The key is invariably equal to the message-length but that is just in

In situations where that's acceptable we just use OTP.  OTP is nice

Does this mean you have a computerised working one-time pad ? I am
very interested because I have recently completed just such a one time
pad that uses the ASCII set as a Vigenere square - the ensuing
ciphertext is alphanumeric => it is immune to lexical, arithmetical
and all numerical analysis - randomness is assured hence it qualifies
for theoretically unbreakable class.

I have noticed in the course of writing six ciphers, 4 are skew-line
vector based, 1 is skewcurve vector-based, the other is the OTP above
that the sheer act of programming is trending towards ciphers that all
have the OTP property, namely the key length equals the messagelength
by necessity which of course is leading towards possible state of all
one-time pads in future computerised ciphers.

Care to tell us about yours ? who is we in your posting ? - thanks -
