How to split a string into blocks of k bits long so that after a cipher/decryption cycle you get the original string (RSA)?

Question

Programming

There is an RSA encryption algorithm - https://drive.google.com/file/d/0BxCa2KoC3FpUUzVvW...
I implemented key generation.
Need help implementing string encryption/decryption.

I don't really understand why you want beats. Make the key length a multiple of 256, this is standard practice.
There is BitArray about bits, see here (in general, a good site, I recommend it).
Actually, BitArray allows you to create an array of any length. If you don't have enough characters, finish with zeros.
