Hello everyone,
I've tried to find info regarding this but no real luck so far. It was
discussed in the thread "encryption/decryption without files", but I
haven't found a reply there that covers 'symmetric decryption'.
And yes, I am aware of plaintext, shell, bash, etc.
These are generally short text snippets, which can be considered
internal, not even confidential (I'm not familiar with the names of
levels up to "Ultraviolet Top Secret", but this would barely reach "Just
don't forget too many print outs on the tube" level. :) )
We use it mainly for small txt files stored in the cloud, some things
sent over Google or stored temporarily in some docs at Google Drive, etc.
Anyway, I often use -ac in command line to encrypt these text snippets.
I write the text or message, finish with Ctrl+Z (We use Windows at
work), and copy the encrypted text.
One thing I would like to do is the opposite, however, but I haven't
figured out how to, yet.
If I want to decrypt a short text snippet, I have to
1. copy the snippet
2. paste it into a txt file
3. save the file
4. use "gpg -d file.txt"
(The text is then read in the CL window, I have no interest in this case
to save the decrypted text, just read it and e.g. check a reference)
Is it possible to replace steps 2 and 3 by pasting in the text in the CL?
I've tried "gpg [Enter]", but I always get the message "decryption
failed: bad key" as you can see below.
Everything below the encrypted message happened automatically when I
pasted in the text first time, though next time it did wait for me to
supply the passphrase, with same "bad key" result, however.
Note that the last line "-----END PGP MESSAGE-----" disappears. Also,
the prompt does not return to the standard ">", until I have done a
Ctrl+Z or Ctrl+C.
>gpg

gpg: TWOFISH encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: bad key
As I wrote in the subject line, this is when using symmetric encryption
(as you can see), since we use that in these particular cases.
It does work with asymmetric encryption, though the workflow is a bit
dodgy even there, I think? The END PGP MESSAGE line disappears here as
well and the first failed attempt for the passphrase happened without my
input too.
