How to Decrypt Encrypted Password?
Hi,
I am in a trouble while decrypting my encrypted Password assigned to my project file, the problem is that, my colleague has given a software to Encrypt the password i used that and managed to Encrypt the password instantly i again try to decrypt that for security purpose whether it is working properly or not but it happens inversely, i was failed to decrypt that please help me.
Any help would be appreciated.

- Use namespace System.Security.Cryptography.
- Declare an UTF8Encoding object.
- Declare an object of MD5CryptoServiceProvider compute hash keys and compute the hash key for the variable.
Hope this will suffice your need.
Re: How to Decrypt Encrypted Password?
The theory goes that the password encryption is a one-way process. By this I mean that it is not computationally feasible to decrypt it.
The way that this works is that when a user enters a password, it is encrypted and compared with the encrypted version in the file.
The user is only allowed in if the two encrypted versions match.
There is no way to recover a lost password, the only option is to issue a new temporary password to the user, the encrypted version of the new password replaces the old. The user should then change his/her own password so that only they know it.
Only a brute force method can be used to find out the contents of a password file, for example by encrypting a dictionary file and comparing the encrypted version against each password. This will only work if the user has used a dictionary word as a password, hence the recommendation to use both characters and numbers in a password. Such programs however run for days and days and cannot be guaranteed to decrypt all carefully chosen passwords. Besides, this is not what you want to do, is it?
