The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid. The example key shows one way the letters can be assigned to the grid.
T3 or T3R - Tier 3 or Tier 3 Reinvestigation, now replace all NACLC. T5 and T5R - Tier 5 or Tier 5 Reinvestigation, now replace SSBI and SBPR respectively. Yankee White – An investigation required for personnel working with the President and Vice President of the United States. Obtaining such clearance requires, in part, an SSBI.
A pamphlet published in 1885, entitled The Beale Papers, is the source of this story.The treasure was said to have been obtained by an American named Thomas J. Beale in the early 1800s, from a mine to the north of Nuevo México (New Mexico), at that time in the Spanish province of Santa Fe de Nuevo México (an area that today would most likely be part of Colorado).
Do Not Believe His Lies: The Unforgiving Riddle is an interesting, sometimes weird, puzzle game where players have to figure out what the code to unlock the next puzzle is. There is very little in ...
Google also announced Gmail on April 1, with an unprecedented and unbelievable free 1 GB space, compared to e.g. Hotmail's 2 MB. The announcement of Gmail was written in an unserious jokey language normally seen in April Fools' jokes, tricking many into thinking that it was an April Fools' joke.
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .
Four-square cipher. The four-square cipher is a manual symmetric encryption technique. [1] It was invented by the French cryptographer Felix Delastelle . The technique encrypts pairs of letters ( digraphs ), and thus falls into a category of ciphers known as polygraphic substitution ciphers. This adds significant strength to the encryption when ...
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the ...
