AMD public keys (VHDL and Verilog) can be found inside the Vivado Design Suite installation hierarchy at the following location:
<Install_Dir>/Vivado/<version>/data/pubkey/Active Keys
The /pubkey folder holds active keys for both Verilog and VHDL. The
active keys are the latest keys supported by Vivado release. We recommend that users
always use latest keys wherever it is possible.
Deprecated Keys
The /pubkey folder also holds deprecated keys for Verilog and VHDL
both. The deprecated keys are the active keys from the past releases that have been
deprecated to allow new active keys in the latest release of Vivado software. New
public keys are rolled out once a year with one of the major Vivado release and
older keys at that point turn into deprecated key. The deprecated keys are still
supported by Vivado release. We recommend that users always use latest keys wherever
it is possible.
Discontinued Keys
These are the keys for which the support has been removed from Vivado software. These
keys are not stored inside the /pubkey folder. In accordance with
Vivado Software public key policy, public keys older than 5 years will be
discontinued.
We recommend that users encrypt using the latest keys if they have any discontinued keys in the distribution.
