Rolling Encryption for Groundside Announcements

When the groundside comms relays are offline, squad and command announcements will become increasingly garbled over time. You can use the encryption computers to restore the announcement clarity; however, clarity once restored will still decay over time until the comms relays are brought back online.

To use these computers, you must be trained (level 1 or higher) in the Intel skill. This includes command, senior command, auxiliary support officers, and research staff.

These exact values can vary, but normally, announcements lose 2.5% clarity every 30 seconds when comms are down. The minimum clarity is 45%, which happens after 10 minutes without comms or encryption. Clarity can be restored to a maximum of 95%.

Purple	Encryption Decoder Computer	This generates a challenge token from the current encryption stream. Use the "Decode Current Stream" button to generate the encryption challenge token. Click the print button at the top right to punch and print the challenge token onto a punchcard. OR manually enter the challenge token into the Cipher Computer's input by entering the decimal that corresponds to the desired hex.
Blue	Encryption Cipher Computer	This decrypts codes using a cipher phrase to create an encoded challenge phrase. Insert the challenge token punchcard into the Cipher Computer. OR manually enter the challenge token in the top input section from the Decoder Computer. Use the less-than "<" and greater-than ">" symbols to cycle through the options until you decipher the challenge token into a word. If you inserted a punchcard and none of the settings create a word, then there may be a character that was incorrectly punched as a zero. This results in you almost getting a word, but having one letter (the erroneous zero) wrong. You can fix this by clicking and dragging up or down on the mispunched zero to adjust it to its proper value or manually entering the correct value from the Decoder Computer. Once you have found the cipher word, note the "cipher setting," which will be a number between 0 and 26. Use the print button at the top right to print the output of the deciphered challenge token onto a punchcard. OR manually enter the output to the Encoder Computer.
Red	Encryption Encoder Computer	This uploads encoded phrases to restore announcement clarity. Insert the deciphered challenge token punchcard into the Encoder Computer. OR manually enter in the Cipher Computer's output. Set the nob on the left to the "cipher setting" from the Cipher Computer. Use the "Submit New Encoding" button to test your decrypted challenge token. If your "PING" generates a "PONG," then announcement clarity has been restored to maximum clarity (normally 95%). If your "PING" only generates a partial "PONG," then too much time has passed. This means your token is partially out of date, but announcement clarity is still partially restored. If you input a deciphered challenge token punchcard, then there is a chance that one character was incorrectly punched as a zero. This will cause your PING to completely fail. You can fix this by clicking and dragging up or down on the mispunched zero to adjust it to its proper value or manually enter the correct value.
White	Punchcards	To check approximately how much announcement clarity you have, submit the last successful decipher challenge token. The number of "PONG" letters you have indicates the clarity: 4 letters means >90% clear. 3 letters means >75% clear. 2 letters means >60% clear. 1 letter means >45% clear. 0 letters means 45% clear. The Decoder and Cipher Computers each start loaded with 10 punchcards. Four punch card stacks are on the table in front of the computers, and each stack contains five punchcards. You can insert a punchcard stack into the computers to refill them, and hover over the "print" button to check how many punchcards the computer has left. More punchcard stacks can be found on the ground by Intelligence Officers.
