From 02cf1357dd5ee34a57371f55b9d312b8b9e3a7e8 Mon Sep 17 00:00:00 2001 From: Justus Winter Date: Thu, 7 Apr 2016 13:55:42 +0200 Subject: [PATCH] g10: Fix exporting secret keys of certain sizes. * g10/build-packet.c (do_key): Do not use the header length specified by the public key packet from the keyring, but let 'write_header2' compute the required length. -- Specifically exporting RSA keys of length 1024 failed, as the encoded public key packet requires 141 bytes a length that fits into one byte, but the secret key is significantly larger, making the export fail.
