For a gdb function, see http://security.stackexchange.com/a/80174/2630
To generate the line assuming you have a context with a SSL structure
(named "s") run this:
python
def read_as_hex(name, size):
addr = gdb.parse_and_eval(name).address
data = gdb.selected_inferior().read_memory(addr, size)
return ''.join('%02X' % ord(x) for x in data)
def pm(ssl='s'):
mk = read_as_hex('%s->session->master_key' % ssl, 48)
cr = read_as_hex('%s->s3->client_random' % ssl, 32)
print('CLIENT_RANDOM %s %s' % (cr, mk))
end
python pm()
