But if you want to encrypt all the files in a folder, the number is not enough, if the number is not a lot of people exhausted? So today I'm going to tell you a good way to do this: Encrypt Windows 9x/2000 folders. By encrypting a folder, you can make all files in that folder protected. Th

Copy Code code as follows: Random number encryption Algorithm a^b = C, A^c =b, b^c = A xor or encryption Etual 2011-3-14 #include 7byte Data and 1byte key unsigned char code_buf[8] = {0x12,0x13,0x14,0x15,0x21,0x22,0x23,0x00}; void Print_buf (void) { int i; for (i=0;i{ printf ("%x,", Code_buf[i]); } printf ("\ n"); } int main (void) { unsigned char key,new_key; unsigned char Rand_digi; int i; printf ("Original buf is!\n"); Print_buf (); Key is a private key tha

Goldengate software has been used by many large enterprises for data disaster recovery. If used for off-site backup disaster, many are required to rent the public network of the transmission line, and many of these data are corporate secrets, in order to prevent confidential data is hackers to gain damage to the interests of enterprises, need to goldengate security to do some enhancements. In addition to establishing operating system and database-level security precautions, you can develop appr

More trojans and viruses are beginning to spread through the mobile hard disk or USB flash drive, the data inside the mobile hard disk becomes not so safe, ordinary antivirus software is difficult to solve the virus inside the mobile hard disk. So how do we protect the data in the mobile hard disk security? I give you a solution-mobile hard disk encryption. Mobile hard disk encryption is not a very advanced technology, just a little bit to move the mouse settings can be achieved. This method is

Brief introductionIn a real-world project environment, we do not store confidential text such as passwords in plaintext in the configuration file in case of theft. Spring Cloud Config provides an encryption method for encrypting plaintext text encrypted into ciphertext stored in a configuration file. Spring Cloud Config provides two types of encryption and decryption, one is symmetric encryption, and the other is asymmetric encryption. This article will show you how to use symmetric encryption f

asp.net| encryption uses ASP.net to encrypt passwords Whenever we want to build a database-driven personalized web site, we must protect the user's data. Although hackers can steal a person's password, the more serious problem is that someone can steal the entire database, and then immediately all the passwords. Principle It is a good practice not to store the actual passwords in the database, but to store their encrypted versions. When we need to

Preface:DPAPI is particularly useful because it can eliminate key management problems caused by password-based applications. Although encryption ensures data security, you must take additional steps to ensure key security. DPAPI uses the password of the user account associated with the calling code of the DPAPI function to derive the encryption key. Therefore, keys are managed by the operating system rather than applications.DPAPI can be used with computer storage or user storage (a user configu

Many netizens who use Foxmail (download) to send and receive mails often use encryption of their own accounts to protect private mails. However, due to the defect of Foxmail, you only need to encrypt your account, and your private emails do not have any security protection. You can view your privacy in just a few simple steps.

Several Popular encryption methods:The first is to use "SWF encrypt" or doswf Software Encryption. I personally think that SWF encrypt encryption is not very good, not because it is not powerful enough algorithms or something, but the hacker and other cracking software will specifically crack its encryption algorithm. This will cause your soon-encrypted SWF to be broken again. doswf is compiled by Chinese p
