Hi, We are planning to create keys and encrypt/decrypt the files from u-boot using TPM. Could you please point us to references for include the crypto APIs? or where need to start with?

Your help is much appreciated.

Thanks, saravanan

Sorry, I do not have the time to support such questions.

All I can say is that here you can find the TPM commands supported by the U-Boot shell. I'm not familiar with if/how U-Boot supports any form of file/fs encryption.
