<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>The Common Encryption spec provides for subsample encryption, where portions of a sample are not encrypted. A <a class="el" href="../../d1/d34/structshaka_1_1media_1_1SubsampleEntry.html">SubsampleEntry</a> specifies the number of clear and encrypted bytes in each subsample. For decryption, all of the encrypted bytes in a sample should be considered a single logical stream, regardless of how they are divided into subsamples, and the clear bytes should not be considered as part of decryption. This is logically equivalent to concatenating all <em>cipher_bytes</em> portions of subsamples, decrypting that result, and then copying each byte from the decrypted block over the corresponding encrypted byte. </p>
