Security And Freedom Through Encryption: ======================================= This patch adds a Law Enforcement Access Field to PGP 2.6.3i, which can be used to provide, upon presentment of a court order, immediate access to plaintext data. This tool will frustrate illegal and deadly activity of terrorist groups that plot to blow up buildings, drug cartels that seek to poison our children, and those who proliferate in deadly chemical and biological weapons, and will bring international criminals to justice.
