title: What character set do hash functions (eg. MD5, SHA) use...
body: <p>...I'd like to ask how is it, and hopefully not asking an alrady asked question (I searched for it on the internet for a week, didn't find it... I know it's hidden somewhere in those long books... so if it's here please direct me to the thread, ty)... </p>
  
  <p>...I'd like to know what character base... or how exactly is it with character base which is used in hash functions like MD5, SHA... for example... what do they use base64, ascii, extended ascii... cose if I try to encode for example char alt 444 (╝) it encodes it... but there has to be a limit right, to how many indifferent chars can be used... cose otherwise the hash could not be unique, right? And many sites using these algorithms only let you use base64 character pool... I guess... please help... thank you</p>
