Remote File integrity

Hi all,

I have been checking the file integrity(calculating SHA1 cheksum) of tar files in linux server in my java code by using linux sha1sum.

Now i have to implement the same for tar files stored in remote SFTP servers (eg freeFTPd or linux native) without copying them to this server or streaming them to stdin.
I can do it after copying or by streaming to stdin of this server.but any method in which i can remotely do it?
any pointers?

There's no way to do this remotely that I can think of .

If you have sftp access, then you probably have ssh access. Connect with ssh, and run the "sum" command (or any other command of your choosing) on the file.
