The principle is very simple:
Byte Set 1 (n-bit random byte set) Byte Set 2 (m-bit random byte set)
Encrypted byte set = Byte set 1 + Encrypted byte set + Byte set 2
Byte set after encrypted word = encryption (encrypted byte set, password)
Decrypted byte set = decrypted (decrypted byte set, password)
Decrypted byte set = byte set 1 + encrypted byte set + byte set 2
Decrypted byte set = get between byte set (decrypted byte set, n+1, get the byte set length (decrypted byte set) -m-n)
