the existing Mail account to send MAIL tools, for example, I registered a mailbox account in NetEase, through JAVA Mail control, I can not personally log on to Netease mailbox, allow the program to automatically send emails using Netease mail. This mechanism is widely used in registration activation and spam sending. JavaMail can be used. The general process of JAVA mail sending is as follows: 1. Construct a specific class that inherits from javax. mail.

The core classes used in JavaMail packages are: Properties, session, message, address, authenticator, transport, Store, etc. 3. Message transfer process As shown in the figure above, the e-mail processing steps are as follows: Creates a session object. The session object crea

. Authentication Sequence Until now, we only see how to verify a suject in the program code. Now let's take a look at what happens inside Shiro when a verification occurs. We still use the architecture diagram we have seen in the architecture section. Only Authentication-related components on the left are highlighted. Each number represents one step in authentication: Step 2:The program code calls the subject. login method to pass the user's identity and proof to the constructor of the authe

handshakes are based on eapol-key. The eapol-key structure is as follows: PTK generation To generate a PTK, five necessary elements are required: PMK, anonce (nonce 1), snonce (nonce 2), authenticate MAC (Mac 1), and supplicant MAC (MAC 2 ). For example: The two nonce values are random numbers generated by authenticator and supplicant respectively. The output of this topology contains four parts. In fact, data encr and data mic are combined as the

to adding Kerberos to this step. At the same time, it should be noted that SKDC-Client is a Session Key with its own lifecycle, and TGT is associated with the Session. When the Session Key expires, TGT becomes invalid, after that, the Client has to apply for a new TGT from KDC. KDC will generate a different Session Key and a TGT associated with it. At the same time, because the Client Log off also leads to SKDC-Client failure, SKDC-Client is also calledLogon Session Key. Next, let's take a look

consensus agreement requires two different rounds of agreement, in which prepare represents a round of agreements, and commits represent the second round. There is also another deterministic condition, which he describes when the client can determine that some particular hash block is a definite number. This is easy to understand and we continue to express the only definite conditions in the current version of the Casper study. If some particular epoch has a list of signed messages, then a hash

Here, the warrants have a proprietary name, TGT (Ticket Granting Ticket), while TGT is an important Service of KDC-Authentication Service (KAS: Kerberos Authentication Service ). When a user attempts to log on to a host by entering the domain account and password, the Kerberos service of the local machine sends an authentication request to the authentication service of KDC. The request consists o

Today, I learned about JavaMail. It is really troublesome to send an email to javamail. The core classes used to process emails in the JavaMail package are Session, Message, Address, Authenticator, Transport, Store, and Folder. Session defines a basic mail Session, which needs to read information similar to the mail server, user name, and password from Properties. In addition, the JavaMail API frameworks include James and Spring Mail.For future conven
