wolfTPM version 1.5.0 was recently released, and features many new updates and additions to the wolfTPM library. Summary:

Added support for the Microchip ATTPM20 TPM 2.0 module Added Barebox bootloader support. Added TPM wrappers for HMAC, AES Key Loading. Added Benchmarking support for RNG, AES, Hashing and TLS. Improvements for TLS client/server examples and overall performance.

Detail:

Fixed issue with cleanup not unregistering the crypto callback. Added support for Microchip ATTPM20 part. Added support for Barebox (experimental). Added TLS benchmarking for CPS and KB/Sec. Enabled with TLS_BENCH_MODE. Added TLS client/server support for symmetric AES/HMAC/RNG. Enabled with WOLFTPM_USE_SYMMETRIC. Added TLS client/server support for mutual authentication. Added TIS locking protection for concurrent process access. Enabled using WOLFTPM_TIS_LOCK. Added symmetric AES encrypt and decrypt wrappers and examples. Added HMAC wrappers and examples. Added wrappers and examples for loading external HMAC and AES keys. Added delete key wrapper and example. Added ECDH support for ephemeral key generation and shared secret. Added benchmark support for RNG, AES (CTR, CBC, CFB) 128/256 and SHA-1, SHA-256, SHA-384 and SHA-512. Added new wolfTPM2_GetCapabilities wrapper API for getting chip info. Added command and response logging using ./configure –enable-debug=verbose or #define WOLFTPM_DEBUG_VERBOSE. Added option to enable raw IO logging using WOLFTPM_DEBUG_IO. Added option to disable TPM Benchmark code using NO_TPM_BENCH. Added examples/README.md for setup instructions. Tuned max SPI clock and performance for supported TPM 2.0 chips. Cleanup to move common test parameters into examples/tpm_test.h. Updated benchmarks and console output for examples in README.md.
