WebAbout Diffie-Hellman Groups. Diffie-Hellman (DH) groups determine the strength of the key used in the key exchange process. Within a group type (MODP or ECP), higher Diffie-Hellman group numbers are usually more secure. ... In addition to Phase 1, you can also specify the Diffie-Hellman group to use in Phase 2 of an IPSec connection. Phase 2 ... WebCryptography FAQ, section 3.6.1 [2], What is Diffie-Hellman [3], Diffie-Hellman Method for Key Agreement [4], and PKCS #3: Diffie-Hellman Key-Agreement Standard [5]. Note that some of these numbers are very large for example, if p is a 512 bit binary number, the minimum allowed in the standard, that would be a number with up to 150+ digits
