Converting Strings to Blocks with getBlocksFromText()

rsaCipher.py

def getBlocksFromText(message, blockSize=DEFAULT_BLOCK_SIZE):

Converts a string message to a list of block integers. Each integer

represents 128 (or whatever blockSize is set to) string characters.

The getBlocksFromText() function takes the message and returns a list of blocks (that is, a
list of very large integer values) that represents the message. It is trivially easy to convert between
