Bouvier's Law Dictionary, Revised 6th Ed (1856):

CONDUCT, law of nations. This term is used in the phrase safe conduct, to
signify the security given, by authority of the government, under the great
seal, to a stranger, for his quietly coming into and passing out of the
territories over which it has jurisdiction. A safe conduct differs from a
passport; the former is given to enemies, the latter to friends or citizens.
