The militant group said the drafting of the document started before Israel's assassination of Hamas founder and spiritual guide Sheik Ahmed Yassin last March.
The pact stresses Israel as the Palestinians' main enemy and calls for continued opposition by any means "be they military, security, political and economic."
The document calls for the establishment of an independent Palestinian state with Jerusalem as its capital and underscored the legitimacy of the "armed resistance.
It bans any cooperation, security coordination and contacts with Israeli occupation forces as a crime subject to severe punishment. The document did not specify whether that included the contacts between the Palestinian Authority and Israel.
"The issue of liberating the prisoners and detainees in Israel is a priority in the Palestinian struggle and part of Palestinian sovereignty and liberation," the document said.
It also called for combating corruption and waste, and streamlining national resources and revenues.
