Bug ID: 357462
Summary: Decryption failure when message has no version header
Product: kgpg
Version: 2.14.0
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: minor
Priority: NOR
Component: general
Assignee: k...@opensource.sf-tec.de
Reporter: mynameisricha...@gmail.com
I was trying to decrypt a message which had no GPG version header in it. I
would get a "Decryption failed" notice. When clicking on the "Details" button,
it would show the program's steps of decrypting, but would also display the
message in there. So I figured it was weird that it says failure, but has the
message decrypted correctly anyway. I have since did more testing with this
bug, and found an easy workaround. All that was missing was a blank line before
the cipher-text. Problem was the sender of said message uses a different GPG
frontend that when using the --no-version option, doesn't include that blank
line.
Reproducible: Always
Steps to Reproduce:
1. Be sent an encrypted message without the version header (and no blank
line/whitespace between the begin PGP message header and ciphertext.)
2. Decrypt message
3. Check for more details, find message in there.
Actual Results:
I was able to read my message within the detailed program logs of the
decryption failure notice.
Expected Results:
Ideally, it should have been able to detect whether or not there's a
whitespace/version header or otherwise isolate on the cipher-text, and decrypt
text accordingly without causing a false failure.
Of course the simple fix is to add in a whitespace yourself between begin pgp
message header and cipher-text.
