout, with main focus into (possibly sparse) blocks of data.
- *<br/>
- * A {@linkcode MemoryMap} acts as a subclass of
- * {@linkcode https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Map|Map}.
- * In every entry of it, the key is the starting address of a data block (an integer number),
- * and the value is the <tt>Uint8Array</tt> with the data for that block.
- *<br/>
- * The main rationale for this is that a .hex file can contain a single block of contiguous
- * data starting at memory address 0 (and it's the common case for simple .hex files),
- * but complex files with several non-contiguous data blocks are also possible, thus
- * the need for a data structure on top of the <tt>Uint8Array</tt>s.
- *<br/>
- * In order to parse <tt>.hex</tt> files, use the {@linkcode MemoryMap.fromHex} <em>static</em> factory
- * method. In order to write <tt>.hex</tt> files, create a new {@linkcode MemoryMap} and call
- * its {@linkcode MemoryMap.asHexString} method.
- *
- * @extends Map
- * @example
- * import MemoryMap from 'nrf-intel-hex';
- *
- * let memMap1 = new MemoryMap();
- * let memMap2 = new MemoryMap([[0, new Uint8Array(1,2,3,4)]]);
- * let memMap3 = new MemoryMap({0: new Uint8Array(1,2,3,4)});
- * let memMap4 = new MemoryMap({0xCF0: new Uint8Array(1,2,3,4)});

Adam Langley	73f538dd0e	Fix COSE type of key-agreement keys. The key-agreement keys in the PIN protocol use COSE type -25. I'm not sure if that's written down anywhere, but it's what everything else does and it's an ECDH type rather than an ECDSA type.	2019-04-20 16:45:04 -07:00
Adam Langley	a5f794c0ff	Handle empty pinAuth fields. CTAP2 specifies that an empty pinAuth field is special: it indicates that the device should block for touch, i.e. it's just a way of letting a user select from multiple authenticators[1]. This change handles empty pinAuth fields in GetAssertion and MakeCredential commands. [1] https://fidoalliance.org/specs/fido-v2.0-ps-20190130/fido-client-to-authenticator-protocol-v2.0-ps-20190130.html#using-pinToken-in-authenticatorMakeCredential	2019-04-20 16:26:32 -07:00
Conor Patrick	f28cf9c6d0	new release	2019-04-18 20:41:18 -07:00
Nicolas Stalder	6a288243c1	Add Makefile for installing a HID gadget The Makefile has targets for building, installing and uninstalling a HID gadget which acts as FIDO2 authenticator. Tested on Ubuntu 18.04 but should work on other distros as well. The only assumption being made is that kernel source is available at /usr/src/linux-source-$(KERNEL_VERSION).tar.bz2. A possible improvement would be to have a configure script which finds the correct kernel source archive.	2019-04-16 10:54:49 +03:00
Radoslav Gerganov	955d4f76ef	Add support for hidg devices on Linux There is a HID gadget driver on Linux which provides emulation of USB HID devices. This could be very useful for testing the Solo firmware without actual hardware, using only a Linux box. This patch adds a command line argument which specifies whether the existing UDP backing should be used or the new one which reads and writes to /dev/hidg0. Testing done: 1. Created HID device with configfs 2. Started "./main -b hidg" as root 3. Successfully executed Webauthn registration and authentication on the same Linux machine Closes: #122	2019-04-16 10:54:46 +03:00
