AM5728: AM5728 crypto accelerators

Part Number: AM5728

Hi,

I am trying to check crypto accelerators on TI-AM5728 SDK 6.03 linux referring the link:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Kernel/Kernel_Drivers/Crypto.html

I ran the command 

  • ls -l /dev/hwrng

crw------- 1 root root 10, 183 Sep 8 16:47 /dev/hwrng

  • lsmod

cryptodev 49152 0    entry is present

 

  • openssl speed -evp aes-128-cbc -engine cryptodev

    invalid engine "cryptodev"

Why it is giving error ? Also, speed is around 3 seconds, it clearly means it is not using crypto accelerators for speed testing


Also I am referring to the link
https://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Cryptography

  • openssl verify cert.pem

I am getting error on verifying the cert.pem in step Web generation certificate

C = AB, ST = C, L = D, O = E, OU = F, CN = G, emailAddress = H@i.com
error 18 at 0 depth lookup: self signed certificate
error cert.pem: verification failed

    For openssl-1.0.2 and earlier, the engine was called cryptodev. It was renamed to devcrypto in openssl 1.1.0+.

    If you run the command openssl engine -t -c, what output do you see?

    Hey Daniel,

    On running command :         openssl engine -t -c

    Output received:
