Subject: [PATCH] SOFT: Check the EC Key on C_CreateObject and C_DeriveKey
|
|
|
|
When constructing an OpenSSL EC public or private key from PKCS#11
|
|
attributes or ECDH public data, check that the key is valid, i.e. that
|
|
the point is on the curve.
|
|
|
|
This prevents one from creating an EC key object via C_CreateObject with
|
|
invalid key data. It also prevents C_DeriveKey to derive a secret using
|
|
ECDH with an EC public key (public data) that uses a different curve
|
|
or is invalid by other means.
