Introduction

The following demonstration describes the large hash functionality of the crypto module.

Description

This application demonstrates how to execute hashes on large blocks of data. In this case, the demonstration performs MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashing on a 512 * 1024 block of the letter ‘a’. After the hashing has been performed, the application outputs via the system console the results of the hashing, and the time it took to perform each form. It then compares the generated hashes with known values for each algorithm. If all tests pass a message is presented through the system console. If any tests fail a corresponding message is presented through the system console.

Building the Application

To build this project, the project corresponding to the functionality desired must be opened in MPLAB X IDE or the IAR IDE. The following tables list and describe the project and supported configurations. The parent folder for these files is crypto/apps/large_hash/firmware.

  1. Once the project is loaded, click on Project in the Main Toolbar.
  2. Click on Make under the Project menu to build the demo.

Configuring the Hardware

Refer to the following pages to configure the hardware:

Running the Demostration

  1. First connect the board to the PC as described in the ‘Configuring the Hardware’ section.
  2. Configure a terminal application (ex. Tera Term) to access the newly attached serial port. The parameters to use:
    • 115,200 bps
    • 8 data bits
    • no parity
    • 1 stop bit
    • no flow control
  3. Compile the demostration
    • For MPLAB X
      1. Use the standard MPLAB X IDE Buttons
    • For IAR
      1. Once the build is completed, in an explorer window, go to …\crypto\apps\encrypt_decrypt\firmware\sam_a5d2_xplained_ultra_sw.IAR\Debug\Exe
      2. Copy the harmony.bin file onto an SD card
      3. Copy the boot.bin file onto the SD card from here
      4. Insert the SD card into the card connector on the SAMA5D2 board.
      5. Press the reset button on the board
  4. Observe the output from the serial console. An example is shown in the following figure. Each project will have different timing results.
