Hello, I try to add two certificates to the smart card with the command pkcs15-init -T --store-certificate with the option --id, and I use the id 1000000 with the first certificate and I use the id 1000000 with the second certificate. When I try to add the second certificate I obtain that there is a certificate with the same id within the smartcard.
