úÎûJBase45 encoding/decoding SafeÿEncodes binary data into a String. The resulting string will contain only the 45 characters allowed by the qr-code alphanumeric mode. The binary data to be encoded should be represented as a Haskell Integer. To convert a ByteString to a Haskell Integer you can use the  function defined bellow.xConverts a BinaryString to an Integer. This is used to represent binary data as a Haskell Integer tha can be passed to  function defined above.fDecodes binary data from its text representation. The text representation of data, obtained with the ñ function defined above, will contain only characters allowed in the qr-code alphanumeric mode. The decoded binary data returned by this function will be represented as a Haskell Integer. To convert it into a BinaryString you can use the  function defined bellow.Converts a Haskell Integer into a ByteString. The Integer holds the binary represantation of the data you obtain by using the w function defined above. You can use the ByteString represantation to, for example, save the binary data into a file.
