comment Decrypting a small Message using RSA with a Private Key
@e-sushi There is whole chapter in book provided on exactly this question.Person who ask also did not provide any other relevant information's on RSA like e, and this necessaries are well explained in this relatively short chapter (6 pages). I posted this link, because I was able to write such program with examples in this book long time ago.
