<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Block cipher mode of operation information. </p>
<p>Each class derived from this one defines two types, Encryption and Decryption, both of which implement the <a class="el" href="class_symmetric_cipher.html" title="Interface for one direction (encryption or decryption) of a stream cipher or cipher mode.">SymmetricCipher</a> interface. For each mode there are two classes, one of which is a template class, and the other one has a name that ends in "_ExternalCipher". The "external cipher" mode objects hold a reference to the underlying block cipher, instead of holding an instance of it. The reference must be passed in to the constructor. For the "cipher holder" classes, the CIPHER template parameter should be a class derived from <a class="el" href="struct_block_cipher_documentation.html" title="Provides Encryption and Decryption typedefs used by derived classes to implement a block cipher.">BlockCipherDocumentation</a>, for example <a class="el" href="class_d_e_s.html" title="DES block cipher.">DES</a> or <a class="el" href="class_a_e_s.html" title="AES block cipher (Rijndael)">AES</a>.</p>
<p>See NIST SP 800-38A for definitions of these modes. See <a class="el" href="struct_authenticated_symmetric_cipher_documentation.html" title="Provides Encryption and Decryption typedefs used by derived classes to implement an authenticated enc...">AuthenticatedSymmetricCipherDocumentation</a> for authenticated encryption modes. </p>
