The HMAC algorithm provides a framework for inserting various hashing algorithms such as SHA-1. HMAC-SHA-1-96 operates on 64-byte blocks of data. Padding requirements are specified in [ FIPS-180-1] and are part of the SHA-1 algorithm.

Mark as New; Para ello, calcula un Hash Message Authentication Code (HMAC) a través de algún algoritmo hash operando sobre una clave secreta, el contenido del paquete IP y las partes inmutables del datagrama. Este proceso restringe la posibilidad de emplear NAT, que puede ser implementada con NAT transversal.
