DESCRIPTION

genboard filename type ?period?

Rewriting a cipher into a layout that is more useful for hand solving can be a tedious and error prone operation. This program is used to read ciphertext from a file and format it in a way that can be printed out for hand solving. The type argument must be one of the supported types:

• homophonic
• twosquare
• phillips
• playfair
• foursquare
• fmorse (Fractionated Morse)
• trisquare
• bifid
• cmbifid (Conjugated Matrix Bifid)
• bigbifid (6x6 Bifid)
• trifid
• quagmire1
• quagmire2
• quagmire3
• quagmire4
• ragbaby
• gromark (Use the period argument to set the primer)
• nicodemus

The period argument must be used with the periodic ciphers such as quagmires and nicodemus. Use the period argument to set the primer for a gromark cipher.

Here is a sample layout for a gromark cipher:
