7) Client computes random 2048-bit number b (using a sufficient amount of entropy) and sends the server a message
First, generate a secure random 2048-bit number b:

auth_key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

 The 128 lower-order bits of SHA1 of the byte string derived from the new_nonce string by adding a single byte with the value of 1, 2, or 3, and followed by another 8 bytes with auth_key_aux_hash. Different values are required to prevent an intruder from changing server response dh_gen_ok into dh_gen_retry.
