A lot of hacker intrusion personal website is an important way to get the administrator account and password through the SQL injection vulnerability, and then openly into your management backstage, upload asp or PHP Trojan Horse, and then the right administrator or do something else.
But for hashing (MD5 message digest algorithm) encryption a little bit to understand the webmaster should know that the vast majority of database storage passwords are encrypted after MD5 encryption, the current situation with the ability of the individual can not be cracked, but why our password can still be cracked?
My site before the time was hanging horse, but also for this very puzzled, can hash be cracked it? win. So I went to some hacker website to download the teaching video, found that these hackers favorite site is cmd5.com, this site is specifically for MD5 password cracking encryption, the site's database contains a large number of known clear text of the comparison table, The average 6-bit plaintext MD5 value is easily cracked. But what if we use a 18-digit password to clear it? This website certainly cannot crack, come, we operate
Casually write a 18-bit string, and then encrypt the site, and then fill in the text box, Huo, good boy, this can be cracked ...
Carefully tried several times before discovering, as long as the site is encrypted in plaintext, no matter how long you can successfully decrypt, is because once the site encrypted, will be clear text and ciphertext corresponding to store in the database, so that if there is a corresponding ciphertext input requirements to decrypt, will be transferred to the corresponding plaintext, Do not believe you can try, in other sites encryption, then decrypt the site, the general more than 10-bit irregular string decryption success probability is very small, but do not encrypt the site, otherwise, your password is not a password, remember this, you do not have to fear to be exploded Administrator account number and password, Bold you can even release your password, let them decipher it, of course, the premise must be like this password: ajiuyt45_-!! Dfsdiuehf2@22jds
This format of the password is basically not decrypted, remember, as long as you do not query the cmd5.com above the plaintext of the password, this is the most important I was because of curiosity on the site to query the plaintext of my password, hackers used .... Alas
1 password must be greater than 12 digits, preferably uppercase + lowercase letter + digit + symbol
20 million do not go to cmd5.com query your password MD5 value, once the query should immediately replace the password
30 million remember the first, do not be afraid to remember, do not worry about trouble, such as your site was hung horse, traffic plummeted, when the income plummeted when your trouser pockets cry.
Write these for the first time, do not know can publish, hehe, actually feel admin5 should increase the website security column, now has this kind of column is the hacker website, stationmaster own website how can not have.
