Usage

HAMC-SHA1:

var signature = HMACSHA1HashingProvider.Signature("image", "alexinea");

DES without salt:

var s = DESEncryptionProvider.Encrypt("image", "alexinea", "forerunner");
Assert.Equal("fJ2yrnAPaH0=", s);

var o = DESEncryptionProvider.Decrypt(s, "alexinea", "forerunner");
Assert.Equal("image", o);

DES with salt:

var s = DESEncryptionProvider.Encrypt("image", "alexinea", "forerunner", "123412341234");
Assert.Equal("s4h5u8hA/2Y=", s);

var o = DESEncryptionProvider.Decrypt(s, "alexinea", "forerunner", "123412341234");
Assert.Equal("image", o);

DES with salt and autokey

var key = DESEncryptionProvider.CreateKey();
var s = DESEncryptionProvider.Encrypt("image", key.Key, key.IV, "123412341234");
var o = DESEncryptionProvider.Decrypt(s, key.Key, key.IV, "123412341234");
Assert.Equal("image", o);
