sha256.scala.md

def sha256Hash(text: String) : String = java.security.MessageDigest.getInstance("SHA-256").digest(text.getBytes()).map(0xFF & ).map { "%02x".format() }.foldLeft(""){_ + _}

def sha256Hash(text: String) : String = String.format("%064x", new java.math.BigInteger(1, java.security.MessageDigest.getInstance("SHA-256").digest(text.getBytes("UTF-8"))))
