[ Upstream commit 59ca6c93387d325e96577d8bd4c23c78c1491c11 ] Support rsa & pkcs1pad(rsa,sha1) with priority 150. Test with QEMU built-in backend, it works fine. 1, The self-test framework of crypto layer works fine in guest kernel 2, Test with Linux guest(with asym support), the following script test(note that pkey_XXX is supported only in a newer version of keyutils): - both public key & private key - create/close session - encrypt/decrypt/sign/verify basic driver operation - also test with kernel crypto layer(pkey add/query) All the cases work fine. rm -rf *.der *.pem *.pfx modprobe pkcs8_key_parser # if CONFIG_PKCS8_PRIVATE_KEY_PARSER=m rm -rf /tmp/data dd if=/dev/random of=/tmp/data count=1 bs=226 openssl req -nodes -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -subj "/C=CN/ST=BJ/L=HD/O=qemu/OU=dev/CN=qemu/emailAddress=qemu@qemu.org" openssl pkcs8 -in key.pem -topk8 -nocrypt -outform DER -out key.der openssl x509 -in cert.pem -inform PEM -outform DER -out cert.der PRIV_KEY_ID=`cat key.der | keyctl padd asymmetric test_priv_key @s` echo "priv key id = "$PRIV_KEY_ID PUB_KEY_ID=`cat cert.der | keyctl padd asymmetric test_pub_key @s` echo "pub key id = "$PUB_KEY_ID keyctl pkey_query $PRIV_KEY_ID 0 keyctl pkey_query $PUB_KEY_ID 0 echo "Enc with priv key..." keyctl pkey_encrypt $PRIV_KEY_ID 0 /tmp/data enc=pkcs1 >/tmp/enc.priv echo "Dec with pub key..." keyctl pkey_decrypt $PRIV_KEY_ID 0 /tmp/enc.priv enc=pkcs1 >/tmp/dec cmp /tmp/data /tmp/dec echo "Sign with priv key..." keyctl pkey_sign $PRIV_KEY_ID 0 /tmp/data enc=pkcs1 hash=sha1 > /tmp/sig echo "Verify with pub key..." keyctl pkey_verify $PRIV_KEY_ID 0 /tmp/data /tmp/sig enc=pkcs1 hash=sha1 echo "Enc with pub key..." keyctl pkey_encrypt $PUB_KEY_ID 0 /tmp/data enc=pkcs1 >/tmp/enc.pub echo "Dec with priv key..." keyctl pkey_decrypt $PRIV_KEY_ID 0 /tmp/enc.pub enc=pkcs1 >/tmp/dec cmp /tmp/data /tmp/dec echo "Verify with pub key..." keyctl pkey_verify $PUB_KEY_ID 0 /tmp/data /tmp/sig enc=pkcs1 hash=sha1 [1 compiling warning during development] Reported-by: kernel test robot <lkp@intel.com> Co-developed-by: lei he <helei.sig11@bytedance.com> Signed-off-by: lei he <helei.sig11@bytedance.com> Signed-off-by: zhenwei pi <pizhenwei@bytedance.com> Link: https://lore.kernel.org/r/20220302033917.1295334-4-pizhenwei@bytedance.com Reviewed-by: Gonglei <arei.gonglei@huawei.com> Signed-off-by: Nathan Chancellor <nathan@kernel.org> #Kconfig tweaks Link: https://lore.kernel.org/r/20220308205309.2192502-1-nathan@kernel.org Signed-off-by: Michael S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
