Mail.jar: This jar file contains the JavaMail API and Sun-provided SMTP, IMAP, and POP3 service providers; Activation.jar: This jar file contains the JAF API and the Sun implementation. 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

available for both the authentication certificate and the admission ticket to the server. The figure on the right shows the entire Kerberos authentication process. 2. How to obtain the "subscription Certificate "? First, let's take a look at how the client obtains the "subscription certificate ". 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

Use the Javax.mail.Transport tool class to send mail.Here is the specific code:Method One:/** * @ClassName: Authentication * @Description: Authenticator * @author: CHENRL * @date: October 30, 2015 9:59: */ public class authentication extends Authenticator { String username=null; String Password=nul

Verification for eapol-key, that is, four handshakes. TK is used for subsequent data encryption. The four 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 respectiv

Let's get down to the point where the Client obtains its own and KDCSession Key (SKDC-Client)Generate your own Authenticator and the name of the Server to be accessed and useSKDC-Client. Then it is sent to KDC together with TGT. KDC usageMaster KeyDecrypts TGT and extracts Client Info andSession Key (SKDC-Client)And then use thisSKDC-ClientDecrypt the

Now, let's assume that they represent two different types of messages, which we'll cover in the following protocol. You can argue that the 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 cond

Authenticator: like the Java.net class, JavaMail API can also use Authenticator to access protected resources through the user name and password. For the JavaMail API, these resources are the mail server. JavaMail Authenticator is in the Javax. mail package, and it is d

When a user sends a request to a server with authentication features, the server authenticates the user identity. Generally, the user name and password are verified based on various authentication protocols. The Windows Media Service

client needs to buy a ticket first, but this ticket cannot be purchased directly, and a warrant is required. The client needs to obtain a subscription Certificate in advance before buying a ticket. KDC is available for both the authentication certificate and the admission ticket to the server. The figure on the right shows the entire Kerberos authentication process.2. How to obtain the "subscription Certificate "? First, let's take a look at how the client obtains the "subscription certificate

There are two methods in the Session object: Getdefaultinstance (Prop,authenticator), GetInstance (Prop,authenticator), Both of these methods have a co

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

JavaMail (1): Use JavaMail to send a simple email and javamail to send JavaMail provides developers with programming interfaces related to email processing. It is an API released by Sun to process emails. It can easily perform some common mail Transmission.

. Authorization verification aims to prevent others from sending emails randomly and reduce the generation of spam. In the previous blog, I used the Transport connect (host, port, username, password) method for verification. In fact, we can also perform verification when obtaining the Session object. There are two methods in the Session object: getDefaultInstance (prop, authenticator) and getInstance (prop, authen
