Decrypt using winscp

Hi Team,
Is it possible to download files from linux server to windows via winscp, with condition like files will be encrypted but while downloading/copying from linux to windows it should be decrypted by winscp. Is there any plugin available which we can use to achieve this.

Encrypted how? WinSCP cannot decrypt file encrypted with an arbitrary encryption your server happens to use.

WinSCP though supports encrypting files at rest, on an SFTP server:
