And it should be not be seen as a replacement to the HashContent processor.Note: The underlying library loads the entirety of the streamed content into and performs result evaluations in memory. Accordingly, it is important to consider the anticipated profile of content being evaluated by this processor and the hardware supporting it especially when working against large files.</p><h3>Tags: </h3><p>hashing, fuzzy-hashing, cyber-security</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
