1. You need to generate a PGP key pair (public and private). You can use tools like GPG or any online PGP generator. Public key : Share this with anyone who wants to send data securely to your API. Private key : Keep this on your server to decrypt incoming data. 2. Install a PGP Library To handle PGP encryption in ASP.NET, you can use libraries like BouncyCastle . 3. Client Encrypts Data The client will encrypt their data using your public key and send it to your API. 4. Decrypt Data in your API In your API, you'll need to decrypt the data using your private key . Here's an example in C# using the BouncyCastle library: public string DecryptData(Stream encryptedData, string privateKey, string passPhrase) { // Decrypt the data using your private key // (You'll need a helper function here to handle the PGP decryption) } After decrypting the data, you can verify if it’s from a trusted client by checking their signature, or by using other authentication methods (like tokens). Hope this helps!
