body->nested.part instead of b->nested.part in the
do_detached_signature_verify function, and save its body and mime
headers in create_local_cache. Now all signed messages should
verify correctly.
* Protect against potential crash bug in write_passfile function by
checking if text != NULL. text can only be null if there are no
passwords to save. We assume we could get write_passfile called
with null arguments, so this is just to protect that.
* Add handling of corner cases to several functions by initializing some
variables. Reported and patched by James Jerkins.
* When selecting the certificate/key pair to encrypt/decrypt the password
file choose it in this order:
- if -pwdcertdir is given look for certificates there, if nothing
there, we bail out;
- otherwise we look in the default directory, if anything there
and it matches to be a key/cert pair, we use it;
- otherwise we check if smime_init() has been called. If not
we call it;
- we check if a key/cert pair has been found with smime initialized,
if so, use it and copy it to the default directory;
- if not, check if there is anything in the default smime directories
(.alpine-smime/private and .alpine-smime/public), and in this
case copy it to the default.
- otherwise we bail. We will eventually create a certificate/key
pair for the user;
- finally, if we called smime_init(), we call smime_deinit().
Throughout this process, if smime_init() was not called before
we tried to get the cert/key pair we exit this process without
ps_global->smime->inited set, so that other process that need
to call smime_init() get the right structure initialized. This is
done because we might pick a cert/key pair to decrypt the password
file.
