Characters to numbers

I’m experimenting with the way of converting a string into a big integer representation. And this is how I’m doing it:

  1. Convert each character to its ASCII number, then treat them as a sequence of numbers that becomes a big number. For example, if the text is “CRYPTO” then the number will be “678289808479”. This number then will be stored in a FIELD2N variable. [done]
  2. The number then calculated to check if it fits on the curve. If not, add 1 to the next byte outside the bytes used for storing data. Repeat until the value fits in. [to be done next]

Here’s some result:
