Conversion from Python objects to SymPy objects; Optional implicit multiplication and function application parsing; Limited Mathematica and Maxima parsing. Each crypto letter depends on two letters in the plaintext. In affine cipher each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter. Since this cipher uses pairs of characters, and there are 25 distinct characters, it is highly likely to be foursquare, bifid, playfair or some other digraphic substitution cipher based on a 5 by 5 grid.
