Encrypted Data Storage ? HowTo ?Im trying to do a new app where i can store most of my passwords, basically
another "Password Keeper" style tool.... Question about this is what is the best way to store the data, as a plain XML or MDB is totally insecure im wondering what other choices i do have and how do i can implement them.. Forgot to mention that im using VB.net 2005... Thanks Why not look at Keith Brown's Password Minder program? He's a known
security expert and put a fair amount of effort into getting this right. He also publishes the source for the tool. http://www.pluralsight.com/tools.aspx Joe K.

The typical behaviour from a password is that you don't store them. Although some new fingertip and eye recognazion tools do that and are build for that like a key. And don't loose your key because than your house is open again. If it about the a password storage tool, than is a newsgroup not the best place how to do that. The method is than without sense because it is direct to search for in Google. There are many methods on MSDN, if I want to search for that, than I search for "Rijndael". In one of those I live. I hope this helps, Cor Show quoteHide quote "Microsoft" <creizl***@hotmail.com> schreef in bericht news:%23Zs4czkSGHA.1572@tk2msftngp13.phx.gbl... > Im trying to do a new app where i can store most of my passwords, > basically another "Password Keeper" style tool.... > Question about this is what is the best way to store the data, as a plain > XML or MDB is totally insecure im wondering what other choices i do have > and how do i can implement them.. > > Forgot to mention that im using VB.net 2005... > > Thanks > Hello!

With best regards, Eugene Mayevski You might consider the credit card storage aproach
i.o.w. a one way hash ,,,, the validation data is encrypted with a one way hash algorythm ,,, so the creditcard number that a users entest is also put through this same algorythm and compared to the validation data .. Advantage ,,, No one knows the actuall data except the user , even the database administrator can`t retrieve his password as it is not known to him ( you could even extend this technique to a XML or "flat" file ) here is a verry nice article to give you some idea`s http://www.devx.com/dbzone/Article/26726/0 regards Michel Posseth [MCP] Show quoteHide quote "Microsoft" <creizl***@hotmail.com> schreef in bericht news:%23Zs4czkSGHA.1572@tk2msftngp13.phx.gbl... > Im trying to do a new app where i can store most of my passwords, > basically another "Password Keeper" style tool.... > Question about this is what is the best way to store the data, as a plain > XML or MDB is totally insecure im wondering what other choices i do have > and how do i can implement them.. > > Forgot to mention that im using VB.net 2005... > > Thanks > Michel Posseth [MCP] wrote:
