The Kryptos Sculpture contains four encypted messages.

This Challenge is to Encrypt two of the original messages for the sculptor.

The method employed is Vigenere Encryption. One clarification is that "?" are removed from the coding sequence and then re-inserted in the final encoded message.

Original phrase: Between subtle shading and the absence of light lies the nuance of iqlusion.

For coding purposes spaces and punctuation are removed, except "?".

Phrase to encode: BETWEENSUBTLESHADINGANDTHEABSENCEOFLIGHTLIESTHENUANCEOFIQLUSION

Input: Encode Phrase, Vigenere alphabet word, Vigenere shift word

Vigenere alphabet word ='KRYPTOS';

Vigenere shift word ='PALIMPSEST';

Output: EMUFPHZLRFAXYUSDJKZLDKRNSHGNFIVJYQTQUXQBQVYUVLLTREVJYQTMKYRDMFD
