MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old
The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file since that allows the target X.509 certificate to be specified by subjectKeyId rather than by issuer + serialNumber. However, older versions of the OpenSSL crypto library (such as may be found in CentOS 5.11) don't support CMS. Assume everything prior to OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case. Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so give an error from the sign-file script if the caller requests anything other than SHA1. The compiler gives the following error with an OpenSSL crypto library that's too old: HOSTCC scripts/sign-file scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory #include <openssl/cms.h> Reported-by: Vinson Lee <vlee@twopensource.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: David Woodhouse <David.Woodhouse@intel.com>
