The encryption provider documentation will be updated in v4 since the system has changed and is now much easier to setup.
The interface is simplier, it just takes a byte[] input and needs to return the encrypted/decrypted data as a byte[]:

public interface IEncryptionProvider
{
    byte[] Encrypt(byte[] input);
    byte[] Decrypt(byte[] input);
}

Please wait a little bit for v4 release, I should release it at the same time as .NET 7 release.
