Provides simple cryptographic related classes for hashing/verifying data, encrypting/decrypting data and creating crypto random data in .NET.


ByteDev.Crypto has been written as a .NET Standard 2.0 library, so you can consume it from a .NET Core or .NET Framework 4.6.1 (or greater) application.

ByteDev.Crypto is hosted as a package on To install from the Package Manager Console in Visual Studio run:

Install-Package ByteDev.Crypto

Further details can be found on the nuget page.

Release Notes

Releases follow semantic versioning.

Full details of the release notes can be viewed on GitHub.


The library is broken into three main namespaces:

  • Hashing
  • Encryption
  • Random


Use namespace ByteDev.Crypto.Hashing.

This namespace contains two main classes: HashService and FileChecksumService.


HashService class methods:

  • Hash
  • Verify
IHashService service = new HashService(new Md5Algorithm(), EncodingType.Base64);

// Hash a phrase
string base64Hash = service.Hash(new ClearPhrase("Password1"));

// Verify a phrase against a hash
bool isSuccessful = service.Verify(new ClearPhrase("Pasword123456"), base64Hash);

FileChecksumService class methods:

  • Calculate
  • Verify
  • Matches
IFileChecksumService service = new FileChecksumService(new Md5Algorithm(), EncodingType.Hex);

// Calculate file checksum (hash)
string hexChecksum = service.Calculate(@"C:\myFile.txt");

// Verify existing checksum matches file's
bool isSuccessful = service.Verify(@"C:\myFile.txt", hexChecksum);

// Search directory for files with a particular checksum
IList<string> matches = service.Matches(@"C:\Temp", hexChecksum); 


Use namespace ByteDev.Crypto.Encryption.

EncryptionService class methods:

  • Encrypt
  • Decrypt
  • EncryptProperties
  • DecryptProperties

Initializing EncryptionService:

IEncryptionAlgorithm algo = new RijndaelAlgorithm();

IEncryptionKeyIvFactory keyFactory = new EncryptionKeyIvFactory(algo);
EncryptionKeyIv keyIv = keyFactory.Create("Password1", Encoding.UTF8.GetBytes("someSalt"));

IEncryptionService service = new EncryptionService(algo, keyIv);
Encrypt & Decrypt

Encrypt a secret with a key and then decrypt it:

byte[] cipher = service.Encrypt("mySecret");

string clearText = service.Decrypt(cipher);	 

// clearText == "mySecret"

Once a byte array cipher has been created the ByteDev.Encoding.Encoder class can be used for any required encoding:

byte[] cipher = service.Encrypt("mySecret", keyIv);

Encoder encoder = new Encoder(EncodingType.Hex);

string hex = encoder.Encode(cipher);
EncryptProperties & DecryptProperties

The EncryptionService class also supports encrypting/decrypting an object's public string properties that use EncryptAttribute through the EncryptProperties and DecryptProperties methods.

public class MyInfo
    public string Secrets { get; set; }

var info = new MyInfo { Secrets = "Some secrets" };

service.EncryptProperties(info, EncodingType.Hex);

// info.Secrets is now encrypted and encoded as hex

service.DecryptProperties(info, EncodingType.Hex);

// info.Secrets == "Some secrets"


Use namespace ByteDev.Crypto.Random.

CryptoRandomString class methods:

  • GenerateString
  • GenerateArray

Generate a random string of a specified length using only the character set specified (you can also call GenerateString with a min and max length):

const int length = 5;

using (var r = new CryptoRandomString(CharacterSets.AlphaNumeric))
    string randomString = r.GenerateString(length);

Generate a char array of random characters of a specified length using only the character set specified (you can also call GenerateArray with a min and max length):

const int length = 10;

using (var r = new CryptoRandomString(CharacterSets.Digits))
    char[] randomChars = r.GenerateArray(length);

CryptoRandomNumber class methods:

  • GenerateInt32

Generate a random number.

using (var r = new CryptoRandomNumber())
    int randomInt = r.GenerateInt32();
