Issue with encrypt functions without adding mormot.crypt.rsa to uses!

I found a problem and it took me a whole day. When using the encryption functions. The mormot.crypt.rsa unit must be used.
Otherwise, the output of some functions is nil and causes problems. For example:
CryptCipher := Decrypt('aes-256-gcm', Pointer(Lkey));

Seems, in the intialziation section of the mormot.crypt.rsa unit, some classes are created and initialized.

I can not reproduce it here with the 'aes-256-gcm' algorithm.

Please try to debug a little bit more and report here the exact problem.

I have identified the location of the error in the source below.

https://gist.github.com/a-nouri/cb11785 … c11425d05c

And I call it :

procedure TForm1.Button1Click(Sender: TObject);
var
  MyCryptAndHash: TMyCryptAndHash;
  Enc: string;
begin
  MyCryptAndHash := TMyCryptAndHash.Create;
  Enc := MyCryptAndHash.AESEncrypt('111', '01234567890123456789012345678912');
  MyCryptAndHash.Free;
end;

After adding mormot.crypt.rsa to the uses section, the problem is solved.

In mormot.crypt.secure function Cipher return nil. Function can't resolve algoname because it is not initilized
