Quick validation digital SSL certificates rely on domain registration information to validate the certificate owner. Their intended purposes are for server certificates such as courier smtp and purftpd services. They often will not carry a third party financial warranty and convert less customers. If you operate a blog, content management system or any other type of web application requiring a securely encrypted login, these certificate types are best suited for your needs. Make sure the email and telephone number on the domain registration is current before ordering these types of certificates.
