Certainly propaganda needs positive aspects as well:
The art of circulating positive images even if the actual situation is unsuccessful, like in a war or before elections, when all opinion-polls are negative, is one which needs talent.

Established in 1950, the National Science Foundation is an independent agency of the U.S. government dedicated to the funding in basic research and education in a wide range of sciences and in mathematics and engineering. Today, the NSF supplies about one quarter of total federal support of basic scientific research at academic institutions.

The Clipper Chip is a cryptographic device proposed by the U.S. government that purportedly intended to protect private communications while at the same time permitting government agents to obtain the "keys" upon presentation of what has been vaguely characterized as "legal authorization." The "keys" are held by two government "escrow agents" and would enable the government to access the encrypted private communication. While Clipper would be used to encrypt voice transmissions, a similar chip known as Capstone
would be used to encrypt data. The underlying cryptographic algorithm, known as Skipjack, was developed by the National Security Agency (NSA).
The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys.
