As you know, SSH defaults to authentication by default, even if you use an SSH key instead of a password. As a single factor in the way of authentication, once the key leaks, the same will also compromise the security of the server. To address this issue, we will show you how to enable SSH multi-authentication for Ubuntu Server (mfa,multi-factor authentication). When enabled, you need to verify that you have a different authentication factor for your computer or mobile phone when you log on to

message class, which is a subclass of messages. It contains the subject (title) of the message, the content, the recipient address, the sender's address, and you can also set up a copy-and-drop, or even an attachment. Transport: Used to send mail. It is the transmitter. Hello world of 4.3 javamail When you use Telnet to send mail, you also need to deal with the problem of Base64 encoding yourself, but use javamail to ignore these problems, are handled by JavaMail. First step: Get session Sessio

to the exception prompt user error message; 3, the last call Subject.logout to exit the operation. Several issues as tested above: 1, the user name/password hard-coded in the INI configuration file, later need to change to such as database storage, and password needs to encrypt storage; 2, the user identity token may be not only the user name/password, there may be other, such as login to allow the user name/mailbox/Mobile phone number at the same time login. 2.4 Identity Verification process

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

Which encryption algorithm is 100% secure? OTP! OTP (one-time-pad, one password at a time) is the only password proved to be undeciphable in mathematics. OTP is generally only used in situations where secrets are extremely important: military and diplomatic affairs. However, because the key length is very long and it is very difficult to store and exchange keys s

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

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 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

BASE32 decoding algorithm in the Google phone token is not populated with the ' = ' number.
