Folks,
Recently was helping Henry Story with his foaf+ssl* code (folks on
this list may well be interested; and ran into something I've been
totally relying on for years - but never knew that was happening:
'ca' (but not x509 or req) are clever enough to magically output as
DER when SPKAC is used and an output file is specified (but will
otherwise default to PEM; both on stdout and in the -outdir.
E.g. (from app.c):
if (spkac_file != NULL)
{
j=certify_spkac(x,spkac_file,pkey,x509,dgst,attribs,db,
if (outfile)
{
output_der = 1;
batch = 1;
}
}
which means that
openssl ca -config /etc/CA/openssl.conf -days 180 -notext -batch -
spkac ~/tmp/eg.spkac foo
and
openssl ca -config /etc/CA/openssl.conf -days 180 -notext -batch -
spkac ~/tmp/eg.spkac -out foo
do yield a PEM resp. DER format in 'foo'. ANd that is a bit confusing.
I suggest below for the docs - as it had me scratching my head for a
bit. And I am not that unfamiliar with openssl :)
Cheers,
Dw.

If you need to include the same component twice then it can be
preceded by a number and a '.'.
+ Note that when handling SPKAC files the output format is set
+ to DER, not PEM when the output is written to a file specified
+ with -out. As to allow sending it straight to a browser with a
+ MIME-type of 'application/x-x509-user-cert'.

+ However the format is kept PEM when sent to stdout (i.e. without the
+ -out flag) or when written to a '-outdir'.
