1. Quick Start

1.1. Install Package

PM> Install-Package Aoxe.Cryptography

1.2. MD5

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

1.3. SHA

var apple = "apple";
//D0BE2DC421BE4FCD0172E5AFCEEA3970E2F3D940
var sha1String = apple.ToSha1String();
var sha1Bytes = apple.ToSha1();
//3A7BD3E2360A3D29EEA436FCFB7E44C735D117C42D1C1835420B6B9942DD4F1B
var sha256String = apple.ToSha256String();
var sha256Bytes = apple.ToSha256();
//3D8786FCB588C93348756C6429717DC6C374A14F7029362281A3B21DC10250DDF0D0578052749822EB08BC0DC1E68B0F
var sha384String = apple.ToSha384String();
var sha384Bytes = apple.ToSha384();
//844D8779103B94C18F4AA4CC0C3B4474058580A991FBA85D3CA698A0BC9E52C5940FEB7A65A3A290E17E6B23EE943ECC4F73E7490327245B4FE5D5EFB590FEB2
var sha512String = apple.ToSha512String();
var sha512Bytes = apple.ToSha512();

1.4. 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);

1.5. 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);

1.6. 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);

1.7. 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);

1.8. 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);

1.9. 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);

1.10. 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);
