问题 Ok, I have an application written in C#. We have data in an SQL Server. Among that data we have user accounts, which will give access to the application. I've read around, and I know that you should salt and hash and possibly hash a bunch of times, etc. But, where do I do what? What do I send to and from the SQL Server? Exactly what do I store in the database? Do I hash it in SQL? (possibly a hash function there, like in mysql?) Do I hash and do the fancy stuff in my code? Do I send the hash

Many thanks to sundar for the ForegroundColor trick. I'm not sure if it matters whether you use Project.Log or go direct to Console.WriteLine(), any NAnt ninjas want to educate me?

问题 When encrypting a file with OpenSSL, it is possible to use -pass pass:mySillyPassword, where mySillyPassword is the password used in encryption. In addition, it is possible to use a salt, where -salt -s (hex string) is used to specify the salt. Why would someone want to use a password instead of the salt or in conjunction with a salt? Also, I understand just using the -salt command will cause OpenSSL to generate a salt. How is this better than a user-defined salt? If OpenSSL randomly
