MPLAB® Harmony 3.0 Tutorial: Basics 12

In order to help you use the latest version of MPLAB® Harmony 3 software framework, our 32-bit product department experts have written a series of tutorials . Today, we recommend the twelfth tutorial.

Harmony 3 provides a C language interface cryptographic library for embedded applications, including encryption, decryption, hash functions, authentication and compression functions, as well as random number generation (RNG) functions.

The main functions of the encryption library are:

• Block Ciphers: DES, 3DES and AES are provided to meet the needs of block ciphers. CBC and CTR modes are supported depending on the algorithm used.

• Public Key Cryptography: Provides RSA and Elliptic Curve Cryptography (ECC) for public key cryptography, and Diffie-Hellman (DH) for key agreement arrangements.

• Hash Functions: Provides MD5, SHA, SHA-256, SHA-384, and SHA-512 hash functions. These functions do not require a key or initialization vector (IV).

• Random Number Generation Functions: This library provides functions for generating a single pseudo-random number or a set of pseudo-random numbers.

  
  

  This article will introduce how to use this encryption library.
