Storing them in the same table as the password, or even another table of the same database, would mean that when hackers gain access to the database, they will have access to both the salt and the password hash. … Ease of use is the primary reason for keeping the salts in the same database as the hashed passwords.

How are passwords stored in database?
The password entered by user is concatenated with a random generated salt as well as a static salt. The concatenated string is passed as the input of hashing function. The result obtained is stored in database. Dynamic salt is required to be stored in the database since it is different for different users.
Where is the safest place to store passwords?
But there’s another alternative that’s simple, reliable, and everyone already knows how to use it: paper. To keep your passwords safe, just write them down on a piece of paper and put it in a safe place like your wallet. You can’t hack paper.
Which algorithm is best for storing passwords?
Passwords should be hashed with either PBKDF2, bcrypt or scrypt, MD-5 and SHA-3 should never be used for password hashing and SHA-1/2(password+salt) are a big no-no as well. Currently the most vetted hashing algorithm providing most security is bcrypt. PBKDF2 isn’t bad either, but if you can use bcrypt you should.
What is password salting?
Salting is simply the addition of a unique, random string of characters known only to the site to each password before it is hashed, typically this “salt” is placed in front of each password. The salt value needs to be stored by the site, which means sometimes sites use the same salt for every password.
Where can I save all my passwords?
Start or stop saving passwords
- On your Android phone or tablet, open the Chrome app .
- To the right of the address bar, tap More .
- Tap Settings. Passwords.
- At the top, turn Save passwords on or off.
Is it safe to write down passwords?
Yes, it’s true writing down all your passwords on paper and keeping that hidden in your home is more secure than a password manager. But that does not mean it’s better. People who write down passwords are more likely to reuse passwords. Password reuse is the worst thing you can do when it comes to passwords.
Is it safe to have Google save passwords?
Google Chrome keeps offering to save my passwords. Is it safe? A. Allowing the Chrome browser to save your login and password information for website accounts is safer now than it used to be with the Smart Lock security feature that Google introduced last year for its Chrome software.
Why you shouldn’t use a password manager?
An attack on your password manager can reveal all your passwords. This includes attacks on any device on which you store you managed passwords. Even if you’ve locked the password manager, an attacker will be able to get to them when you next unlock it on that device.
Is it safe to store passwords in the cloud?
Data stored on your computer feels safe. … However, passwords stored in the cloud are no more at risk of hacking, natural disasters, and power outages than locally saved passwords. The reputation of cloud providers is staked on their ability to protect the sensitive information of their customers.
How do hackers get hashed passwords?
Watching unencrypted traffic can often reveal a password hash. In a pass-the-hash scenario, systems will trust the hash and the password and let an attacker simply copy the hash without cracking it.
What file is used to store passwords?
Passwords were traditionally stored in the /etc/passwd file in an encrypted format (hence the file’s name).
What is the strongest hashing algorithm?
SHA-256 is one of the successor hash functions to SHA-1 (collectively referred to as SHA-2), and is one of the strongest hash functions available. SHA-256 is not much more complex to code than SHA-1, and has not yet been compromised in any way.
What is the purpose of salting passwords?
A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate hash table attacks by forcing attackers to re-compute them using the salts for each user.
How long should a password salt be?
Every salt should ideally have a long salt value of at least the same length as the output of the hash. If the output of the hash function used is 256 bits or 32 bytes, the length of the salt value should at least be 32 bytes.
Where is password salt stored?
Password Hashing add salt + pepper or is salt enough? The salt can and should be stored right next to the salted and hashed password. Additionally, the salt should be unique per password.
