title: Calculating SHA1 From Hex/Binary String in C#
body: <p>After 24 hours worth of programming I finally cracked, I want to make a C# WindowsForm application that shows you the value of a hashed hexstring input like in hashcalc.
  I could only make it for textstring input even after googling it.
  To demonstrate, the input 060201080808040602040909080909003583150369840500 should output d8f6b336a4df3336bf7de58a38b1189f6c5ce1e8
  and not a6879cb4510b18e8f41b3491ce474fd2ff9e2979
  Also this is for SHA1 Hashing so keep it only at that, Thanks!</p>
