Abstract
A method and computer program to assign certificates/private keys to a token. This method and computer program allows a user to access a certificate authority and have certificates/private keys that are used for signature, encryption and role purposes generated and downloaded to the token. The use of secure communication lines and computers is not necessary since the token contains a unique token ID and private key, while the certificate authority contains the associated public key for the token. The certificate generated is wrapped in the public key and only the token, having the associated private key, may activate the certificate.
