Fails on verifying signature - RSA_padding_check_PKCS1_type_1:invalid padding

[Pedro Lopes <pedroterrosolopes@xxxxxxxxx>]

Hello,

I'm generating a key pair in a smartcard (as a session object), then I convert both keys to RSA openssl objects.

Then I save both into different files.

I tried use these keys to sign and verify (private encrypts and public decrypts).

When I try to verify the signature, fails with RSA_padding_check_PKCS1_type_1:invalid padding.

I run following commands:
echo "test" > "test.txt"
openssl rsautl -sign -in test.txt -inkey privKey.pem -out sig
openssl rsautl -verify -in sig -inkey pubKeyp8.pem -pubin

Below pub and priv key:
