I understand the topic very well. What would prevent an attacker from using the same algorithm as WinSCP to decrypt the password? An encryption without a password (or any other form of a secret key) is not an encryption. It's just an obfuscation.

Hi Martin,

I think you did not understand the topic. There is no password for encryption. We are talking about built in function for WinSCP.exe. Basically WinSCP encrypt a text file using with its own algorithm that only decrypt with WinSCP as well for converting encrypted file to text file line by line while processing.

Thats it. Thanks.
