Name        : opencryptoki
Product     : Fedora 34

Summary     : Implementation of the PKCS#11 (Cryptoki) specification v2.11
Description :
Opencryptoki implements the PKCS#11 specification v2.11 for a set of
cryptographic hardware, such as IBM 4764 and 4765 crypto cards, and the
Trusted Platform Module (TPM) chip. Opencryptoki also brings a software
token implementation that can be used without any cryptographic
This package contains the Slot Daemon (pkcsslotd) and general utilities.

Update Information:

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.  The problem is fixed in opencryptoki-3.16.0-2
