problem with importing public keys / aes keys using "softhsm2-util --import"

[catfish-amine]

Hello,
First I wanted to know if there is any doc for the softhsm2-util especially using "import" action. Because I am having a few problems when I'm trying to import a RSA public keys that are - as far as I understood - can't be in PKCS8 format, to resolve that I tried to work around this issue by using the "--aes" option but I don't think that it is the proper way to do it.

On the other hand, when I am trying to use an AES secret key (successfully imported using --aes ) I keep getting this error:
68 ErrorCode corresponding to: KEY_FUNCTION_NOT_PERMITTED
maybe it is coming from the format I am using for my AES key as it also can't be in PKCS8 format and there is no specifications on how it should be handled.

To Import an RSA Public Key, it should be in X.509 SubjectPublicKeyInfo (SPKI) format.
PEM with the -----BEGIN PUBLIC KEY----- header.

This is how I generate my pair of RSA keys:

openssl genpkey -algorithm RSA -out private.pem -pkeyopt rsa_keygen_bits:1024
openssl pkcs8 -topk8 -nocrypt -in private.pem -out private_pkcs8.key
openssl rsa -pubout -in private_pkcs8.key -out public.pem

and then I try to import them like this :

softhsm2-util --import private_pkcs8.key --token "TEST" --label "TEST_PRIV" --id A001 --force
=> The key pair has been imported.

softhsm2-util --import public.pem --token "TEST" --label "TEST_PUB" --id A002 --force
=> ERROR: Could not read the PKCS#8 file. Maybe it is encypted (--file-pin )

So basically I am not able to import the public key even that it is actually in the format mentioned in the answer above
