GpgTar: S/MIME decryption fails with input/output error
Open, NormalPublic
Actions

Description

When decrypting a .p7m file which contains a deep folder structure you get the following error.
(Decrypting the .gpg file for the same folder runs without issues.)

Only the text:

unicode.tar.gz.p7m → Eingabe von C:/Program Files (x86)/GnuPG VS-Desktop/GnuPG//bin/gpgtar.exe --utf8-strings --cms --skip-crypto ...: 
Entschlüsseln fehlgeschlagen: Input/output error.
Eingabefehler: Fehler während der Ausführung von C:/Program Files (x86)/GnuPG VS-Desktop/GnuPG//bin/gpgtar.exe: gpgtar: note: ignoring option --set-filename gpgtar: error creating directory 'unicode_1_/unicode/abcdefghijklmnopqrstuvwxyz 123 öäöß/😁🤞😎❓⁉ abcdefghijklmnopqrstuvwxyz Ä/😎❓⁉ abcdefghijklmnopqrstuvwxyz 1/😎❓⁉ abcdefghijklmnopqrstuvwxyz 2/😎❓⁉ abcdefghijklmnopqrstuvwxyz 3': No such file or directory

On the commandline the following will work:

C:\Users\g10code.WIN-TEST3\Documents>gpgsm -d unicode.tar.gz.p7m > unicode.tar.gz

C:\Users\g10code.WIN-TEST3\Documents>gpgtar -dv --skip-crypto unicode.tar.gz

This was already present in 3.1.26, where the error message was missing the output from gpgtar. So there was an improvement

Lets make sure that we look into this for 3.3

For S/MIME archives we still use the old code. gpgtar doesn't even support gpgsm.

What happens if you call gpgtar with --utf8-strings --cms additionally to the other options? And what happens if you pipe the archive to gpgtar's stdin?

In any case, this looks like a problem in gpgtar unless it's related to wrong command line options.

Nobody uses gpgtar for S/MIME
