Research on the keychain Storage Structure in iOS, ioskeychainKeychain is stored in the sqlite database in ios.Location of the database file:Real machine:/Private/var/Keychains/keychain-2.dbVirtual Machine:/Users/USER-HOME/Library/Developer/CoreSimulator/Devices/26DCA62C-B516-4DEA-A601-5C2D0EA07710/data/Library/Keychains/keychain-2-debug.dbIn a virtual machine, t

When we open apps, we usually keep some of the more important user information in the app, and many times we do it directly to Nsuserdefaults. The obvious drawback of this approach is that it is not safe enough to use code to encapsulate a class that stores more important information, such as user name account passwords, into Apple's own keychain, so that unless the entire iOS security mechanism is cracked, otherwise your storage will be relatively se

The iOS Keychain service provides a secure way to save private information (passwords, serial numbers, certificates, and so on). Each iOS program has a separate keychain store. starting with iOS 3.0, it becomes possible to share keychain across programs . It is convenient to use Apple's official keychainitemwrapper or sfhfkeychainutils.Apple already has ready-mad

User keychain on the saved or on the authentication password, but the user has logged into the system with a new password for one months, also do not remember the old password, so some apps will be asked to enter the Keychan password when launched. So we can only rebuild the keychain.* Close all applications and choose Go to Folder from the Go menu in the finder-> Library* Enter this path: ~/library/keychai

Udid is deprecated and is used as a unique identifier for the device. After obtaining the UUID, if you use Nsuserdefaults storage, and then reload after the program is unloaded, the UUID obtained is different from the previous. Use keychain storage to guarantee that the UUID will not change when the program unloads load. But when the machine is brushed or upgraded, the UUID will change. But this is still the best solution so far, and if there is a bet

Udid is deprecated and uses the UUID as a unique identifier for the device. Once the UUID is acquired, if it is stored with Nsuserdefaults, when the program is unloaded and then re-loaded, the UUID obtained is different from the previous. Using the keychain storage ensures that the UUID does not change when the program unloads load. However, the UUID will still change when the machine is being brushed or the system is upgraded. But this is still the b

In general, we use Nsuserdefaults to store data information, but for some private information, such as passwords, certificates, and so on, we need to use a more secure keychain. The information stored in the keychain will not be lost due to the deletion of the app, still valid after the user re-installs the app, and the data is still available.Using Apple's official release of the Keychainitemwrapper or sfh

IOS KeyChain comprehension and code examples Understanding of KeyChain, refer to http://my.oschina.net/w11h22j33/blog/206713 In this article, the KeyChain is used to save the user name and password. The user name is placed in the attribute and the password is placed in the password item. I personally think there is a problem with the addition, deletion, modificat

PreviousArticleI have reprinted a message about how to use keychain to store and read information. Later, I saw multiple applications on the materials, and how to share a keychain, such as Baidu's multiple applications. Use the same account and password. It is not necessary for each application to have an independent password. Therefore, multiple applications are used to share the same

Previously encountered a problem, in the use of some Linux distribution, with Ssh-keygen generated a good key pair and uploaded to the target server, but each login to re-enter.This is related to Ssh-agent, see the following man ssh-agent output:Ssh-agent is a program to hold private keys used for public key authentication (RSA, DSA). The idea isThat Ssh-agent was started in the beginning of a x-session or a login session, and all other windows orPrograms is started as clients to the Ssh-agent p

Keychain is stored in the SQLite database on iOS.Location of this database file:Real machine:/private/var/keychains/keychain-2.dbVirtual machines:/users/user-home/library/developer/coresimulator/devices/26dca62c-b516-4dea-a601-5c2d0ea07710/data/library/ Keychains/keychain-2-debug.dbIn the virtual machine, this database can not read the test, very strange.Each of

During simple login and registration interface design, users often encounter access design issues with user names and passwords. Other solutions are not discussed here. Now we will introduce a relatively simple method-keychain. You can find the keychain, keychainitemwrapper. H, and keychainitemwrapper. M files in the generickeychain instance. But now we only need to perform simple user name and password acc

Normally, we use Nsuserdefaults to store data information, but for some private information, such as passwords, certificates, and so on, we need to use a more secure keychain. The information stored in the keychain is not lost because the app is deleted, and is still valid after the user has reinstalled the app, and the data is still there. Using Apple's official Keychainitemwrapper or sfhfkeychainutils is

The iOS certificate is divided into two chunks, the development certificate and the publishing certificate, and the corresponding development profile and release profile.In the development release iOS app, to apply for a variety of certificates, creating these certificates in the developer Center is troublesome, the most gas is the developer Center access speed is slow, often in order to create a certificate to spend a lot of time, but also to the Mac computer

Today with Xcode Packaging IPA file to colleagues, the results prompt import, prompt certificate missing, find a half-day did not find the problem, and then open the keychain, found that the certificate is all expired!!!

Apple has banned UUID applications since January 1. So we need to replace it with some methods. Below I will replace the uuid with the keychain access. For the keychain application, Apple provides an example program named generickeychain. Here: Example. 1. Import the Security. Framework file to the database and import the keychainitemwrapper. h and keychainitemwrapper. M files to the project, and reference
