How to list pkcs11 url of the private key?

[rrottmann]

For signing an intermediate CA with openssl, I need to state the pkcs11 URL in the config file. I can list the public keys but fail to do so for the private keys:

p11tool --list-all pkcs11:model=PKCS%2315%20emulated;manufacturer=Pol%20Henarejos;serial=ESPICOHSMTR;token=Pico-HSM%20%28UserPIN%29
Object 0:
        URL: pkcs11:model=PKCS%2315%20emulated;manufacturer=Pol%20Henarejos;serial=ESPICOHSMTR;token=Pico-HSM%20%28UserPIN%29;id=%01;object=RSA2K;type=public
        Type: Public key (RSA-2048)
        Label: RSA2K
        Flags: CKA_WRAP/UNWRAP;
        ID: 01

Object 1:
        URL: pkcs11:model=PKCS%2315%20emulated;manufacturer=Pol%20Henarejos;serial=ESPICOHSMTR;token=Pico-HSM%20%28UserPIN%29;id=%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00;object=ESPICOHSMTR;type=public

Error in crt_list_import (1): Error in provided PIN.

Is this the correct way to get those URLs? Any alternatve to get those?

I found the following workaround:

1. List keys with pkcs11-tool -l --pin 648219 -O and identify the serial of the private key
2. Convert to %-notation: echo 6b522326270f20107f64a431fbee050d9f29f977 | tr [:lower:] [:upper:] | sed 's/../%&/g'
3. Use a minimal pkcs11 URL: pkcs11:id=%6B%52%23%26%27%0F%20%10%7F%64%A4%31%FB%EE%05%0D%9F%29%F9%77;type=private
