Update password of user → net user username newpassword Windows commands for user and password modifications:Īdd user → net user /add username -key=”password” Regardless of the approach being used, it is appropriate to state that password hashes are NOT SAFE if in the hands of an ill-will hacker. In case of complex passwords, there are free tools which use a brute-force approach of comparing hashes of multiple combinations of text. These tables are called rainbow tables or hash tables. You would need to create a hash of a guessed password and compare to the extracted hash to determine if you have guessed correct.įree online tables are available which store password hashes of common passwords which can make a hackers job lot easier if people are not serious about password complexities. I use the word ‘guess’ because remember hashes are one-way functions, you cant decode them like you can do to an encrypted string. Hackers are cognizant of this process and have lot of tools in their arsenal to efficiently guess the passwords from the hashes. This protects clear-text passwords from internal application developers and also from hackers in case they are able to breach the database. Instead of storing passwords in the back-end database in clear text, password hashes are used. If the hashes match, B can be rest assured that the original message has not been corrupted on the way.Īpplication engineers also use this technique for securing passwords of users logging into their systems.
When B receives the message, it also creates a hash of the text message using same SHA-2 algorithm and compares it with the hash provided by A.
For example, when A sends a text message to B, it first creates a SHA-2 ( popular hashing algorithm) hash of the message and sends it along with the message. This hash value is used to verify the integrity of original text when it is sent over a communication medium. This is a one-way function meaning the original text file cannot be generated back from the hash value.

Hashing is a software process of generating fixed character length hash values for a text file.
