xySecurity

Extracted component of xyToolz — source is maintained in the main xyToolz repository; this package exposes only this module standalone.

Password hashing, RSA/JWT, and data-protection helpers for .NET.

Install

dotnet add package xySecurity

Contents

  • xyHasher — PBKDF2-based password hashing:

    • HashPbkdf2(string), VerifyPbkdf2(string, string)
    • BuildSaltedHash(HashAlgorithmName, string, out byte[] salt), VerifyPassword(...) overloads
    • BuildKeyFromPassword, HashToBytes, HashToString, GenerateSalt(int)
  • xyRsa — RS256 JWT signing/validation:

    • LoadKeysAsync(publicKeyPem, privateKeyPem), ConfigureAsync(issuer, audience)
    • GenerateJwtAsync(IDictionary<string,object> claims, TimeSpan validFor)
    • ValidateJwtAsync(string token, bool validateLifetime = true)
    • GetPublicKeyAsPemAsync(), Encrypt(byte[], RSA), Decrypt(byte[], RSA)
  • xyDataProtector — encrypt/decrypt objects, strings, bytes, and files:

    • ProtectAsync<T> / UnprotectAsync<T>, ProtectString / UnprotectStringAsync, ProtectBytes / UnprotectBytesAsync
    • SaveProtectedToFileAsync<T> / LoadProtectedFromFileAsync<T>, ProtectFileAsync<T>
    • OverrideForTests / ResetOverride — swap in an IxyDataProtector test double.
  • IxyDataProtector — interface for mocking xyDataProtector in unit tests.

Example

string hash = xyHasher.BuildSaltedHash(HashAlgorithmName.SHA256, "Secure123!", out var salt);
bool valid = xyHasher.VerifyPassword(HashAlgorithmName.SHA256, "Secure123!", hash);

byte[] protectedBytes = await xyDataProtector.ProtectString("secret");
string plain = await xyDataProtector.UnprotectStringAsync(protectedBytes);

Dependencies

  • Microsoft.IdentityModel.Tokens
  • System.IdentityModel.Tokens.Jwt
  • System.Security.Cryptography.ProtectedData
  • xyLogger
  • xyExtensions, xyQOL, xyFilesystem, xySerialization (project references)
