(Xojo Plugin) Generate a Random 256-bit AES Key and RSA EncryptSee more RSA ExamplesGenerates a random 256-bit AES key and encrypts using an RSA public key. Only the owner of the RSA private key will be able to decrypt the AES key.
// The RSA public key is used for encryption, and the private key for decryption. // The public key's role is to make encryption accessible to anyone while ensuring that // only the private key holder can decrypt the messages. // The public key is designed to be widely distributed so anyone can use it to encrypt messages // intended for the owner of the private key. // Load our 2048-bit RSA public key. Dim pubKey As New Chilkat.PublicKey // In all Chilkat methods expecting a path, you pass either absolute or relative paths. Dim success As Boolean success = pubKey.LoadFromFile("rsaKeys/Test2048Rsa.pem") If (success = False) Then System.DebugLog(pubKey.LastErrorText) Return End If Dim rsa As New Chilkat.Rsa // Tell RSA to use the public key. success = rsa.ImportPublicKeyObj(pubKey) // Generate a random 256-bit AES key (32 bytes) Dim bdAesKey As New Chilkat.BinData Dim prng As New Chilkat.Prng success = prng.GenRandomBd(32,bdAesKey) // RSA encrypt. success = rsa.EncryptBd(bdAesKey,False) // Save the RSA encrypted AES key to a file. success = bdAesKey.WriteFile("rsaEncrypted/myAes.key") |
