An RSA token is a type of security used in different computing environments. It the past, this type of token was contained on a smart card. However, today since all computers have USB ports, this type of token is now placed directly onto USB drives. When you log into a secure connection, the site checks to make sure you have proper access. It does this by first comparing your user name and password to the ones it has stored. Next, it looks for the token contained on the USB drive and uses the encrypted data within the token to perform a second level of authentication.
An RSA Token Can Contain Both Digital Certificates and Digital Signatures
An RSA token, like those available here at Digi-Sign, can be used for different purposes, as it can contain digital certificates as well as digital signatures. A digital certificate contains different types of encrypted data which lets two computers talk to one another and verify that the connection is secure. A digital signature is also encrypted and can be used to sign different types of documents, forms, contracts, and even email messages.
