You have not provided sufficient information for anybody to be able to help you. For example, do you know what encryption method was used to encrypt the file? Do you know what type of plaintext is in the file? ASCII, binary or what?

Usually, for decryption, you need a key, a password or alike. If you don't, chances are low.

Your example does not show encrypted, but encoded data. In this case it is base64. Use commands like

Code:
openssl base64 -d <input >output

The openssl command is a little picky about the line length. You have to reformat the text, so that all but the last line are exactly 64 characters long.

I am not getting any data in the output file,its creating empty output file. Please help.

As I said, openssl is a little picky, every encoded line (except the last one) has to be 64 characters long.
