title: How to SHA1 hash a string in Android?
body: <p>In Objective C I've been using the following code to hash a string:</p>
  
  <pre><code>-(NSString *) sha1:(NSString*)stringToHash {    
      const char *cStr = [stringToHash UTF8String];
      unsigned char result[20];
      CC_SHA1( cStr, strlen(cStr), result );
      return [NSString stringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",
          result[0], result[1], result[2], result[3], 
          result[4], result[5], result[6], result[7],
          result[8], result[9], result[10], result[11],
          result[12], result[13], result[14], result[15],
          result[16], result[17], result[18], result[19]
          ];  
  }
  </code></pre>
  
  <p>Now I need the same for Android but can't find out how to do it. I've been looking for example at this: <a href="https://stackoverflow.com/questions/5757024/make-sha1-encryption-on-android">Make SHA1 encryption on Android?</a>
   but that doesn't give me the same result as on iPhone. Can anyone point me in the right direction?</p>
