SecureBlackbox 16: When I encrypt the data with a public key, the decryptor asks for the private key twice. Where does the second key come from?

Note: This article applies only to SecureBlackbox Legacy. For future development please consider using the latest version.

Most likely, the key used for encryption has a subkey and the encryption is done for both the key and subkey.

To disable the subkey (i.e., to exclude it from the encryption process), set its Enabled property to false.
