<p>EVP_CIPHER-NULL - The NULL EVP_CIPHER implementation</p>

|
<h1 id="DESCRIPTION">DESCRIPTION</h1>
|
||
|
|
|
||
|
|
<p>Support for a NULL symmetric encryption using the <b>EVP_CIPHER</b> API. This is used when the TLS cipher suite is TLS_NULL_WITH_NULL_NULL. This does no encryption (just copies the data) and has a mac size of zero.</p>
