Hello! I have an encrypted paper wallet, I know the pass phrase, no worries however I wonder if I can import an encrypted wallet to electrum. Is it better to import or sweep? As soon as I decrypt it I am gonna send the funds to other addresses. Are there any guides to follow?

Hi,
So I have a paper wallet with an encrypted private key with 54 entries starting with for example rgHM7 or wTdev, so it doesn't seem to be a bip38 encryption. What kind of encryption can it be and how can I go about to decrypt it. The paper wallet was generated at bitaddress.org. And oh how I regret encrypting it
Could someone please help?
