NAME

SYNOPSIS

DESCRIPTION

cipherProc configure ?options?

Configure the settings for the foursquare cipher. Valid options are:

cipherProc configure -ciphertext string

cipherProc configure -ct string

Set the ciphertext for this cipher instance to string. Invalid letters or numbers in the ciphertext are silently discarded.

cipherProc configure -language language

This option is currently ignored for all cipher types. Set the current cipher language to language. If the cipher has a solve method then digram frequencies for this language are used to determine the best fit. If the language is not specified or not known then english is used.

cipherProc cget option

Look up the value for a given option. Valid options are:

cipherProc cget -type

Returns the type of this cipher. In this case, foursquare

cipherProc cget -ciphertext

cipherProc cget -ct

Return the ciphertext for this cipher.

cipherProc cget -plaintext

cipherProc cget -pt

Return the plaintext for this cipher based on the current key setting.

cipherProc cget -key

Returns the current key setting for this cipher. The result can be passed back to this cipher instance or another cipher with the cipherProc restore subcommand.

cipherProc cget -length

Returns the length of the ciphertext for this cipher. 0 is returned if the ciphertext has not been set.

cipherProc cget -period

Return the period for this cipher.

cipherProc cget -language

Returns the name of the language used for this cipher.

cipherProc restore key

The restore command restores the cipher's key to a previously stored state. The output from cipherProc cget -key can be passed back into the restore command to implement a crude save feature. Example:

set key [$firstCipher cget -key]
$secondCipher restore [lindex $key 0] [lindex $key 1]
