Encryption

The Encryption class provides mechanisms for RSA encryption/decryption, along with the generation of self-signed certificates.

Properties

• PublicKey: Retrieves the public key for the current RSA provider instance.

Methods

Encrypt

• Purpose: Encrypts a string using the specified public RSA key.
• Parameters:
  • string publicKey: The RSA public key in XML format.
  • string data: The plaintext string to be encrypted.
• Returns: string: The encrypted data in base64 format.
• Usage Example:

var encryptedData = Encryption.Encrypt(publicKey, "Hello World");

Decrypt

• Purpose: Decrypts a base64-encoded string using the private RSA key.
• Parameters:
  • string data: The base64-encoded encrypted data.
• Returns: string: The decrypted plaintext.
• Usage Example:

var decryptedData = Encryption.Decrypt(encryptedData);

GenerateSelfSignedCertificate

• Purpose: Generates a self-signed X509 certificate with RSA encryption.
• Parameters:
  • string subjectName: The subject name for the certificate (common name).
• Returns: (X509Certificate2 certificate, string password): A tuple containing the generated certificate and its password.
• Usage Example:

var (certificate, password) = Encryption.GenerateSelfSignedCertificate("CN=example.com");
