<p>In general, a minimum key size of <strong>2048</strong> bits is recommended for both. It provides 112 bits of security. A key length of
<strong>3072</strong> or <strong>4096</strong> should be preferred when possible.</p>
<h4>AES (Advanced Encryption Standard)</h4>
<p>AES supports three key sizes: 128 bits, 192 bits and 256 bits. The security of the AES algorithm is based on the computational complexity of trying
all possible keys.<br> A larger key size increases the number of possible keys and makes exh
