GnuPG Encryption without special characters

I am using the below code to encrypt the text file. I need to read the encrypted text back and need to send in email. But for this its needs to be encoded without any special characters.

But When I encrypt using the below code, it is encrypting with special chracters.

gpg --output test.txt.gpg --encrypt --recipient test@test.com test.txt

Any Ideas?

Solution

You need to add the "-a" (ASCII armor) argument to gpg:

gpg -a --output test.txt.gpg --encrypt --recipient test@test.com test.txt

This tells gpg to format it's output in base 64 encoding.
