MBED as a Cryptographic Device

Page last updated 29 Dec 2009, by   Anders Rundgren   No tags | 0 replies  

The idea is to implement http://webpki.org/papers/keygen2/secure-key-store.pdf as a PoC (Proof-of-Concept) system.

A early version of an OpenSSL AES, SHA1, SHA256, and HMAC C++ port can be found at crypto

If you connect MBED to a terminal emulator you should get the following output:
