How to use Base64 to encode and decode a string in Scala

Answer 1

object Base64EncodeDecode_Scala {
  def base64Encode(str: String): String = {
    val bytes = str.getBytes("UTF-8")
    java.util.Base64.getEncoder.encodeToString(bytes)
  }

  def base64Decode(encodedStr: String): String = {
    val bytesArray = java.util.Base64.getDecoder.decode(encodedStr)
    new String(bytesArray, "ASCII")
  }

  def main(args: Array[String]): Unit = {
    val base64EncodeStr = base64Encode("scala programming")
    
    println(base64EncodeStr)
    
    println(base64Decode(base64EncodeStr))
  }
}
