<h1 id="purpose">Purpose</h1>
<ul>
<li><p><strong>STM32 Crypto Firmware Library includes a set of crypto algorithms based on firmware implementation</strong> ready to use in all STM32 series.</p></li>
<li>Cryptographic algorithms and modes supported are :
<ul>
<li>AES-128, AES-192, AES-256 bits :
<ul>
<li>FCB</li>
<li>OFB</li>
<li>XTS (Supports keys of 128 or 256 bits only)</li>
</ul></li>
<li>CHACHA20</li>
<li>CHACHA20-POLY1305</li>
<li>Curve25519</li>
<li>ED25519</li>
<li>HASH functions with HMAC support:
<ul>
<li>SHA-384</li>
<li>SHA-512</li>
</ul></li>
<li>POLY1305</li>
<li>RSA encryption/decryption with PKCS#1v1.5</li>
</ul></li>
<li><p>STM32 Crypto Firmware Library is based on modular architecture : each algorithm can be compiled with different options to manage the memory and execution speed.</p></li>
