Cipher Mail

Cipher Mail (暗号メール) is a system from the Mega Man Star Force series that allows one to obtain a reward by sending a code via mail. In Mega Man Star Force, the Cipher Mail is a secret system that Omega-Xis discovers by looking at Geo Stelar's Transer. The message is sent to the Satellite Admin in the first game and to Legendary Master Shin in Mega Man Star Force 2. In the mail menu, compose a mail to the admin or Shin with the subject "Cipher" (あんごう) and the cipher text in the message. The codes must be written exactly as they appear, otherwise it will not work.

In Mega Man Star Force 3 it is changed to the Cipher Code (暗号コード) system, the code being given to Ken Suther's Wizard, Hang Ten, instead of being sent by mail. Hang Ten needs Cipher Codes to master giant Noise Waves in the EM ocean.
