Retain the author's information during reprinting. I am not familiar with the. NET platform. I have only recently been familiar with cracking and. NET platforms. I do not have a full understanding of the latest technologies and may no

Some days ago I find this information about (I can not remind where did I take it, maybe was from this forum) for install JCE and bouncycastle software for encryption. You shoshould first download change the policy of the JCE by downloading thisHttp://java.sun.com/j2se/1.4.2/download.html just jce a and unzip in a folder read the read me Doc so you shocould cut that 2 file and put here C: \ j2sdk1.4.2 _ 02

Previously, we introduced Disable SSID broadcast, restrict MAC addresses of wireless NICs to make the network more secure, and restrict MAC addresses. Disable wireless SSID broadcast to protect network security. Next we will introduce the wireless route WEP encryption method to protect wireless network security. 1. Configure wireless route WEP

Encrypt Microsoft Office files 1. Encrypt Word, Excel, and PowerPoint files The methods for encrypting these three types of files are similar. They can be implemented irregularly in the following two ways. Method 1: option settings In the preceding application window, such as Word2002), run the "tool options" command, open the "options" dialog box, switch to the "Security" tab, and set "Open permission ".Password"And" change the permission passwor

Here we only write out the main method, and call the main method. Don't forget to package it. /** * Java.

In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the

In spring security, configure a salt-encrypted service with a password of MD5:Private Md5passwordencoder encoder; Spring Security MD5Public Md5passwordencoder Getencoder () {Return encoder;}@Resourcepublic void Setencoder (Md5passwordencoder encoder) {This.encoder = encoder;}@Overridepublic void AddUser (user user) {Assign the encrypted password to user passwordSalt is user nameUser.setpassword (Encoder.enc

It is easy to use winrar for encryption, but it is still insecure if the method is not proper. For example, if the number of characters in a password is too small and the characters are too frequently used, it is especially dangerous to use only numbers, the attacker does not have to make much effort to crack the attack.It is easy to implement security encryption

the web. config of my own website on siteb, so that the cookie ciphertext of the target website can be easily unlocked. In order to ensure the security of this aspect, we have to make the cookie encryption and decryption part into a service, which is not only easy to update, but also allows as few people as possible to contact, to prevent security problems from

Use the document encryption software to encrypt the source code, and realize the source code to protect against leaks. The current practice is poor, the following failure cases can be verified:BYD, Yulong Communications, cool, Chinese communications and so on (are the same company do, the name will not say, ask users to know, Beijing. ）1) card, slow, blue screen, damaged data;2) The existence of loopholes,

) is determined when the Set Password and confirm setting password are equal. The value in the method is changed to the values that are processed by the new method (Md5encryption) in the new Class (Md5utils), with the following code:1 editor.putstring ("Password", md5utils.md5encryption (password));View Code①. In the Enter Password dialog (Showinputpwddialog), when you determine that the input password and the saved password are equal, you need to first process the entered password through the n

Label:General system Database Password encryption method: MD5 after the database is saved SHA1 Hash after deposit into the database disadvantage: Hackers can be password brute force to obtain password information, the practice is to hash the common password after making a dictionary,When cracked, only need to look up the dictionary to know the corresponding plaintext password.Recommendation: Use the following two password policies in a comb
