MD5

var apple = "apple";
var md5String = apple.ToMd5String();
var md5Bytes = apple.ToMd5();

SHA

var apple = "apple";
//D0BE2DC421BE4FCD0172E5AFCEEA3970E2F3D940
var sha1String = apple.ToSha1String();
var sha1Bytes = apple.ToSha1();

var sha256String = apple.ToSha256String();
var sha256Bytes = apple.ToSha256();

var sha512String = apple.ToSha512String();
var sha512Bytes = apple.ToSha512();

AES

var original = "Here is some data to encrypt!";
var key = AesHelper.GenerateKey();
var vector = AesHelper.GenerateVector();
//Default cipher mode is CBC and padding mode is PKCS7.
var encrypt = original.EncryptByAes(key, vector); // Also you can use Helper like this: AesHelper.Decrypt(encrypt, key, vector);
var decrypt = encrypt.DecryptByAes(key, vector); // Also you can use Helper like this: AesHelper.Decrypt(encrypt, key, vector);
var decryptString = Encoding.UTF8.GetString(decrypt);

RC2

var original = "Here is some data to encrypt!";
var key = Rc2Helper.GenerateKey();
var vector = Rc2Helper.GenerateVector();
//Default cipher mode is CBC and padding mode is PKCS7.
var encrypt = original.EncryptByRc2(key, vector); // Also you can use Helper like this: Rc2Helper.Decrypt(encrypt, key, vector);
var decrypt = encrypt.DecryptByRc2(key, vector); // Also you can use Helper like this: Rc2Helper.Decrypt(encrypt, key, vector);
var decryptString = Encoding.UTF8.GetString(decrypt);

DES

var original = "Here is some data to encrypt!";
var key = DesHelper.GenerateKey();
var vector = DesHelper.GenerateVector();
//Default cipher mode is CBC and padding mode is PKCS7.
var encrypt = original.EncryptByDes(key, vector); // Also you can use Helper like this: DesHelper.Decrypt(encrypt, key, vector);
var decrypt = encrypt.DecryptByDes(key, vector); // Also you can use Helper like this: DesHelper.Decrypt(encrypt, key, vector);
var decryptString = Encoding.UTF8.GetString(decrypt);

TripleDES

var original = "Here is some data to encrypt!";
var key = TripleDesHelper.GenerateKey();
var vector = TripleDesHelper.GenerateVector();
//Default cipher mode is CBC and padding mode is PKCS7.
var encrypt = original.EncryptByTripleDes(key, vector); // Also you can use Helper like this: TripleDesHelper.Decrypt(encrypt, key, vector);
var decrypt = encrypt.DecryptByTripleDes(key, vector); // Also you can use Helper like this: TripleDesHelper.Decrypt(encrypt, key, vector);
var decryptString = Encoding.UTF8.GetString(decrypt);

RSA

The default padding is OaepSHA256 and the default encoding is utf8.

var original = "Here is some data to encrypt!";
var (privateKey, publicKey) = RsaHelper.GenerateParameters();
var originalBytes = Encoding.UTF8.GetBytes(original);
var encryptBytes = originalBytes.EncryptByRsa(publicKey); // Also you can use Helper like this: RsaHelper.Encrypt(originalBytes, publicKey);
var decryptBytes = encryptBytes.DecryptByRsa(privateKey); // Also you can use Helper like this: RsaHelper.Decrypt(encryptBytes, privateKey);
var decrypt = Encoding.UTF8.GetString(decryptBytes);
Assert.True(original, decrypt);

ECDSA

The default encoding is utf8.

var original = "Here is some data to encrypt!";
//SignData
var (privateKey, publicKey) = EcdsaHelper.GenerateParameters();
var originalBytes = EcdsaHelper.Encoding.GetBytes(original);
var signBytes = originalBytes.SignDataByEcdsa(privateKey, hashAlgorithm);
//True
var result = originalBytes.VerifyDataByEcdsa(signBytes, publicKey, hashAlgorithm);

//SignHash
var (privateKey, publicKey) = EcdsaHelper.GenerateParameters();
var originalBytes = EcdsaHelper.Encoding.GetBytes(original);
var signBytes = originalBytes.SignHashByEcdsa(privateKey);
//True
var result = originalBytes.VerifyHashByEcdsa(signBytes, publicKey);

DSA

The default encoding is utf8.

var (privateKey, publicKey) = DsaHelper.GenerateParameters();
var originalBytes = DsaHelper.Encoding.GetBytes(original);
var signature = originalBytes.CreateSignatureByDsa(privateKey);
//True
var result = originalBytes.VerifySignatureByDsa(signature, publicKey);
