gpg decryption without file

Question

i use gpg crypt but i want to crypt/decrypt files with pipe the content of the .gpg file or as input > filename

per default following syntax gpg --output doc --decrypt doc.gpg

the file doc.gpg must be exists ,decrypted file is doc after decrypt.

i want to decrypt only the doc.gpg content (with cat or pipe) without given a filename,but there are no options available.

next i want to crypt like so

gpg --crypt "this text is secure" --output doc.gpg

is there any option to crypt and decrypt without source input as file ?

Answer 1

The base64 decode (or encode) process must be preceded.

decrypt example:

$ cat encrypted.txt | base64 --decode | gpg --decrypt
gpg: encrypted with 2048-bit RSA key, ID 9000000000000008, created 2019-03-07
      "username <me@example.com>"
Nxxxxxxxxxxxxxxxxxx9

Refer the encrypted.txt file below.

$ cat encrypted.txt
