Esp sha hmac
SHA-1 generates a fixed size output of 20-bytes for an arbitrarily long message; but so does an HMAC when it uses SHA-1. 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.

For whatever reason, you've chosen to manually key the beast — perhaps you hate yourself. HMAC var sha_ob = new jsSHA('SHA-Type', 'Input_Type'); sha_ob.setHMACKey('my_key', 'TEXT'); sha_ob.update('Add your text'); var hmac = sha_ob.getHMAC('HEX'); 1. Instantiate a new jsSHA() object the same way as for hashing. 2. Then set the HMAC key to be used by calling sha_ob.setHMACKey() with the key (here 'my_key'), and its input type (here transform: esp-aes esp-sha-hmac , in use settings ={Tunnel, } conn id: 2005, flow_id: NETGX:5, sibling_flags 80000046, crypto map: CMAP sa timing: remaining key lifetime (k/sec): (4382614/3303) IV size: 16 bytes replay detection support: Y Status: ACTIVE spi: 0x53229582(1394775426) transform: esp-aes esp-sha-hmac , in use settings ={Tunnel, } * HMAC is initialized with a key and an underlying hash function; it * then fills a "key context".

AH and ESP are both protocols, you can use them for ipsec vpn. HMAC can be included with either ESP or AH. Check the sample transform sets as per documents I provided to you previously. The HMAC (Hash-based Message Authentication Code) module provides hardware acceleration for SHA256-HMAC generation using a key burned into an eFuse block. HMACs work with pre-shared secret keys and provide authenticity and integrity to a message.
