How do I install a root certificate? Given a CA certificate file 'foo. Ubuntu: First, copy your CA to dir /usr/local/share/ca- certificates/sudo cp foo. My work has decided to issue their own certificate authority (CA) to handle different aspects of our work securely without paying for certificates. Cryptographically. This guide describes certificates created with a Microsoft CA and also contains steps for when you use a self-signing certificate which is supported as of Cisco. @Infinity: The issue of trust did occur to me as well but in the end I think this is no different to us trusting any other existing root CA in Windows. Root 5. VeriSign Class 3 Public Primary CA - G4. Description: While this root is not being used today for Symantec's commercial certificate offerings, it is an ECC. CA storesudo update- ca- certificates. That's all. You should get this output: Updating certificates in /etc/ssl/certs.. Running hooks in /etc/ca- certificates/update. Adding debian: foo. No file is needed to edit. Link to your CA is created automatically. Please note that the certificate filenames have to end in . This procedure works also in newer versions: manuals. FAQ: Security | Mono. Secure Socket Layer (SSL) / Transport Layer Security (TLS)That’s probably because you do not trust the site you are connecting to. ![]() Note that a default installation of Mono doesn’t trust anyone! You can confirm this by using the tlstest tool (needs Mono > = 3. It prints an error if something is wrong. System. dll /r: Mono. Security. dll. mono tlstest. There are four alternatives to solve this problem: (Recommended) Starting with Mono 3. Mono’s certificate store with the system certificate store. It should run automatically when you install the official Mono packages. Make sure the ca- certificates- mono package is installed. Implement a ICertificate. Policy class. By doing this you can override the normal results of the certificate validation (e. However you are now responsible of applying your own trust rules for your application. Further suggestions and source code are available in the Using. Trusted. Roots. Respectfully article. Use the certmgr. exe tool (included in Mono) to add the root certificates into the Mono Trust store. Every SSL certificate signed from this root will then be accepted (i. SSL usage (for all Mono applications running for the user or the computer - depending on the certificate store where the certificate was installed). Use the mozroots. Mono 1. 1. 1. 0 and later) to download and install all Mozilla’s root certificates (i. Fire. Fox and other Mozilla’s softwares). It’s easier than finding a specific root but it’s also less granular to make a decision about which one(s) you install or not. I imported the root certificate but it still doesn’t work. HTTPS, like many protocols using SSL/TLS, doesn’t requires the server to send its root certificate when negotiating the handshake. In this case it won’t be possible to use certmgr - -ssl to download automatically the root certificate into Mono’s certificate stores. You’ll need to either: find the root certificate and install it manually with certmgr; oruse the mozroots tool to install all (or part of) Mozilla’s root certificates. This has a high probability to install the required root certificate - but will also install a lot of extra roots (about 1. How can I debug https traffic? Use the webscarab tool and set the http_proxy environment variable to the address of the webscarab server, this will allow you to watch the traffic unencrypted. I got the root certificate but it doesn’t install.Some Certificate Authorities (CA) still use very old root certificates signed with the MD2 digest algorithm.MD2 is old enough not to be part of the standard .NET framework. This makes it impossible to validate the root certificate digital signature.To correct this you must enabled MD2 support in your machine. Windows Installer Keeps Trying To Install Sonic Activation Module . This is possible because the Mono. Security. dll assembly contains a managed MD2 implementation to ensure compatibility with older certificates. The following XML snippet must be added, inside the inside the < configuration> element of your machine. MD2 OID (object identifier) with the hash algorithm implementation.< mscorlib>. Settings>. < crypto. Name. Mapping>. Classes>. < crypto. Class mono. MD2="Mono. Security. Cryptography. MD2. Managed, Mono. Security. Version=1. Culture=neutral, Public. Key. Token=0. 73. Classes>. < name. Entry name="MD2" class="mono. MD2" />. < /crypto. Name. Mapping>. Map>. < oid. Entry OID="1. 2. 8. MD2" />. < /oid. Map>. < /cryptography. Settings>. < /mscorlib>. Why does SSL use certificates ? SSL encrypts data - but encrypting data to an untrusted server doesn’t improve much security. You need to know who is on the other side of the socket! SSL use X. 5. 09 certificates for the purpose of binding a public key with an entity (in this case the web server). The server gets its certificate from a certificate authority (CA) who certify that the key belongs to its owner. Finally you must trust that CA to do its job properly. Are SSL client certificates supported ? Both Ssl. Client. Stream and Ssl. Server. Stream, in Mono. Security. Http. Web. Request doesn’t due to a strange design/relationship between the 1. Windows/Crypto. API (i. API to associate a certificate with a private key). This should be fixed in the 2. X5. 09. Certificate class has been extended to provide this association. Also recent versions of XSP do support SSL/TLS and client certificates. See the Using. Client. Certificates. With. XSP article for more details. Does SSL work for SMTP, like GMail ? Yes it does. First you must import the root certificates using the mozroots tool: mozroots - -import - -ask- remove. Note that if you are using a web application (i. Next you need to import the intermediate certificates. You can do this by using the certmgr tool to connect to the SSL server. E. g. certmgr - ssl smtps: //smtp. Use the - m option to import the certificates into the machine store if required. Finally you need to make sure to use the SSL- enabled port in your application. This is generally 4. FIPS Certification. What is the status of FIPS 1. The Mono cryptographic stack is not FIPS 1. If you absolutely must use FIPS 1. FIPS 1. 40 certified from managed code (say, wrapping NSS). Alternatively, if you have a certified implementation and the wrapper, you can instruct Mono to automatically use your new implementation by using the machine. Are there any efforts to bind external libraries that are FIPS certified? There is an ongoing effort part of Mono called the Crimson project, you might want to contribute to that effort. Authenticode(r) Code Signing. Does Mono support Authenticode(r) signatures ? Yes. Mono supports Authenticode signatures for assemblies. As assemblies are PE files this also means that Mono support signing any kind of PE file, e. EXE, DLL, OCX, SCR …Does Mono support Authenticode(r) signatures on CAB file ? No. CAB files aren’t PE file. While the signature mechanim is probably much alike the CAB format is very different from the PE format. Mono doesn’t requires CAB files at this time (and may never will) so support for signing/verifying CAB files is unlikely to appear (unless someone feel likes contributing it). What does “signature can’t be traced back to a trusted root!” means ? The default installation of Mono doesn’t trust any root certificate authority (CA). While verifying a signed PE file the chktrust utility will try to find a trusted root and if it cannot will display the following error. Mono Check. Trust 1. Verifying file sample. Authenticode(tm) signatures.. WARNING! sample. exe is not timestamped! ERROR! sample. exe signature can't be traced back to a trusted root! You can use the certmgr tool to add the code signing root certificate in the Mono trust certificate store. Public Key Infrastructure (PKI)Is Mono fully compatible with RFC2. RFC3. 28. 0 ? No. Mono support a limited subset of PKIX certificate path building and validation. This is enough to support simple cases like SSL/TLS and Authenticode(r). Version 2. 0 of the . NET framework includes improved support for PKI, e. X5. 09. Chain class, so better support for PKI is on the Mono roadmap. Why doesn’t Mono includes root certificates from X, Y and Z ? There are two main reasons not to include “defaults” root certificates in Mono. Digital certificates are, like many digital files, copyrightable. This means that there are restrictions on how the roots certificates can be distributed. We aren’t in the business to decide on who you are going to trust. Certificates Authorities exists all around the world. The ones best suited to you aren’t necessarily the ones best suited for everybody else and having a terribly long list of “trusted” roots isn’t a very secure solution. So where can I download them ? Too many CA, too many places. The most common ones are (in alphabetical order): An easier alternative is to use the mozroots tool to download and install all Mozilla’s root certificates. The downside is that it’s more difficult to handpick only the one you really require. Can I make my own certificates ? Mono includes the makecert tool that can be used to create test (i. The tool is generally used to create code- signing (i. Authenticode) certificates but can also be used to create both server and client SSL certificates. Creating a SSL server test certificatemakecert - r - eku 1. CN=pollux" - sv pollux. OID for server- side authentication and pollux is your host name.
