JavaBeans Activation Framework and add the Activation.jar file to the CLA.Third, use:1. Some core classes of Javamail.jar: Session, Message, Address, Authenticator, Transport, Store, Folder. And some of the other commonly used classes contained in the Javax.mail.internet package.2. Session mail reply, send and receive email is based on this reply. The session object takes advantage of the Javax.util.properties object to obtain the mail server, user n

Introduction to the Java Mail delivery function implementation1, Java Mail Introduction:Java Mail is the use of existing mail accounts to send mail tools, for example, I registered an email account in NetEase, through the control of Java mail, I can not personally login NetEase mailbox, let the program automatically use NetEase mailbox to send mail. This mechanism is widely used in such aspects as registration activation and the sending of spam messages.2. Configure the JavaMail development envi

then close the connection.The basic method of sending () is to connect to the mail server at each call, which is inefficient for sending multiple emails on the same mail server.Note: If you need to monitor the MAIL command during mail sending, you can set the debug flag before sending:Session. setdebug (true ). G. Store and folderConnectSession is used for receiving and sending emails. However, after obtaining the session, we need to obtain a specific type of store from the session, and then co

Use filter to prevent users from accessing some unauthorized resources. The filter intercepts all requests/response,Then put a token that passes the verification in the user's session, and then the filter determines whether to allow response each time based on the token.

TOTP, but the YubiKey was still limited to storing-credentials.Software-based competitors, like the Google Authenticator app for Android, can store any number of credentials.It's where the smartcard features can make up some of the difference.The NEO includes a Common criteria–certified Javacard secure element, which can be loaded with several Javacard applets. One of the applets developed by Yubico are an OATH implementation so can store multiple TO

handshake messages are based on Eapol-key, and the Eapol-key structure is as follows:PTK how to generateGenerating PTK, requires 5 necessary elements, Pmk,anonce (nonce 1), Snonce (nonce 2), Authenticate Mac (Mac 1), supplicant mac (Mac 2). Such as:The 2 nonce is the random number generated by authenticator and supplicant respectively.The output in this diagram contains 4 parts, in fact the data encr and data mic together are the TK mentioned earlier

cache, which also means that the amount of code execution will be greatly reduced, the number of access to the database will be greatly reduced, and so on.So it's good to combine private and shared caches (client-side caching and public/gateway caching). However, this kind of caching is more suitable for more static resources, such as tablets, content pages , and often changes in the data of the API is not very appropriate . If the API adds a piece of data, then for the 10,000 clients, the cach

Structure Shows the detailed structure of Shiro: Subject: as described above. SecurityManager: as described above. Authenticator (Authenticator) is an internal component responsible for executing user logon and performing corresponding actions. When a user attempts to log on, the logic is that the Authenticator is performing this action.

to traditional hardware token devices, it also has soft tokens used on smart devices, which is very convenient. However, for small and medium enterprises, the cost of using commercial identity authentication solutions such as RSA is high. The lack of IT budget often limits enterprises' choice of two-factor solutions. The Google Authenticator Project is a software implementation that can be used to generate one-time passwords on multiple mobile platf
