Using Digital Certificates to Create Trustworthy Emails

In computer security, a digital certificate, also called an identity certificate or digital key, is an electronically signed document used to demonstrate the authenticity of a key. A certificado digital simple usually consists of three components: a signature algorithm, a challenge-response algorithm and a signature file. The signature file, which may be stored on the computer desktop or in the user's registry, and the challenge-response part of the algorithm allow for cryptograms to be created dynamically. A challenge-response element also known as an autoresponder enables a user to enter a response back to a received challenge, thus creating a cryptogram. The advantage of these cryptograms is that they provide greater flexibility and portability than traditional keys and certificates.

For example, to send an email to another user with a digitally signed digital certificate, the email sender will have to know the private key that belongs to the second user. However, since a digital certificate does not contain a secret key like a key or password, the sender of the email cannot derive the secret key to derive the email address belonging to the second user. Similarly, to access the digital certificate of another user, the user usually has to enter his email address along with a secret key. This makes it impossible for the third party to use the email address for fraudulent purposes. Apart from these obvious security benefits, there are other benefits that are more subtle.

The most obvious benefit of digital certificates is that they provide an extra layer of security over the traditional security certificates that have been used for decades. Traditional certificates use a series of algorithm to encrypt information, but digital certificates only use one key, thus reducing the risk of impersonation, a common problem. Digital certificates also protect organizations from hacking. Because digital certificates do not contain secrets, they are much harder to imitate or copy. If a hacker steals your digital certificate, he would have no way of re-keying your email account or impersonating you.

Another advantage is that a digital certificate can help to set a different track record for your email address. By using a different email address when you request a credit card or a loan, or by changing your email address to a completely different one, you can establish a new line of credit or loan history. In addition, a certificado digital SII often contains information that helps to determine the validity of the record, such as the issuing company's name, the expiration date, and whether the signature on the certificate is valid.

Digital certificates, unlike passwords, are what make emails secure. A hacker can impersonate you by pretending to be someone else, but an email with a digital certificate is harder for him to copy because it contains a "keyspace" of different random numbers and letters, making it almost impossible to reproduce. A digital certificate also makes it harder for a person to send you spam email and phishing mail. Digital certificates are usually issued by browsers, making it impossible for someone who does not trust your email address to have access to your email.

To request a free digital certificate for your email address, go to one of the websites that offer them. Fill in the request, and you will receive a short code that you use in the browser to access your certificate. Then you will be provided with a key, a password, and your email address. You can then create your email and access the website securely from there. Digital certificates are a great way to make your email address trustworthy.
