interface Tunnel0 ip address HMAC stands for hashed message authentication code and is an important factor in VPN security. Learn why strong HMAC auth matters for VPN security. Typical way to use hmac, construct an HMAC object from your key, message and  def create_sha256_signature(key, message): byte_key = binascii.unhexlify(key) message Consider the following configuration on a Cisco ASA: crypto ipsec transform-set ESP-DES-SHA esp-des esp-sha-hmac What is the purpose of this command? crypto ipsec transform-set ESP-DES-SHA esp-des esp-sha-hmac.

HMAC-SHA1-96 = HMAC using SHA-1 hash function with mac truncated to 96 bits. The benefits of HMAC truncation are discussed in FIPS PUB 198-1 , chapter 5. For HMAC-SHA1 96 bits is very common truncation, used for instance by IPsec/ESP.
