Hi, NXP


I am developing an application that runs on an imx6ul based industrial embedded computer. Linux has been built with using yocto.

Is it securely to print out to console all keys by CAAM on boot up?

 

...

platform caam_sm: blkkey_ex: 8 keystore units available
platform caam_sm: 64-bit clear key:
platform caam_sm: [0000] 00 01 02 03 04 0f 06 07
platform caam_sm: 64-bit black key:
platform caam_sm: [0000] 3c a8 41 75 ce eb eb 36
platform caam_sm: [0008] 0f e5 59 ba 35 ef 33 3a
platform caam_sm: 128-bit clear key:
platform caam_sm: [0000] 00 01 02 03 04 0f 06 07
platform caam_sm: [0008] 08 09 0a 0b 0c 0d 0e 0f
platform caam_sm: 128-bit black key:
platform caam_sm: [0000] 35 a4 be 55 7b e7 fd 21
platform caam_sm: [0008] 2b ca 03 b8 f7 95 05 1e
platform caam_sm: 192-bit clear key:
platform caam_sm: [0000] 00 01 02 03 04 0f 06 07
platform caam_sm: [0008] 08 09 0a 0b 0c 0d 0e 0f
platform caam_sm: [0016] 10 11 12 13 14 15 16 17

... and so on

 

If not, how can I turn out this?
