Purpose

STM32 Crypto Firmware Library includes a set of crypto algorithms based on firmware implementation ready to use in all STM32 series.
Cryptographic algorithms and modes supported are :
- AES-128, AES-192, AES-256 bits :
  - FCB
  - OFB
  - XTS (Supports keys of 128 or 256 bits only)
- CHACHA20
- CHACHA20-POLY1305
- Curve25519
- ED25519
- HASH functions with HMAC support:
  - SHA-384
  - SHA-512
- POLY1305
- RSA encryption/decryption with PKCS#1v1.5
STM32 Crypto Firmware Library is based on modular architecture : each algorithm can be compiled with different options to manage the memory and execution speed.

For mode details about STM32 Crypto Firmware Library, please refer to UM1924.
