我正在为学校做一项工作,我必须实现rsa生成公钥/私钥和加密/解密二进制消息.我已经生成了公钥/私钥,但我的加密/解密功能不起作用.我没有得到任何执行错误,但是当我解密时,我加密的消息不一样.
我加密块的代码:
def encrypt_block(block,block_size,e,n):
number = int(block,2) #convert to decimal number
cipher_number = pow(number,e,n) #method for fastest exponentiation number^e mod n
cipher_size = len(bin(cipher_number)) - 2
tmp_text = '{0:b}'.format(cipher_number)
while(len(tmp_text)<block_size): #add zeros to left to fill until block_size
tmp_text = "0" + tmp_text
return tmp_text

我的加密代码:
block_size = len(bin(n-1)) - 2 #size of encrypted blocks
text_size = block_size - 5 #size of clear text blocks
tmp_text = "" #variable for holding current block
encrypted_message = ""

我得到异常的代码就是这个:
using (System.Drawing.Image imgOriginal = System.Drawing.Image.FromFile(sOriginalPath, true))
{
using (System.Drawing.Image imgLogo = System.Drawing.Image.FromFile(sLogoPath, true)) //This is where it throws the exception
{
using (Graphics gra = Graphics.FromImage(imgOriginal))
{
Bitmap bmLogo = new Bitmap(imgLogo);
int nWidth = bmLogo.Size.Width;
int nHeight = bmLogo.Size.Height;
int nLeft = (imgOriginal.Width / 2) - (nWidth / 2);
int nTop = (imgOriginal.Height / 2) - (nHeight / 2);
gra.DrawImage(bmLogo, nLeft, nTop, nWidth, nHeight);
}
return imgOriginal;
