The keys are mathematically related, and content encrypted by using one of the keys can only be decrypted by using the other. The private key is kept secret. The public key is typically embedded in a binary certificate, and the certificate is published to a database that can be reached by all authorized users. The X.

Thank you to all the developers who have used Stormpath. What is an X. Send the person who owns the certificate encrypted data that only they will be able to decrypt and read. To be fair, X. In this use case, you can think of an X. And as with national passports, you are very careful about who would ever have access to it — you would never give your passport away to anyone else.

It uniquely identifies you and only you. Because of this uniqueness, the government uses passports to verify who you are — you present it as a way of proving that you are a citizen of your country. And just as a national government acts as an authority for issuing and validating passports, something similar, called a Certificate Authority CA , exists for X.

A Certificate Authority is a 3rd party trusted by both you and anyone who might verify your identity. That is, when you use your X. Because the 3rd party trusts that the CA verified you, they in turn trust that your X.

There are well-known global and public Certificate Authorities, such as Verisign and Digicert. But a Certificate Authority can also be any party that both you and the person verifying you agree to as trusted. Many companies have their own private Certificate Authorities used to verify employee identities, for example.

Securing your data In addition to verifying your identity, X. It does this via a mathematical concept known as asymmetric key cryptography.

A key in this case is what you would think it would be — something used to lock or unlock a protective barrier. So when put together, asymmetric key cryptography basically means that one key is used to lock up data, but an entirely different key is used to unlock the data. The other of the two keys however must remain totally private to you, so no one will ever see it or be able to use it. If someone locks data with the public key, no one else who has the public key can unlock it — not even the person that originally locked it.

Only the person with the private key can unlock the data. That is why the public key can be given to and seen by anyone. As long as the private key remains safe, you can rest assured the data is locked safely. So if we had a public and private key, how would they be used? Naturally this is very sensitive information that should be for your eyes only. The bank can use your public key to encrypt your bank account balance. What does that have to do with X. Well, an X. Create an X. Anyone can create their own X.

But we can list the process of creating your own and having a CA verify it. Here is the high level overview of how one would create a validated X. This certificate is not considered a valid X. This file is what is known a valid X. The CA sends this newly created X.

After this final step, the user has their validated X. Search for.

This topic briefly explains X. In brief, a digital certificate is a part of a public key infrastructure PKI , which is a system of digital certificates, certificate authorities, and other registration authorities that verify and authenticate the validity of each party involved in an electronic transaction through the use of public key cryptography. A certification authority issues certificates and each certificate has a set of fields that contain data, such as subject the entity to which the certificate is issued , validity dates when the certificate is valid , issuer the entity that issued the certificate , and a public key. In WCF, each of these properties is processed as a Claim , and each claim is further divided into two types: identity and right. For more information about X. The primary function of a certificate is to authenticate the identity of the owner of the certificate to others.
