![]() According to Wikipedia "As of 2015, there are no published attacks on Salsa20".īest regards, Irrationally Diligent Software Developer. To predict a password, one would need to crack Microsoft's cryptographic random number generator and predict the entropy (if used).Īlternatively, if someone would crack the Salsa20 cipher, one could predict a password from the previous password. The stream cipher is used as a random number generator by repeatedly feeding its output as its input ( Salsa20Cipher.cs line 176-196).That hash is used as encryption key for a Salsa20 stream cypher ( CryptoRandomStream.cs line 119).A SHA256 hash is generated from the random value with entropy ( CryptoRandomStream.cs line 114-118).I haven't bothered to find out where this entropy comes from (usually unpredictable user behavior like mouse movement or keypresses are used for this), but apparently it isn't assumed that entropy is always available. ![]() The generated random number is combined with some additional entropy if available.It uses the standard RNGCryptoServiceProvider from the. Overall, there are 95 distinct characters the password generator can choose from. They can also contain spaces, but spaces will never appear at the beginning or end of the password. A random number is genrated ( PwGenerator.cs line 65). By default, the passwords generated by pwgen are 64 characters long and can contain any uppercase or lowercase letter, number or symbol found on a US keyboard.It uses the class CryptoRandomStream from KeePassLib\Cryptography\CryptoRandomStream.cs with the stream cipher Salsa20 used as a random number generator. Looking at the sourcecode of KeePass 2.30, the password generator seems to be implemented in KeePassLib\Cryptography\PasswordGenerator\PwGenerator.cs. But even with that knowledge, the generated passwords are still far, far too strong to brute-force.īut how exactly are the passwords generated? If it would be a predictable pseudorandom number generator, that might be an attack point. Download New Password Generator and enjoy it on your. This makes it slightly easier to crack than if the length would not be known and if they would expect that you also use special characters. Read reviews, compare customer ratings, see screenshots and learn more about New Password Generator. Password Tech (formerly PWGen) is a password generator capable of creating. That tells them the length and the character set. secure password manager KeePass Password Safe (Classic Edition) is a secure. When an attacker knows you use KeePass, then they might also assume that you use the standard settings for the password generator.
