<DL>
<DD>Sets the modulus value of the key.
 The plain text data format is big-endian and right-aligned (the least significant bit is the least significant
 bit of last byte). Input modulus data is copied into the internal representation.
 <p>Note:<ul>
 <li><em>If the key object implements the </em><code>javacardx.crypto.KeyEncryption</code><em>
 interface and the </em><code>Cipher</code><em> object specified via </em><code>setKeyCipher()</code><em>
 is not </em><code>null</code><em>, the modulus value is decrypted using the </em><code>Cipher</code><em> object.</em>
