x509

I'm using XMLDSIG to sign a configuration file . I'd like my CA to be able to issue keys that can be used to sign XML. I'd then like to verify that the XML was signed with a key issued by my CA. How do I get the signing certificate out of the SignedXml object? How do I follow the certificate chain back to a specific CA? Note that the public key for my CA will be stored in my executable, rather than the certificate store. Roger Lipscombe To attach arbitrary certificates to an XML-DSIG file, add an <X509Data> element . To do this in .NET, use: signedXml.KeyInfo.AddClause( new KeyInfoX509Data

I am working on a task which is to get the client certificate when the user sends a request to the server. I have to get the certificate and get the 3 pieces of information from the certificate: user name, user's email address and user's firm name. At first it seems quite simple to just get the "Subject CN" for user name, "Subject E" for email address and "subject OU" for the company name. But later I realise there are a lot of different CA and tools and they issue certificate in different formats. For example, some certificate does not have email address field at all in the "subject" field

I have encountered a blocker with the .NET Framework version 4.5 to do with signing of XML with digital signatures. My problem is based around the need to sign individual XML elements with X.509 certificate with the RSA SHA-256 algorithm. I have read many .NET posts on this topic and it appears that there is a solution originally developed in the CLR Security project RSAPKCS1SHA256SignatureDescription.cs class. RSAPKCS1SHA256SignatureDescription has of course since been incorporated into the .net runtime and as of .NET 4.5 is now available under the distributed binary System.Deployment.dll. I

I have a public key in the following format -----BEGIN PUBLIC KEY----- xxxxxxxx -----END PUBLIC KEY----- I need to convert this into the following format -----BEGIN RSA PUBLIC KEY----- xxxxxxxxx -----END RSA PUBLIC KEY----- Basically, the issue is that I am working with a third party library which is written in Java. The third party library uses Java class "RSAPublicKeySpec" to generate an instance of type RSAPublicKey from a String. The String that I am supplying to this third party library is taken from a file which is in the following format: -----BEGIN PUBLIC KEY----- xxxxxxxx -----END

I have learned from the documentation that it is possible to sign git tags and commits. git config --global user.signingkey 0A46826A Docs: https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work This works for GPG. Has somebody done something like this with X509 user certificates? It looks like GPG is not compatible or interchangeable with x509 pki certificates. Since this is in a corporate environment GPG is not a option. It would be great if somebody could share thoughts or experiences how this could be done with x509 certs? What would be required and what it takes to implement something

Through the AWS Identity and Access Management, I have a user account to the AWS account of my CTO (who is credited with some money). I wanted to use this IAM user account to set up my own instances to ssh to it and run some BeautifulSoup python scripts. However, following this tutorial , when arriving to the part where I need to go on the Security Credentials page, I can't access this page and I'm told I do not have the authorization to view it. I checked my permissions with the IAM Manager, and I have administration rights, the highest possible clearance (so it seems to me). What can I do to
