DrUalcman-Cipher 1.3.10

DrUalcman-Cipher

A .NET library for encryption, decryption, and token generation with support for Base64, MD5 hashing, and JWT tokens.

Features

Secret Class

• Encrypt and decrypt text using a custom algorithm with secret keys
• Supports both synchronous and asynchronous operations
• Generate and verify hash keys using MD5
• Multiple constructors for different initialization scenarios

JWT Class

• Create and verify JSON Web Tokens (JWT)
• Support for custom claims, issuer, audience, and roles
• Token expiration configuration
• Both standard HS256 and custom DRCKJ algorithms
• Synchronous and asynchronous methodsHash Utilities

MD5 hash computation

• Base64 encoding/decoding (standard and URL-safe variants)
• Hexagesimal conversions

Instalation

Install nuget

dotnet add package DrUalcman-Cipher

Usage

Secret Class Examples

// Initialize with default secret and key
var secret = new Secret();

// Initialize with custom secret and key
var secret = new Secret("mysecret", 123);

// Encrypt text
string encrypted = secret.Encrypt("Hello World");

// Decrypt text
string decrypted = secret.Decrypt(encrypted);

// Generate hash key
string hash = secret.GetHashKey();

// Verify hash key
bool isValid = secret.VerifyHashKey(hash);

JWT Class Examples

// Create a basic token with default expiration (7 days)
string token = JWT.CreateToken();

// Create token with custom claims
var claims = new Dictionary<string, object>
{
    { "userId", 123 },
    { "username", "john.doe" }
};
string token = JWT.CreateToken(claims);
// Verify token signature
bool isValid = JWT.VerifySignature(token);

// Create token with custom key
string token = JWT.CreateToken(claims, "mysecretkey");

// Verify token signature
bool isValid = JWT.VerifySignature(token, "mysecretkey");

// Get payload from token
if (JWT.TryGetPayloadToken(token, out var payload))
{
    // Use payload data
}

Hash Utilities Examples

// MD5 Hash
MD5 md5 = new MD5();
string hash = md5.ComputeHash("text to hash");

// Base64 Encoding
string encoded = Base64.Base64Encode("text to encode");
string decoded = Base64.Base64Decode(encoded);

// URL-safe Base64
string urlEncoded = Base64.Base64UrlEncode("text to encode");
string urlDecoded = Base64.Base64UrlDecode(urlEncoded);
