The PKCS#12 bundle was created by running the following in an
interactive shell in ../../qsslsocket/certs/:

openssl pkcs12 -export -in leaf.crt \
               -inkey leaf.key -out leaf.p12 \
               -certfile inter.crt -CAfile ca.crt

An empty password was provided (twice).  The pkcs.crt and pkcs.key
files were then copied here and leaf.p12 was moved here.


The test-case with no private key (in a valid PKCS12 file) was created
similarly but with the command adjusted to:

openssl pkcs12 -export -in leaf.crt \
               -nokeys -out leaf-nokey.p12 \
               -certfile inter.crt -CAfile ca.crt

The file leaf-nokey.p12 was then moved here.
