renamed Hash() -> HashBin()
HashBin() is using a binary output from OpenSSL now
previously we are using the hex output and with the new OpenSSL version
the text has additional characters and causes some problems
added: HashHex() - it is using the HashBin() and then converts the output
to hex format itself
