Description Enrico Scholz 2004-05-19 16:09:06 EDT
Description of problem:

is signed correctly, but 'tgpg' fails because of a malformed CRC.

| # wget http://www.fedora.us/FEDORA-GPG-KEY
| # rpm --import FEDORA-GPG-KEY
| # gpg --import FEDORA-GPG-KEY
| # wget http://download.fedora.us/fedora/fedora/2/i386/RPMS.stable/lzo-1.08-0.fdr.2.2.i386.rpm

| # /usr/lib/rpm/tgpg lzo-1.08-0.fdr.2.2.i386.rpm 
| ...
| gpg: malformed CRC

I know some other rpms also:

Btw, it would be nice when 'tgpg' could be used in scripts. E.g. be
more quietly and return a meaningful return code.

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 2 Miloslav Trmač 2005-04-26 16:06:46 EDT
gnupg-1.4.1-1 handles the rpm armored output correctly,
but that looks like the two bugs cancelling each other.

The RPM output doesn't seem to be a valid ASCII armor,
beecrypt's fault.

Created attachment 113689 [details]
Don't return "" for binary data starting with NUL

The attached patch (I'll send it upstream shortly) fixes b64encode().
The check for "" is invalid for binary data.  For NUL-terminated
data it is superfluous, the function does the right thing for zero-length
data anyway.

Paul, if you want me to build an updated package, just yell.

Mitr - if you could build a beecrypt with this in that'd be great.
