PKCS#7: Provide a key type for testing PKCS#7
Provide a key type for testing the PKCS#7 parser. It is given a non-detached
PKCS#7 message as payload:
keyctl padd pkcs7_test a @s <stuff.pkcs7
The PKCS#7 wrapper is validated against the trusted certificates available and
then stripped off. If successful, the key can be read, which will give the
data content of the PKCS#7 message.
A suitable message can be created by running make on the attached Makefile.
This will produce a file called stuff.pkcs7 for test loading. The key3.x509
file should be put into the kernel source tree before it is built and
converted to DER form:
