Subject: [PATCH v7 0/5] KEYS: asymmetric: tpm2_key_{rsa,ecdsa}

Testing
=======

RSA
---

tpm2_createprimary --hierarchy o -G rsa2048 -c owner.txt
tpm2_evictcontrol -c owner.txt 0x81000001
tpm2_getcap handles-persistent
openssl genrsa -out private.pem 2048

keyctl pkey_sign $serial 0 plaintext.txt enc=pkcs1 hash=sha256 > signed.dat
keyctl pkey_verify $serial 0 plaintext.txt signed.dat enc=pkcs1 hash=sha256

ECDSA
-----

tpm2_createprimary --hierarchy o -G ecc -c owner.txt
tpm2_evictcontrol -c owner.txt 0x81000001
openssl ecparam -name prime256v1 -genkey -noout -out private.pem
tpm2_import -C 0x81000001 -G ecc -i private.pem -u key.pub -r key.priv
tpm2_encodeobject -C 0x81000001 -u key.pub -r key.priv -o key.priv.pem
openssl asn1parse -inform pem -in key.priv.pem -noout -out key.priv.der
serial=`cat key.priv.der | keyctl padd asymmetric tpm @u`
echo "abcdefg" > plaintext.txt
keyctl pkey_sign $serial 0 plaintext.txt hash=sha256 > signed.dat
keyctl pkey_verify $serial 0 plaintext.txt signed.dat hash=sha256

Closed Issues
=============

* When verifying ECDSA signature, _ecdsa_verify() returns -EKEYREJECTED.
  * v7: rewrote the signature encoder with a more structured layout.
