You are right - the command line was wrong. Here’s the correct line, which
should work, but doesn’t:

$ openssl cms -engine pkcs11 -aes256 -encrypt -in data.txt -binary
-outform PEM -out data.txt.enc
"pkcs11:object=Certificate%20for%20Key%20Management;object-type=cert"
engine "pkcs11" set.
Error opening recipient certificate file
pkcs11:object=Certificate%20for%20Key%20Management;object-type=cert
140735201178448:error:02001002:system library:fopen:No such file or
directory:bss_file.c:398:fopen('pkcs11:object=Certificate%20for%20Key%20Man
agement;object-type=cert','r')
140735201178448:error:20074002:BIO routines:FILE_CTRL:system
lib:bss_file.c:400:
unable to load certificate
$ openssl cms -engine pkcs11 -aes256 -encrypt -in data.txt -binary
-outform PEM -out data.txt.enc token.cert.pem
engine "pkcs11" set.
$




And yes, it’s about time for OpenSSL to incorporate proper support for
PKCS#11.
