signature

Is there a way to determine programmatically if the currently running app was built and signed for development only or whether it was built for distribution? And can one determine if was build for app store or ad hoc distribution? Is it e.g. possibly to access the code signature and get the information from there? Or are there certain files present in one of variants that don't exist in the other ones? Is part of the bundle info? Or can it be derived from the executable file? Any hints are appreciated. It seems that the embedded.mobileprovision file is in ASN.1 format. The easiest way to check

I am trying to automate some emails using VBA for Excel. Everything so far is fine, except trying to keep my signature in the email. Once you tell VBA to create a new email, it will already contain your default signature. This can be seen if you try Outmail.Display . However if you overwrite the .HTMLBody property, it will be deleted. My simple attempt was to save the contents of .HTMLBody to a signature (string), and then reassign it to .HTMLBody just to test it out. However the resulting email will be void of any signature. Code to copy and re-insert the signature: Dim myOlApp As Outlook

I have a response from a 3-rd party web service. I load an XmlDocument with that response. string txt = readStream.ReadToEnd(); response = new XmlDocument(); response.PreserveWhitespace = true; response.LoadXml(txt); return response; Now I would like to verify that the respones is signed using the certificate. I have a VerifyXmlDoc(XmlDocument xmlDoc) method which I have found on msdn . I know that the message is correct. public bool VerifyXmlDoc(XmlDocument xmlDoc) { SignedXml signed = new SignedXml(xmlDoc); XmlNodeList signatureNodeList = xmlDoc.GetElementsByTagName("Signature"); signed

I am using following statement to create a RSA public and private key. openssl genrsa -out ksign_private.pem 1024 openssl rsa -in ksign_private.pem -pubout > ksign_public.pem Then I have program that uses, PEM_read_RSAPrivateKey, EVP_PKEY_assign_RSA, EVP_SignInit, EVP_SignUpdate, EVP_SignFinal functions from openssl libcrypto to generate signature file. I also have routine that verifies that signature can be verified using PEM_read_RSA_PUBKEY, EVP_PKEY_assign_RSA, EVP_VerifyInit, EVP_VerifyUpdate, EVP_VerifyFinal. Source code for these routines is attached below. When using these functions I

As all we do I have application which is signed by debug.keystore (by default) when it is in development mode (build). When it goes production we sign it with our private key. Is there any way to determine at runtime that current package is signed with debug.keystore (is in development mode) or is signed with our private key (is in production mode). I have tried something like PackageManager packageManager = getPackageManager(); try { Signature[] signs = packageManager.getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES).signatures; for (Signature signature : signs) { Log.d(TAG,

For all operation with Amazon services(S3, EC2, SimpleDB) You need to sign all resquest with HMAC-SHA-1 Signature( http://en.wikipedia.org/wiki/HMAC , http://docs.amazonwebservices.com/AWSFWS/latest/DeveloperGuide/index.html?SummaryOfAuthentication.html ). I'm working under asp.net backend and there is no problems. Problem is in the iPhone application. iPhone developer says that there is no way to use HMAC-SHA-1 encoding, and he have no rigths to implement his own algorithm. As programmer I cannot understand why there can be a problem. So I want too know is iPhone developer right? I've never

I've been working on a digital signature function for some days, now that I have everything working it is time to try to print the stamp in all pages but I'm not doing great... Trying to give a quick resume, to show the stamp what I do is creating PdfStamper, PdfSignatureAppearance and a Rectangle, then call the appearance.setVisibleSignature(rectangle, 1, "SIGNATURE") The second parameter "1" above is the page number that I want to show the stamp, it is okay to be 1 by now, as I tried to do in order to show stamp in other page was creating other instances of PdfStamper, PdfSignatureAppearance
