Hi, This patch set adds the AF_ALG user space API to externalize the asymmetric cipher API recently added to the kernel crypto API. The patch set is tested with the user space library of libkcapi [1]. Use [1] test/test.sh for a full test run. The test covers the following scenarios: * sendmsg of one IOVEC * sendmsg of 16 IOVECs with non-linear buffer * vmsplice of one IOVEC * vmsplice of 15 IOVECs with non-linear buffer * invoking multiple separate cipher operations with one open cipher handle * encryption with private key (using vector from testmgr.h) * encryption with public key (using vector from testmgr.h) * decryption with private key (using vector from testmgr.h) Note, to enable the test, edit line [2] from "4 99" to "4 13".
