End entities

User and server certificates are required for mutual authentication on many HTTPS, SSL, and IPsec VPN network resources. You can create a user certificate on the FortiAuthenticator device, or import and sign a CSR. User certificates, client certificates, or local computer certificates are all the same type of certificate.

To view the user certificate list, go to Certificate Management > End Entities > Users. To view the server certificate list, go to Certificate Management > End Entities > Local Services.

The following information is available:

Create New	Create a new certificate.
Import	Select to import a certificate signed by a third-party CA for a previously generated CSR (see To import a local user certificate: and To import a server certificate:) or to import a CSR to sign (see To import a CSR to sign:).
Revoke	Revoke the selected certificate. See To revoke a certificate:.
Delete	Delete the selected certificate.
Export Certificate	Save the selected certificate to your computer.
Export Key and Cert	Export the PKCS#12. This is only available for user certificates.
Search	Enter a search term in the search field, then press Enter to search the certificate list.
Filter	Select to filter the displayed certificates by status. The available selections are: Active and Pending, Pending, Pending, Expired, Revoked, Active, and All. By default, only valid (active and pending) certificates are shown.
Certificate ID	The certificate ID.
Subject	The certificate’s subject.
Issuer	The issuer of the certificate.
Status	The status of the certificate.
Expiry	The expiration date of the certificate.

Certificates can be created, imported, exported, revoked, and deleted as required. CSRs can be imported to sign, and the certificate detail information can also be viewed, see To view certificate details:.

To create a new certificate:

1. To create a new user certificate, go to Certificate Management > End Entities > Users. To create a new server certificate, go to Certificate Management > End Entities > Local Services.
2. Select Create New to open the Create New User Certificate or Create New Server Certificate window.



3. Configure the following settings:

   Certificate ID		Enter a unique ID for the certificate.
   Certificate Signing Options
   	Issuer	Select the issuer of the certificate, either Local CA or Third-party CA. Selecting Third-party CA generates a CSR that is to be signed by a third-party CA.
   	Certificate authority	If Local CA is selected as the issuer, select one of the available CAs configured on FortiAuthenticator from the dropdown menu. The CA must be valid and current. If it is not you will have to create or import a CA certificate before continuing. See Certificate authorities.
   	Local User (Optional)	If Local CA is selected as the issuer, you may select a local user from the dropdown menu to whom the certificate will apply. This option is only available when creating a new user certificate.
   Subject Information
   	Subject input method	Select the subject input method, either Fully distinguished name or Field-by-field.
   	Subject DN	If the subject input method is Fully distinguished name, enter the full distinguished name of the subject. There should be no spaces between attributes. Valid DN attributes are DC, C, ST, L, O, OU, CN, and emailAddress. They are case-sensitive.
   	Name (CN)	If the subject input method is Field-by-field, enter the subject name in the Name (CN) field, and optionally fill-in the following fields: Department (OU) Company (O) City (L) State/Province (ST) Country (C) (select from dropdown menu) Email address
   Key and Signing Options
   	Validity period	Select the amount of time before this certificate expires. This validity period option is only available when Issuer is set to Local CA.

   	Key type	The key type is set to RSA.
   	Key size	Select the key size from the dropdown menu, either 1024, 2048, or 4096 bits.
   	Hash algorithm	Select the hash algorithm from the dropdown menu, either SHA-256 or SHA-1.
   Subject Alternative Name		Subject alternative names (SAN) allow you to protect multiple host names with a single SSL certificate. SAN is part of the X.509 certificate standard. For example, SANs are used to protect multiple domain names such as www.example.com and www.example.net, in contrast to wildcard certificates that only protect all first-level subdomains on one domain, such as *.example.com.
   	Email	Enter the email address of a user to map to this certificate.
   	User Principal Name (UPN)	Enter the UPN used to find the user’s account in Microsoft Active Directory. This will map the certificate to this specific user. The UPN is unique for the Windows Server domain. This is a form of one-to-one mapping.
   	URI	Enter the URI used to validate certificates.
   	DNS	Enter the DNS used to validate and sign the imported CSR.
   Other Extensions		This option is only available when creating a new user certificate, and when Issuer is set to Local CA.
   	Add CRL Distribution Points extension	Select to add CRL distribution points extension to the certificate. A DNS domain name must be configured. If it has not been, select Edit DNS name to configure one. See DNS. Note: After a certificate is issued with this extension, the server must be able to handle the CRL request at the specified location.
   	Add OCSP Responder URL	Enable Online Certificate Status Protocol (OCSP) to obtain the revocation status of a certificate.
   	Use certificate for Smart Card logon	Select to use the certificate for smart card logon. Enabling this setting will automatically enable Add CRL Distribution Points extension.
   Advanced Options: Key Usages		Some certificates require the explicit presence of key usage attributes before the certificate can be accepted for use.
   	Digital Signature	A high-integrity signature that assures the recipient that a message was not altered in transit
   	Non Repudiation	An authentication that is deemed as genuine with high assurance.
   	Key Encipherment	Uses the public key to encrypt private or secret keys.
   	Data Encipherment	Uses the public key to encrypt data.
   	Key Agreement	An interactive method for multiple parties to establish a cryptographic key, based on prior knowledge of a password.
   	Certificate Sign	A message from an applicant to a certificate authority in order to apply for a digital identity certificate.
   	CRL Sign	A Certificate Revocation List (CRL) Sign states a validity period for an issued certificate.
   	Encipher Only	Information is converted into code only.
   	Decipher Only	Code is converted into information only.
   Advanced Options: Extended Key Usages		Some certificates require the explicit presence of extended key usage attributes before the certificate can be accepted for use.
   	Server Authentication	Authentication will only be granted when the user submits their credentials to the server.
   	Client Authentication	Authentication is granted to the server by exchanging a client certificate.
   	Code Signing	Used to confirm the software author, and guarantees that the code has not been altered or corrupted through use of a cryptographic hash.
   	Secure Email	A secure email sent over SSL encryption.
   	OCSP Signing	Online Certificate Status Protocol (OCSP) Signing sends a request to the server for certificate status information. The server will send back a response of "current", "expired", or "unknown". OCSP permits a grace period to users or are expired, allowing them a limited time period to renew. This is typically used over CRL.
   	IPSec End System
   	IPSec Tunnel Termination	IPsec Security Associations (SAs) are terminated through deletion or by timing out
   	IPSec User
   	IPSec IKE Intermediate (end entity)	An intermediate certificate is a subordinate certificate issued by a trusted root specifically to issue end-entity certificates. The result is a certificate chain that begins at the trusted root CA, through the intermediate CA (or CAs) and ending with the SSL certificate issued to you.
   	Time Stamping
   	Microsoft Individual Code Signing	User submits information that is compared to an independent consumer database to validate their credentials.
   	Microsoft Commercial Code Signing	User submits information that proves their identity as corporate representatives.
   	Microsoft Trust List Signing	Uses a certificate trust list (CTL), a list of hashes of certificates. The list is comprised of pre-authenticated items that were approved by a trusted signing entity.
