![]() On windows, you can just put it in the same folder as your PHP binary. The program takes the size of the prime number p in the specified bit range. The value of a selected by Alice: 2016295672 The Diffie-Hellman protocol is a method for two computer users to generate a shared private key with which they can then exchange information across an insecure channel. The value of b selected by Bob: 1146783380 Diffie-Hellman is a way of generating a shared secret between two people in such a way that the secret can’t be seen by More. First, they agree on two prime numbers g and p, where p is large (typically at least 512 bits) and g is a primitive root modulo p. The value of B sent to Bob by Alice: 287287597 The value of A sent to Bob by Alice: 591592312 Hello there, I think I can help you in that calculation. ![]() It would be possible to leave the cipher suites which use Diffie-Hellman key exchange enabled, and extend their key size from the default 1,024 bits to 2,048 bits. This is free and unencumbered software released into the public domain for educational purposes. This would protect against Logjam and similar attacks. However, calculating a 2,048 key size is about 5 times more computationally intensive than a 1,024 bit key size.
