A sensible PasswordStrengthRegularExpression

阅读更多关于 A sensible PasswordStrengthRegularExpression

问题 We're using the standard ASP.NET authentication provider (AspNetSqlMembershipProvider as it happens) and the defualt password strength requirement is a little excessive for our needs. We require our users to enter a password that is alphanumeric at least (i.e, letters and at least one number mandatory, mixed case and non-alphanumeric characters if the user so desires). Can anyone suggest what PasswordStrengthRegularExpression setting would achieve this? Also, how can we control the error

问题 The following Haskell program prompts the user for a password in the terminal and continues if he has entered the correct one: main = do putStrLn "Password:" password <- getLine case hash password `member` database of False -> putStrLn "Unauthorized use!"

Best practice for storing database password

阅读更多关于 Best practice for storing database password

问题 I am developing a custom server application that will access a database. I need to decide where I will store the credentials (and to address) to that server. A common solution is to put the credential in a config file. However, I do not want a compromised server to mean that the hacker has access to the DB (which is hosted on a separate server). I could store the credentials in the environment, but that is just security through obscurity. Mr. Evil can just look in the environment to find it.

How does your company do “Enterprise” Password Management?

阅读更多关于 How does your company do “Enterprise” Password Management?

问题 We've talked about personal password management here but how do you guys manage your passwords at a company wide level? 回答1: We have managed to plan our company applications so they are mainly web based and open source or in-house developed. This then allowed us to use LDAP to hook into active directory for logging into our intranet. From there we modified the logins into various products we use (MediaWiki, Wordpress, SugarCRM etc.) so that if the user is authenticated in the intranet, they

Enter passwords interactively in R or R Studio (Server)?

阅读更多关于 Enter passwords interactively in R or R Studio (Server)?

问题 Is there a way in R to enter passwords interactively to the command line and hide them from the screen? I know there's readLine , but I do not know passwords can be hidden there. Assume you want to connect to a database using ROracle or RMySQL and do not want to store the password in a script but rather make the user enter it every time a query is executed. Yes, we had a similar question around here, but I feel that the situation has changed and it's worth to address to problem again.

Should Password fields retain their values if a form does not pass validation?

阅读更多关于 Should Password fields retain their values if a form does not pass validation?

I have a typical sign-up form with two password fields. <form> <%= Html.TextBox("Email", null) %> <%= Html.Password("password", null) %> <%= Html.Password("confirmPassword", null) %> <input type='submit' /> </form> If the form fails validation and is redisplayed, the text field retains its value but the password fields are always blank. Why shouldn't the password fields retain their values? And more importantly, is there any reason I shouldn't override this behavior? I feel like this behavior decreases usability, and would prefer password fields to behave the same way as textbox fields --

Best practice on generating reset password tokens

阅读更多关于 Best practice on generating reset password tokens

问题 Any best practice on how a reset password token should be constructed? I'm thinking: random 17 characters [a-zA-Z0-9] + a globally unique id + random 17 characters [a-zA-Z0-9]. Is there a better solution, or an industry standard on reset password tokens? 回答1: There are some important points to consider. The code should be really random (read from MCRYPT_DEV_URANDOM), and should not be derrived from other user related information. Ideally the code is base62 encoded (A-Z a-z 0-9) to avoid

Spring security Oauth2 Resource Owner Password Credentials Grant

阅读更多关于 Spring security Oauth2 Resource Owner Password Credentials Grant

Have just installed spring security oauth2 in my eclipse IDE. The service am trying to implement will be consumed by second party users through their installed applications hence i chose to use password grant type. As per my understanding of Oauth2 the following request should work for the demo sparklr2 service without the need of me encording the username and password parameters. i.e POST http://localhost:8080/sparklr2/oauth/token?grant_type=password&client_id=my-trusted-client&scope=trust&username=marissa&password=koala but i keep getting <oauth> <error_description> Full authentication is
