Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

//  Any string argument automatically begins the 30-day trial.
bool success;
success = crypt.UnlockComponent("30-day trial");
if (success != true) {
    MessageBox.Show("Crypt component unlock failed");
    return;
}

string s;
s = "The quick brown fox jumps over the lazy dog";

crypt.HashAlgorithm = "sha1";
crypt.EncodingMode = "hex";

//  Other possible EncodingMode settings are:
//  "quoted-printable", "base64", and "url"

string hash;
hash = crypt.HashStringENC(s);
textBox1.Text += "SHA1:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Hash using MD2
crypt.HashAlgorithm = "md2";
hash = crypt.HashStringENC(s);
textBox1.Text += "MD2:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Hash using MD5
crypt.HashAlgorithm = "md5";
hash = crypt.HashStringENC(s);
textBox1.Text += "MD5:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

//  Hash using SHA-256
crypt.HashAlgorithm = "sha256";
hash = crypt.HashStringENC(s);
textBox1.Text += "SHA256:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Hash using SHA-384
crypt.HashAlgorithm = "sha384";
hash = crypt.HashStringENC(s);
textBox1.Text += "SHA384:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Hash using SHA-512
crypt.HashAlgorithm = "sha512";
hash = crypt.HashStringENC(s);
textBox1.Text += "SHA512:" + "\r\n";
textBox1.Text += hash + "\r\n";

//  Hash using HAVAL
//  There are two additional properties relevant to HAVAL:
//  HavalRounds, and KeyLength.
//  HavalRounds can have values of 3, 4, or 5.
//  KeyLength can have values of 128, 160, 192, 224, or 256
crypt.HashAlgorithm = "haval";
crypt.HavalRounds = 5;
crypt.KeyLength = 256;
hash = crypt.HashStringENC(s);
textBox1.Text += "Haval:" + "\r\n";
textBox1.Text += hash + "\r\n";
