 Q: Which X.509 certificates are recognised by IT4Innovations?
 -------------------------------------------------------------
+
 Any certificate that has been issued by a Certification Authority (CA) from a member of the IGTF ([http:www.igtf.net](http://www.igtf.net/)) is recognised by IT4Innovations: European certificates are issued by members of the EUGridPMA ([https://www.eugridmpa.org](https://www.eugridpma.org/)), which is part if the IGTF and coordinates the trust fabric for e-Science Grid authentication within Europe. Further the Czech *"Qualified certificate" (Kvalifikovaný certifikát)* (provided by <http://www.postsignum.cz/> or <http://www.ica.cz/Kvalifikovany-certifikat.aspx>), that is used in electronic contact with Czech public authorities is accepted.
 
 Q: How do I get a User Certificate that can be used with IT4Innovations?
 ------------------------------------------------------------------------
+
 To get a certificate, you must make a request to your local, IGTF approved, Certificate Authority (CA). Usually you then must visit, in person, your nearest Registration Authority (RA) to verify your affiliation and identity (photo identification is required). Usually, you will then be emailed details on how to retrieve your certificate, although procedures can vary between CAs. If you are in Europe, you can locate your trusted CA via <http://www.eugridpma.org/members/worldmap>.
 
 In some countries certificates can also be retrieved using the TERENA Certificate Service, see the FAQ below for the link.
 
 Q: Does IT4Innovations support short lived certificates (SLCS)?
 ---------------------------------------------------------------
+
 Yes, provided that the CA which provides this service is also a member of IGTF.
 
 Q: Does IT4Innovations support the TERENA certificate service?
 --------------------------------------------------------------

  Yes, ITInnovations supports TERENA eScience personal certificates. For more information, please visit [https://tcs-escience-portal.terena.org](https://tcs-escience-portal.terena.org/), where you also can find if your organisation/country can use this service
 
 Q: What format should my certificate take?
 ------------------------------------------
+
 User Certificates come in many formats, the three most common being the ’PKCS12’, ’PEM’ and the JKS formats.
 
 The PKCS12 (often abbreviated to ’p12’) format stores your user certificate, along with your associated private key, in a single file. This form of your certificate is typically employed by web browsers, mail clients, and grid services like UNICORE, DART, gsissh-term and Globus toolkit (GSI-SSH, GridFTP and GRAM5).

 Q: What are CA certificates?
 ----------------------------
+
 Certification Authority (CA) certificates are used to verify the link between your user certificate and the authority which issued it. They are also used to verify the link between the host certificate of a IT4Innovations server and the CA which issued that certificate. In essence they establish a chain of trust between you and the target server. Thus, for some grid services, users must have a copy of all the CA certificates.
 
 To assist users, SURFsara (a member of PRACE) provides a complete and up-to-date bundle of all the CA certificates that any PRACE user (or IT4Innovations grid services user) will require.

 DN stands for Distinguished Name and is part of your user certificate. IT4Innovations needs to know your DN to enable your account to use the grid services.

 Most grid services require the use of your certificate; however, the format of your certificate depends on the grid Service you wish to employ.
 
 If employing the PRACE version of GSISSH-term (also a Java Web Start Application), you may use either the PEM or p12 formats. Note that this service automatically installs up-to-date PRACE CA certificates.

 Q: What is a proxy certificate?
 -------------------------------
+
 A proxy certificate is a short-lived certificate which may be employed by UNICORE and the Globus services. The proxy certificate consists of a new user certificate and a newly generated proxy private key. This proxy typically has a rather short lifetime (normally 12 hours) and often only allows a limited delegation of rights. Its default location, for Unix/Linux, is /tmp/x509_u*uid* but can be set via the $X509_USER_PROXY environment variable.
 
 Q: What is the MyProxy service?
 -------------------------------
+
 [The MyProxy Service](http://grid.ncsa.illinois.edu/myproxy/) , can be employed by gsissh-term and Globus tools, and is an online repository that allows users to store long lived proxy certificates remotely, which can then be retrieved for use at a later date. Each proxy is protected by a password provided by the user at the time of storage. This is beneficial to Globus users as they do not have to carry their private keys and certificates when travelling; nor do users have to install private keys and certificates on possibly insecure computers.
 
 Q: Someone may have copied or had access to the private key of my certificate either in a separate file or in the browser. What should I do?
+--------------------------------------------------------------------------------------------------------------------------------------------
 
 Please ask the CA that issued your certificate to revoke this certifcate and to supply you with a new one. In addition, please report this to IT4Innovations by contacting [the support team](https://support.it4i.cz/rt).
