It is possible for a person to have more than one digital certificate installed on their computer. The reason they can have multiple certificates is because there are both private and public versions created. The public versions are certificates which allow people to open and access different types of information which they have received or are attempting to access. Private versions are held by the organization or individual and are used to authenticate their public certificates.
Small Businesses Can Use a Third Party to Generate a Digital Certificate
A digital certificate can be issued by a trusted source, for smaller businesses. The third party should be recognized as an acceptable trusted source, as they will be creating and distributing your organization’s certificates. The reason small businesses use a third party is because they often lack the necessary resources to operate and manage their own in-house solutions. By using a third party, they are able to find cost-effective solutions, which otherwise would be out of their budget.
