Key for Blob Encapsulation on LS1046ARDB

[Faizanbaig]

Hi,

I am performing Blob Encapsulation on LS1046ARDB using the key generated by Random Number Generator.
I want to know whether I can bypass the Randomly Generated Key and use my own key for encapsulation? I mean a custom key.
If yes , please let me know how..

Thanks,
Faizan

Please refer to the following update from the AE team.

Please ask customer share these information,
1. Which SDK customer is using? LSDK21.08?
2. Customer did Blob Encapsulation in which software component? u-boot? Linux?
3. Can customer share their running log about Blob Encapsulation?

In LSDK21.08 Linux, there is one userspace tool "caam-keygen", which supports create either from a defined plain key or randomly.
Customer can refer to this document section "10.5.3.2 DM-Crypt with CAAM’s tagged key".
