caam-keygen source code for iMX8

[nxpuser_rb]

Does anyone have an active link to the source code for the caam-keygen source code?  I have a version of yocto embedded linux from Toradex that I built for the Apalis iMX8QM module.  It runs successfully on the Toradex dev kit for the IXORA carrier board with the Apalis iMX8.  I can load manually the linux modules required for dm-crypt, dm-mod, and trusted.  The command "dmsetup targets" lists crypt. I can successfully follow the instructions in the i.MX Linux User's guide to encrypt/decrypt data on non-volatile storage using a CAAM trusted plain key, but the bsp does not include the utility caam-keygen utility required for encryption using CAAM tagged keys.

Can someone give the source for the caam-keygen utility?  I have the arm cross compiler for the bsp, so I could build the utility separately and install it on the board.

Thanks

Hi @nxpuser_rb 

You can find the source from the link: GitHub - nxp-imx/keyctl_caam: Keyctl CAAM Security

Hi Harvey,

Thank you for giving me the link for caam-keygen utility!  I was able to download the files and to build the utility successfully for the Toradex Apalis-iMX8 dev kit that I've been using.  After I transferred the utility to the embedded linux running on the dev kit, I was able to execute the steps successfully in the app note for encrypting and decrypting data with DM-Crypt and CAAM.  The app note I've been using is AN12714,
i.MX Encrypted Storage Using CAAM Secure Keys Rev 2.

Thanks Again!!
