What is a CA certificate?
In cryptography, a certificate authority or certification authority ( CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made about the private key that corresponds to the certified public key. A CA acts as a trusted third party—trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. The format of these certificates is specified by the X.509 or EMV standard.

What is domain validation?
The commercial CAs that issue the bulk of certificates for HTTPS servers typically use a technique called " domain validation " to authenticate the recipient of the certificate. The techniques used for domain validation vary between CAs, but in general domain validation techniques are meant to prove that the certificate applicant controls a given domain name, not any information about the applicant's identity.
What is a CA client?
The clients of a CA are server supervisors who call for a certificate that their servers will bestow to users. Commercial CAs charge money to issue certificates, and their customers anticipate the CA's certificate to be contained within the majority of web browsers, so that safe connections to the certified servers work efficiently out-of-the-box. The quantity of internet browsers, other devices and applications which trust a particular certificate authority is referred to as ubiquity. Mozilla, which is a non-profit business, issues several commercial CA certificates with its products. While Mozilla developed their own policy, the CA/Browser Forum developed similar guidelines for CA trust. A single CA certificate may be shared among multiple CAs or their resellers. A root CA certificate may be the base to issue multiple intermediate CA certificates with varying validation requirements.
Why do we need a trusted certificate?
Trusted certificates can be used to create secure connections to a server via the Internet . A certificate is essential in order to circumvent a malicious party which happens to be on the route to a target server which acts as if it were the target. Such a scenario is commonly referred to as a man-in-the-middle attack.
Why do clients use CA certificates?
The client uses the CA certificate to authenticate the CA signature on the server certificate, as part of the authorizations before launching a secure connection. Usually, client software—for example, browsers—include a set of trusted CA certificates. This makes sense, as many users need to trust their client software.
Do CA certificates expire?
Browsers and other clients of sorts characteristically allow users to add or do away with CA certificates at will. While server certificates regularly last for a relatively short period, CA certificates are further extended, so, for repeatedly visited servers, it is less error-prone importing and trusting the CA issued, rather than confirm a security exemption each time the server's certificate is renewed.
What Does a Certificate Authority Do?
Basically, a public certificate authority is a publicly trusted entity that issues digital certificates to individuals, businesses, and other organizations. These certificates are basically small data files that contain vetted identifying information about the organization. So, CAs are a way to prove yourself to people who don’t know you (or your organization) personally by having a reputable third party vouch for you.
Why Do We Need Certification Authorities?
Why do you need a driver’s license or state ID card? Because it helps you prove that you’re you to third parties who wouldn’t know otherwise. A CA helps you to establish trust with others because they’re trusted for issuing valid, reliable certificates — and that trust is integral to public key infrastructure ( PKI). (We’ll speak more to PKI later.)
Why are third party certification authorities trustworthy?
Third-party certification authorities are inherently trustworthy for two main reasons: Public CAs are autonomous and not controlled by certificate requestors.

The PKI Certificate Authority Trust Hierarchy
Certificate Authorities are deemed trusted by browsers and devices based on their root certificate.
What is certificate based cryptography?
Certificate-based cryptography uses public-key cryptography to protect and sign data. Over time, attackers could obtain data that was protected with the public key and attempt to derive the private key from it. Given enough time and resources, this private key could be compromised, effectively rendering all protected data unprotected. Also the names that are guaranteed by a certificate may need to be changed over time. Because a certificate is a binding between a name and a public key, when either of these change, the certificate should be renewed.
How many bits is a CA certificate?
When using an RSA certificate for a CA, ensure that the key length is at least 2048 bits. You must not attempt to use an RSA certificate below 1024 bits for the CA. The CA service (certsvc) will not start if an RSA key of less than 1024 bits is installed.
How to protect CA private key?
Many organizations protect CA private keys by using a hardware security module (HSM). If an HSM is not used, the private key is stored on the CA computer. For more information, see Hardware Security Module (HSM) in Microsoft TechNet. Offline CAs should be stored in secure locations and not connected to the network.
What is a subordinate CA?
CAs that are not root CAs are considered subordinate. The first subordinate CA in a hierarchy obtains its CA certificate from the root CA. This first subordinate CA can use this key to issue certificates that verify the integrity of another subordinate CA. These higher subordinate CAs are referred to as intermediate CAs. An intermediate CA is subordinate to a root CA, but it serves as a higher certifying authority to one or more subordinate CAs.
How many characters are in a CA name?

What is an enterprise CA?
They publish certificates and certificate revocation lists (CRLs) to AD DS. Enterprise CAs use information that is stored in AD DS, including user accounts and security groups, to approve or deny certificate requests. Enterprise CAs use certificate templates. When a certificate is issued, the Enterprise CA uses information in the certificate template to generate a certificate with the appropriate attributes for that certificate type.
Can Enterprise CAs issue certificates?
These features are available only when the CA infrastructure is integrated with Active Directory. Additionally, only Enterprise CAs can issue certificates that enable smart card sign-in, because this process requires that smart card certificates are mapped automatically to the user accounts in Active Directory.

Providers
Worldwide, the certificate authority business is fragmented, with national or regional providers dominating their home market. This is because many uses of digital certificates, such as for legally binding digital signatures, are linked to local law, regulations, and accreditation schemes for certificate authorities.

Validation standards
The commercial CAs that issue the bulk of certificates for HTTPS servers typically use a technique called "domain validation" to authenticate the recipient of the certificate. The techniques used for domain validation vary between CAs, but in general domain validation techniques are meant to prove that the certificate applicant controls a given domain name, not any information about the applicant's identity.
Validation weaknesses
Domain validation suffers from certain structural security limitations. In particular, it is always vulnerable to attacks that allow an adversary to observe the domain validation probes that CAs send. These can include attacks against the DNS, TCP, or BGP protocols (which lack the cryptographic protections of TLS/SSL), or the compromise of routers. Such attacks are possible either on the network near a CA, or near the victim domain itself.
Issuing a certificate
A CA issues digital certificates that contain a public key and the identity of the owner. The matching private key is not made available publicly, but kept secret by the end user who generated the key pair. The certificate is also a confirmation or validation by the CA that the public key contained in the certificate belongs to the person, organization, server or other entity noted in t…
