SHA is more resistant to brute-force attacks than MD5, however it is slower.

zMD5: A one-way hashing algorithm that produces a 128−bit hash.

zSHA: A one-way hashing algorithm that produces a 160−bit hash.

~IKE key group (Diffie-Hellman key length): It is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.
