Redmine

Hi people,

After spending a long time searching for the answer, i gave up and decided to post the doubt.

I'm a .NET developer and developing an application for read issues from determinad user. What i need is to authenticate the user for get his issues. I saw in the users table that the password field is hash enconded. I read some posts about validate the password and in the SHA1 php method is passed as parameter a "salt" variable i think, but i don't know where to get this variable.

Is it possible to authenticate using some redmine webservice? Or how can i get that salt variable for decode the password?

Thanks in advance

Jonathan
