HMAC-SHA256 or HMAC-SHA3-256). HMAC-SHA-1-96 produces a 160-bit authenticator value. For use with either ESP or AH, a truncated value using the first 96 bits MUST be supported. Upon sending, the truncated value is stored within the authenticator field. Within the solid circles in Figure 13-7, esp-3des defines the encryption algorithm, while esp-sha-hmac defines the authentication algorithm. These parameters must be the same for both peers. Within the IPsec transform set, the IPsec mode can be configured.
