in AND if there is a 0 the value becomes 0. In boolean expression if there is a false it is already false
Example
001
111
Answer
001
Example
H0 - 01100111010001010010001100000001
H1 - 11101111110011011010101110001001
Answer
01100111010001010010001100000001
In OR if there is a true statement it is already true. If there is 1 it becomes 1
Example
011
111
Answer
111
Example
H2 - 10011000101110101101110011111110
H3 - 00010000001100100101010001110110
Answer
10011000101110101101110011111110
In NOT you are going to reverse the particular value. If this is true the value becomes false.
Example
0
Answer
1
Example
H4 - 11000011110100101110000111110000

I hope this will help you to enlighten.
Before I create a simple hashing using SHA-256
Code:
Random r = new Random();
char[] codes = "abcdefghijklmnopqrstuvwzyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToArray();
string output;
void generateKey(int gkey)
{
output = null;
for (int x = 0; x < codes.Length; x++)
{
output += codes[r.Next(0, codes.Length)];
}
t1bx.Text = output;
}
private void B_generate_Click(object sender, RoutedEventArgs e)
{
generateKey(10);
}
static string ComputeSha256Hash(string rawData)
{
// Create a SHA256
using (SHA256 sha256Hash = SHA256.Create())
{
// ComputeHash - returns byte array
byte[] bytes = sha256Hash.ComputeHash(Encoding.UTF8.GetBytes(rawData));
// Convert byte array to a string
StringBuilder builder = new StringBuilder();
for (int i = 0; i < bytes.Length; i++)
{
builder.Append(bytes[i].ToString("x2"));
}
return builder.ToString();
}
}
private void B_hash_Click(object sender, RoutedEventArgs e)
{
txtbx_hash.Text = ComputeSha256Hash(output);
}
char[] codes = "abcdefghijklmnopqrstuvwzyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToArray();
string output;
void generateKey(int gkey)
{
output = null;
for (int x = 0; x < codes.Length; x++)
{
output += codes[r.Next(0, codes.Length)];
}
t1bx.Text = output;
}
private void B_generate_Click(object sender, RoutedEventArgs e)
{
generateKey(10);
}
static string ComputeSha256Hash(string rawData)
{
// Create a SHA256
using (SHA256 sha256Hash = SHA256.Create())
{
// ComputeHash - returns byte array
byte[] bytes = sha256Hash.ComputeHash(Encoding.UTF8.GetBytes(rawData));
// Convert byte array to a string
StringBuilder builder = new StringBuilder();
for (int i = 0; i < bytes.Length; i++)
{
builder.Append(bytes[i].ToString("x2"));
}
return builder.ToString();
}
}
private void B_hash_Click(object sender, RoutedEventArgs e)
{
txtbx_hash.Text = ComputeSha256Hash(output);
}
I hope this will help you how to make a sha.
