Microchip offers a reliable security solution for 
embedded applications built on the dsPIC30F platform. 
This solution is provided by means of two libraries – 
Symmetric Key and Asymmetric Key Embedded 
Encryption Libraries. The Symmetric Key Library 
features the following:

• Hash Functions:

- SHA-1 Secure Hash Standard

- MD5 Message Digest

• Symmetric Key Encryption/Decryption Functions:

- Advanced Encryption Standard (AES)

- Triple Data Encryption Algorithm

(Triple-DES)

• Random Number Generator Functions:

- Deterministic Random Bit Generator 

ANSI X9.82

• C-callable library functions developed in 

MPLAB

® 

ASM30

• Assembly language

• Optimized for speed, code size and RAM usage:

- RAM usage below 60 bytes

• Library functions extensively tested for 

adherence to applicable standards

• Symmetric Key Encryption/Decryption functions 

support multiple modes of operation:

- Electronic Code Book (ECB) mode

- Cipher Block Chaining with Message 

Authentication (CBC-MAC) mode

- Counter (CTR) mode

- Combined CBC-MAC and Counter (CCM) 

mode

• A comprehensive 

“dsPIC30F Embedded 

Encryption Libraries User’s Guide” describing the 
required APIs for the library functions

• Several examples of use are provided for each 

library function
