. 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 ". 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 att

Getdefaultinstance (Prop,authenticator),

Both of these methods have a common parameter authenticator, which is a
filtered. match (Regular Expression capturing group) is the parsing result of the selector logical segment (for example, [arr = "111"] is parsed as arr, ", =, 111 According to the regular expression ), in the selector logical fragment, ATTR, CHILD, and PSEUDO, you must call preFilter to correct the match.
PreFilter: {// match is the capture group // assume: [arr ^ = 'val'] "ATTR": function (match) {// The first capture group of attr is arr, which transcodes it into the original character match

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
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
