Feature request: PGP verification for email signatures

andi448 opened this issue · comments

Is your feature request related to a problem? Please describe.
Wanted to verify some PGP mail signatures, but couldn't get it working.
I just exported the mail from Thunderbird and copy pasted the content into the input field, but then it either says: Couldn't verify message: Error: Cannot verify detached signature without data input or if I manually trim it down to the OpenPGP section and add -----BEGIN PGP SIGNED MESSAGE-----, it tells me Couldn't verify message: Error: Sig verify error: missing ASN header for MD5.

Describe the solution you'd like
Would be nice if one could copy paste a PGP signed mail directly into the input field without converting or something.

Describe alternatives you've considered
I have tried to verify the signature with Kleopatra and Gpg4win CLI, but also without success. Seems like I am missing something here.
