    In a world of numerous mobile devices including smart phones, tablets, and even connected laptops, it’s important to implement secure techniques to safeguard them against the potentially harmful act of malicious attackers. Such an attack can render a vulnerable device useless, costing the user valuable data and time. To remedy this situation, the use of virtual private servers (VPS) is an effective way of ensuring both authenticity of these various devices in an environment.

    A VPS system allows multiple websites to be hosted on the same server. This is accomplished via an intermediate hypervisor, through which multiple levels of partition can be established. The hypervisor separates the administration of the different web-based applications, as well as various aspects of SSL certificates, while providing a protective environment for each one. There are startups of VPSs:physical and virtual. With physical VPS, users can access the root directory of the VPS using their username and password; however, with virtual private servers, users can access the root directory of the VPS without having to log in to the physical website server.

    Managing digital certificates is made simpler by the use of Let’s Encrypt tool. This tool will allow the browser to request a trusted Let’s Encrypt certificate from a CA, before making the actual SSL certificates requests. This ensures that a legitimate CA will be issuing the digital certificates, and only that CA is making the requests. Management of certificates becomes significantly easier once Let’s Encrypt is integrated into the website server. It also makes certificates more flexible and reliable.

    Some certificate providers prefer to automate the handling of digital certificates, but in some instances, human error is inevitable. However, even when humans make errors, automation always reduces the risks of human error to a great extent. When managing digital certificates, it pays to find a solution that will automate as much of the process as possible. The aim is to eliminate as many manual tasks as possible and keep the process as consistent and smooth as possible.

    There are several ways of managing digital certificates. startups and convenient way of managing digital certificates used by many companies is through the use of Lets Encrypt. Lets Encrypt is a CA that offers a completely free public-key infrastructure for all businesses to use as they wish. Once a business applies for a certificate, Lets Encrypt will create and digitally sign the certificate for the business. Once the certificate is digitally signed, it will become visible to the public-key infrastructure and anyone can access it.

    Another option for managing digital certificates is through the use of Lets Encrypt renewal services. This option works best for businesses with a large number of certificates or with expiry dates that are not easily met by the users. Lets Encrypt provides automatic renewal solutions and this allows a business to get automatic renewal quotes from Lets Encrypt without having to manually submit the renewals to each authority that they require. For example, a business needs to submit an application to get a certificate with a 3-year validity period, but if it does not get a valid certificate from one authority and the validity period is expired before the next renewal date, they will have to get a new one.

    Certificates expire over a period of time. An important advantage of Let’s Encrypt certificates is that they can be renewed automatically, but the downside is that sometimes certificates with expiry dates will receive a higher rate of rejection than others. Sometimes, it could be as low as a few percentage points, but if a large number of certificates with expiry dates are received during a short period of time, this can significantly increase the overall processing times of a website. To avoid such problems, certificate management systems can keep a database of expired certificates and alert an administrator when a new certificate is available so that the DNS server can update the DNS entries.

    Certificate Revocation is when a digital certificate is issued with a view to revoke the previous signature or private key. Once the certificate has been revoked, the administrator of the domain can change the expiration date of the certificate and issue a new one. This process is known as certificate revocation. Certificate Revocation is used mainly for security purposes but can be used for malicious purposes as well.
