It serves as a tutorial for the basic hashing APIs of mbed TLS. + +## Pre-requisites + +To build and run this example you must have: + +* A computer with the following software installed: + * [CMake](http://www.cmake.org/download/). + * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows). + * [Python](https://www.python.org/downloads/). + * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded). + * A serial terminal emulator (Like screen, pySerial and cu). +* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below). +* A micro-USB cable. +* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration). + +## Getting started + +1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board. + +2. Navigate to the mbedtls directory supplied with your release and open a terminal. + +3. Set the yotta target: + + ``` + yotta target frdm-k64f-gcc + ``` + +4. Build mbedtls and the examples. This may take a long time if this is your first compilation: + + ``` + $ yotta build + ``` + +5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-hashing.bin` to your mbed board and wait until the LED next to the USB port stops blinking. + +6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. + + Use the following settings: + + * 115200 baud (not 9600). + * 8N1. + * No flow control. + +7. Press the Reset button on the board. + +8. The output in the terminal window should look like: + + ``` + {{timeout;10}} + {{host_test_name;default}} + {{description;mbed TLS example on hashing}} + {{test_id;MBEDTLS_EX_HASHING}} + {{start}} + + + Method 1: 315f5bdb76d078c43b8ac0064e4a0164612b1fce77c869345bfc94c75894edd3 + Method 2: 315f5bdb76d078c43b8ac0064e4a0164612b1fce77c869345bfc94c75894edd3 + Method 3: 315f5bdb76d078c43b8ac0064e4a0164612b1fce77c869345bfc94c75894edd3 + Method 4: 315f5bdb76d078c43b8ac0064e4a0164612b1fce77c869345bfc94c75894edd3 + + DONE + {{success}} + {{end}} + ``` |
