Has anyone used Buzz Andersen's Simple iPhone Keychain code?

阅读更多关于 Has anyone used Buzz Andersen's Simple iPhone Keychain code?

You can find it here. I'm trying to understand his sample code in order to write a simple program with that stores passwords into the keychain and retrieves them for login. Has anyone done this before? It would be most appreciated if I can see any examples you may have. There's really no code to demonstrate, he lists both calls there. Heres's an example, for what it is worth: NSError *error; [SFHFKeychainUtils storeUsername:@"fred" andPassword:@"mypassword123" forServiceName:@"myService" updateExisting:YES error:&error]; NSString *storedPassword = [SFHFKeychainUtils getPasswordForUsername:@

Get the Username(s) stored in Keychain, using only the ServiceName? OR: Where are you supposed to store the Username?

阅读更多关于 Get the Username(s) stored in Keychain, using only the ServiceName? OR: Where are you supposed to store the Username?

问题 So the OS X Keychain has three pieces of information: ServiceName (the name of my app) Username Password I obviously always know the ServiceName. Is there a way to find any saved Username(s) for that ServiceName? (Finding the password is easy once you know the Username.) I would much prefer to use a nice Cocoa wrapper such as EMKeychain to do this. But EMKeychain requires the UserName to get any keychain item! + (EMGenericKeychainItem *)genericKeychainItemForService:(NSString *

阅读更多关于 Using SecKeyRawSign on the iPhone

问题 I'm trying to sign some data using SecKeyRawSign but I keep getting a -4 errSecUnimplemented. That seems strange since the documentation states that it is available in iPhone OS2.0 and later. Has anyone been able to use this function? If so, are there any tricks involved? ~Nate 回答1: If you're having this problem, most likely it is because the private key you generated isn't actually being saved into the keychain. I figured this out when stopping and restarting the application and signing the

How to save CFUUID in keychain

阅读更多关于 How to save CFUUID in keychain

问题 I'm developing an iPhone application. The application access some web service that aboug other things should recognize the device ID. Since UDID is deprecated, I need to call CFUUIDCreate to generate my own UUID for this purpose.

Besides, I want this identifier to survive re-install. Using the keychain to store that UUID seems like an

OpenSSL and Apple Keychain integration

阅读更多关于 OpenSSL and Apple Keychain integration

问题 We're using a multi platform application which should run on both Windows and Mac. Our application is based on OpenSSL as the SSL and related stuff supplier. It uses Client Certificate to establish secure connections and to identify the end user. We want to use Windows and Mac native certificate storages to ensure maximum security. Openssl has an engine to interact with Windows' Certificate Store (CAPI engine). However, we didn't manage to find such a solution for Mac's Keychain. Is there an

Google plus sign-in for xcode share extension

阅读更多关于 Google plus sign-in for xcode share extension

I’m writing an iOS app to share web page links by email, and as part of it I want users to be able to sign in to google plus. I’ve got the containing app working fine using the instructions from here: https://developers.google.com/+/mobile/ios/sign-in and now I’m trying to add a share extension that can also access the user’s google+ profile. I started off by trying to add the sign in button in to the share extension, but I don’t think that’s going to work because after clicking the button you’re taken out of the app to the browser to accept permissions, and then there’s no way to redirect

How to store your github https password on Linux in a terminal keychain?

阅读更多关于 How to store your github https password on Linux in a terminal keychain?

问题 This is becoming even more important now with the new 2-factor authentication, as one has to create a new token each time a password is required on the terminal. Basically, I'm looking for an equvalent to the osxkeychain available in OS X that I could use on Linux desktops and servers: git config --global credential.helper osxkeychain I searched through the possible solutions, but so far I don't like any of them: ssh instead of https - not recommended and links not easily accessible on GitHub
