title: gpg decryption without file
body: <p>i use gpg crypt but i want to crypt/decrypt files with pipe the content of the .gpg file or as input > filename</p>
  
  <p>per default following syntax
  gpg --output doc --decrypt doc.gpg</p>
  
  <p>the file doc.gpg must be exists ,decrypted file is doc after decrypt.</p>
  
  <p>i want to decrypt only the doc.gpg content (with cat or pipe) without given a filename,but there are no options available.</p>
  
  <p>next i want to crypt like so </p>
  
  <p>gpg --crypt "this text is secure" --output doc.gpg</p>
  
  <p>is there any option to crypt and decrypt without source input as file ?</p>
