project Key in the vigenere functions (both)

12:54pm Mon 6th May, Arran S.

Hi,

I'll amend the spec to clarify this: the key must fall in the "encryptable range" specified by range_low and range_high. For each letter of the plaintext which is to be encrypted, we work out an appropriate caesar cipher by subtracting low_range from the current letter of the keystream. So it probably wouldn't be ideal to allow key characters outside that range. (Though I guess one could just modulo them with the alphabet size, if one wanted an API like that.)

Whether they can have spaces or punctuation in them will depend entirely on what range has been specified by the caller.

Does that clarify things?

Cheers

Arran

Can the key for the Vigenere encrypt and decrypt functions have spaces or punctuation characters in it? Or does it have to be a stream of alphabets? The project spec doesn't mention anything about this..
