Hashing is used to verify integrity, making sure the media has not been altered, changed, or modified by accidental or intentional means. Hashing can also be called a checksum or message digest. I would use HMAC-SHA256.

IPsec performs ESP protocol encapsulation using the SHA-1 hash function with HMAC message authentication. SHA-1 is considered stronger than MD5. The keywords listed below can be used with the ike and esp directives in ipsec.conf or the proposals settings in swanctl.conf to define cipher suites. Step 5: Configure the IKE Phase 2 IPsec policy on R1. a. Create the transform-set VPN-SET to use esp-aes and esp-sha-hmac. crypto ipsec transform-set NAME esp-aes 256 esp-sha512-hmac mode transport  My point is that isn't it true to use the ah-sha512-hmac rather than the esp-sha512-hmac?
