CryptoAuthLib - Microchip CryptoAuthentication Library ==================================================== Introduction ------------------------ This code base implements an object-oriented C library which supports Microchip CryptoAuth devices. The family of devices supported currently are: - [ATSHA204A](http://www.microchip.com/ATSHA204A) - [ATECC108A](http://www.microchip.com/ATECC108A) - [ATECC508A](http://www.microchip.com/ATECC508A) - [ATECC608A](http://www.microchip.com/ATECC608A) Online documentation is at https://microchiptech.github.io/cryptoauthlib/ Latest software and examples can be found at: - http://www.microchip.com/SWLibraryWeb/product.aspx?product=CryptoAuthLib - https://github.com/MicrochipTech/cryptoauthtools Prerequisite skills: - strong C programming and code reading - Atmel Studio familiarity - Knowledge of flashing microcontrollers with new code - Familiarity with Microchip CryptoAuth device functionality Prerequisite hardware to run CryptoAuthLib examples: - [ATSAMR21 Xplained Pro]( http://www.microchip.com/atsamr21-xpro ) or [ATSAMD21 Xplained Pro]( http://www.microchip.com/ATSAMD21-XPRO ) - [CryptoAuth Xplained Pro Extension](http://www.microchip.com/developmenttools/productdetails.aspx?partno=atcryptoauth-xpro-b ) or [CryptoAuthentication SOIC Socket Board](http://www.microchip.com/developmenttools/productdetails.aspx?partno=at88ckscktsoic-xpro ) to accept SOIC parts For most development, using socketed top-boards is preferable until your configuration is well tested, then you can commit it to a CryptoAuth Xplained Pro Extension, for example. Keep in mind that once you lock a device, it will not be changeable. There are two major compiler defines that affect the operation of the library. - ATCA_NO_POLL can be used to revert to a non-polling mechanism for device responses. Normally responses are polled for after sending a command, giving quicker response times. However, if ATCA_NO_POLL is defined, then the library will simply delay the max execution time of a command before reading the response. - ATCA_NO_HEAP can be used to remove the use of malloc/free from the main library. This can be helpful for smaller MCUs that don't have a heap implemented. If just using the basic API, then there shouldn't be any code changes required. The lower-level API will no longer use the new/delete functions and the init/release functions should be used directly. Examples ----------- - Watch [CryptoAuthLib Documents](http://www.microchip.com/design-centers/security-ics/cryptoauthentication/overview ) for new examples coming online. - Node Authentication Example Using Asymmetric PKI is a complete, all-in-one example demonstrating all the stages of crypto authentication starting from provisioning the Crypto Authentication device ATECC608A/ATECC508A with keys and certificates to demonstrating an authentication sequence using asymmetric techniques. http://www.microchip.com/SWLibraryWeb/product.aspx?product=CryptoAuthLib Release notes ----------- 11/22/2019 - Patches for CVE-2019-16128 & CVE-2019-16129: Ensure reported packet length is valid for the packet being processed. - Improvement to encrypted read operations to allow supply of a host nonce (prevent replay of a read sequence to the host). Default API is changed but can be reverted by setting the option ATCA_USE_CONSTANT_HOST_NONCE - Added Azure compatible TNGTLS and TNGLORA certificates. Use the TNG client API to retrieve the proper certificate based on the device. - Misc Python updates (updated APIs for encrypted reads to match the C-API change) atcacert_cert_element_t now initializes properly 08/30/2019 - Added big-endian architecture support - Fixes to atcah_gen_dig() and atcah_nonce() 05/17/2019 - Added support for TNG devices (cert transforms, new API) - atcab_write_pub_key() now works when the data zone is unlocked 03/04/2019 - mbed TLS wrapper added - Minor bug fixes 01/25/2019 - Python JWT support - Python configuration structures added - Restructure of secure boot app 01/04/2019 - Added GCM functions - Split AES modes into separate files - Bug fix in SWI START driver 10/25/2018 - Added basic certificate functions to the python wrapper. - Added Espressif ESP32 I2C driver. - Made generic Atmel START drivers to support most MCUs in START. - Added AES-CTR mode functions. - Python wrapper functions now return single values with AtcaReference. - Added mutex support to HAL and better support for freeRTOS. 08/17/2018 - Better support for multiple kit protocol devices 07/25/2018 - Clean up python wrapper 07/18/2018 - Added ATCA_NO_HEAP define to remove use of malloc/free. - Moved PEM functions to their own file in atcacert. - Added wake retry to accomodate power on self test delay. - Added ca_cert_def member to atcacert_def_s so cert chains can be traversed as a linked list. 03/29/2018 - Added support for response polling by default, which will make commands return faster (define ATCA_NO_POLL to use old delay method). - Removed atcatls related files as they were of limited value. - Test framework generates a prompt before locking test configuration. - Test framework puts device to sleep between tests. - Fixed mode parameter issue in atcah_gen_key_msg(). - ATECC608A health test error code added. 01/15/2018 - Added AES-128 CBC implementation using AES command - Added AES-128 CMAC implementation using AES command 11/22/2017 - Added support for FLEXCOM6 on SAMG55 driver 11/17/2017 - Added library support for the ATECC608A device - Added support for Counter command - atca_basic functions and tests now split into multiple files based on command - Added support for multiple base64 encoding rules - Added support for JSON Web Tokens (jwt) - Fixed atcab_write_enc() function to encrypt the data even when the device is unlocked - Fixed atcab_base64encode_() for the extra newline - Updated atcab_ecdh_enc() to work more consistently 07/01/2017 - Removed assumption of SN[0:1]=0123, SN[8]=EE. SN now needs to be passed in for functions in atca_host and atca_basic functions will now read the config zone for the SN if needed. - Renamed atcab_gendig_host() to atcab_gendig() since it's not a host function. Removed original atcab_gendig(), which had limited scope. - Fixed atcah_hmac() for host side HMAC calculations. Added atcab_hmac(). - Removed unnecessary ATCADeviceType parameters from some atca_basic functions. - Added atcacert_create_csr() to create a signed CSR. - New HAL implementation for Kit protocol over HID on Linux. Please see the Incorporating CryptoAuthLib in a Linux project using USB HID devices section in this file for more information. - Added atcacert_write_cert() for writing certificates to the device. - Added support for dynamic length certificate serial numbers in atcacert. - Added atcab_write() for lower level write commands. - Fixed atcah_write_auth_mac(), which had wrong OpCode. - Added atcab_verify() command for lower level verify commands. - Added atcab_verify_stored() for verifying data with a stored public key. - Removed atcab_write_bytes_slot(). Use atcab_write_bytes_zone() instead. - Modified atcab_write_bytes_zone() and atcab_read_bytes_zone() to specify a slot - Added atcab_verify_validate() and atcab_verify_invalidate() - Improvements to host functions to handle more cases. - Added atcab_updateextra(), atcab_derive_key() - Added support for more certificate formats. - Added general purpose hardware SHA256 functions. See atcab_hw_sha2_256(). - Removed device specific config read/write. Generic now handles both. - Removed unnecessary response parameter from lock commands. - Enhanced and added unit tests. - Encrypted read and write functions now handle keys with S
