I'm a bit unsure about the format of the key here. Is it different
from the normal one used by U-Boot?
The format used by pkey is the der format without the first 24 bytes.
For example, to create this key in a shell, I use the following commands :
openssl rsa -in private.pem -pubout -outform der -out public.der
dd if=public.der of=public.raw bs=24 skip=1
As described in the comment line 340 in the file test/lib/asn1.c.
Regards,
Simon
