Upon opening the project in the udpated Xcode, I found that the target read 'Base SDK Missing'. I fixed that by following the instructions here . Now when I try building targeting any version of iOS, I receive this error (with the corresponding version referenced in the error text): CodeSign Error: code signing is required for product type 'Application' in SDK 'Device - iOS 4.1' I have the Team

Member, Customer, Admin all models share some required fields (eg. email and password) each model may have some unique fields (eg. company for Customer only) some fields may be shared but not have the same validation (eg. name is required for Customer but optional for Member) all fields must be filled during the registration process, so the forms are different the login form should be unique

I had a bit of confusion about the carry and overflow flags which I think I've nailed, but I wanted to put it to the community to check that I'm right. Basically, from what I can see, the ALU in the Z80 doesn't care about signed/unsigned operations, it just adds bits. This means that if two 8-bit values are added together and cause a 9-bit value as a result of their addition, the carry flag will be set. This includes adding two negative two's complement numbers,

This is the code I was trying to use, but I get a System.Security.Cryptography.CryptographicException "Invalid algorithm specified." . X509Certificate pXCert = new X509Certificate2(@"keyStore.p12", "password"); RSACryptoServiceProvider csp = (RSACryptoServiceProvider)pXCert.PrivateKey; string id = CryptoConfig.MapNameToOID("SHA256"); return csp.SignData(File.ReadAllBytes(filePath), id); According

What do I need to know? Where will I find an API ( .jar and documentation)? What are the steps I need to follow in order to sign data and verify the data? Please provide me code snippet if possible. 回答1: I reckon you need the following 2 Bouncy Castle jars to generate the PKCS7 digital signature: bcprov-jdk15on-147.jar (for JDK 1.5 - JDK 1.7) bcmail-jdk15on-147.jar (for JDK 1.5 - JDK 1.7) You can download the

This cannot be cheese? or I ran rake routes and confirmed that all the routes are valid. Also, in my routes.rb file I have devise_for :users and root :to => "home#index" . I get the following routing error when clicking the "Sign out" link: No route matches "/users/sign_out" Any ideas what's causing the error? 回答1: I think the route for signing out is a DELETE method. This means that your sign out link needs to look like this: :delete %>

I do not add the message itself to the signature to minimize the signature length (which is exactly 32 Bytes). However, when I create the signature with openssl: $ cat test.txt | openssl dgst -ecdsa-with-SHA1 -sign sample.key -keyform DER > act.bin OpenSSL obviously puts the message itself to the signature resulting in a larger signature (e.g. 39 Bytes). I can verify the signature with Crypto++ if I set CryptoPP:
