best password security

share modulo n.RSA's small exponential attack. One suggestion to improve RSA speed is to make the public key e take a smaller value, which makes encryption easier to implement and faster. But this is unsafe, and the answer is that both E and D take a larger value.RSA algorithm is the first algorithm that can be used in both encryption and digital signature, and it is easy to understand and operate. RSA is the most widely studied public-key algorithm, from the proposed to now nearly 20 years, ex

Your Windows logon password, which is entered every time you start the machine, does not effectively protect your files. The intention of setting a logon password is not to protect your files, but to prevent others from entering your computer in your name. Why is this important? Because on your computer, only the operations you allow can be performed, such as reading emails. Unless you have set the mailbo

When selecting a password, try to rewrite a sentence so that you can easily remember it. For example, "chang'e 2 was successfully launched this year's national day !" Then select the first pinyin letter for each word and it becomes "jngqjceehcgfsl". Is it long enough? But it is not strong enough. Then, change the first word to uppercase, and change "e" of "2" to the upper key of 2, that is, "@" and the last "l ", change to the number "1! Finally, it

In the development, the official environment of the database account, password, secret key is how to store? stored in the configuration file?stored in environment variables? This allows developers to see these passwords. How can you get fewer people to know these key passwords?

7.2. Password sniffing Although attackers do not use network communication between your users and applications for access control, they must be aware that data exposure is becoming more and more important, especially for authentication information. Using SSL can effectively prevent HTTP requests and responses from being exposed. Requests to any resources using the HTTPS scheme can prevent password sn

In an Oracle database system, there are two ways to authenticate users if they want to log on to an Oracle database as a privileged user (Internal/sysdba/sysoper): Using authentication that is integrated with the operating system or using the Oracle database password file Verification. Therefore, the management of password files, for the control of authorized users from remote or local login Oracle database

Talking about the cipher algorithm, some people will feel strange, but a mention of PGP, most of the online friends are very familiar with, it is a tool software, registered to the certification center can be used to encrypt the file or digital signature, PGP is the RSA algorithm, we will discuss it later. The purpose of the cryptographic algorithm is to protect the confidentiality, integrity and security of the information, simply to say that the ant

If you follow the SQL Server database server login process carefully, you will find that the password calculation is actually very fragile, the SQL Server database Password Vulnerability embodies two aspects: 1, password encryption algorithm when the network login 2, the database stored password encryption algorithm.

The problem caused by domain conventions is that password settings do not comply with the rules of the Policy Group. In this case, you need to set the response option in the domain policy to reduce the complexity of the password. (By default, the complexity must be at least 7 characters long and contain multiple letters and numbers) Windows Server 2003 solutionYes: Choose Start> program> Administrative Tool
