hi Please try this in Developer console
  
string before = '!';
Blob beforeblob = Blob.valueOf(before);
string paramvalue = EncodingUtil.base64Encode(beforeblob);
System.debug(before + ' is now encoded as: ' + paramvalue);
Blob afterblob = EncodingUtil.base64Decode(paramvalue);
System.debug(paramvalue + 'is now decoded as: ' + afterblob.toString());
