Added pre-computed DH params for fallback values for 4096 and 8192 bit sizes, in addition to 2048 check-in: 6286921174 user: rkeene tags: trunk
14:39
Updated gen_dh_params to support specifying a number of bits -- currently the only supported value is 2048 check-in: b128e0d4e4 user: rkeene tags: trunk
