Dear all,

I need to do the project and meet some difficulties and need your help.

I need to maintain the password security table.
I want to change the password to another characters and can recovered to be
real password using some algorithms.

Do you have any algorithms of encrypt and decrypt?

Thanks for your help,

Mr. Hing

Hello, Raymond!

..NET provides a set of cryptography algowithms.
Have a look at the followfing article

Dear All,

I have used the algorithm given by vadym stetsiak in codeproject web site.
It works fine but I meet the error in the following line of decrypt.

Dim resultArray As Byte() = cTransform.TransformFinalBlock(toEncryptArray,
0, toEncryptArray.Length)

It always said that it is invalid length.
Even I change to be toEncryptArray.Length-1, it still does not work.

Please help,

Thansk,

Mr, Hing.

Hey,

I wrote a tutorial on how to use the cryptographic services in .NET to
encrypt and decrypt files. But you can easily strip out the file code and
just work with the password string:

Hope it helps.
