Hash File: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

Computing the hash for a file of any size.

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

//  Any string argument automatically begins the 30-day trial.

//  There is  no size limitation because the file is consumed
//  in streaming mode internally.
string filename;

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

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

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

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

//  Hash using MD5
crypt.HashAlgorithm = "md5";

//  Hash using SHA-256
crypt.HashAlgorithm = "sha256";

textBox1.Text += hash + "\r\n";

//  Hash using SHA-384
crypt.HashAlgorithm = "sha384";

//  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
