Syntax

nsoftware.SecureBlackbox.Utils

Remarks

If you need to resolve a hostname to an IP address, encode a string using a specific character encoding, or compose a multipart message, look no further. This is exactly what Utils is intended for. Below is a summary of little useful features that this class can help you with.

Encoding and decoding

• Encode binary data to base64 and decode it back (Base64Encode and Base64Decode)
• Hex-encode and decode (HexEncode and HexDecode)
• Encode and decode dates - particularly handy when working with other suite components that expect string dates (StringToDate, DateToString)
• Convert object identifiers from and to string representation (StringToOid, OidToString)
• Convert string to any supported character encoding (StringEncode and StringDecode).

Networking helpers

• Get local network parameters with GetLocalIP and GetLocalDNSName
• Resolve remote domain names into IP addresses (GetRemoteIP)
• URL-encode and decode HTTP and other data (UrlEncode and UrlDecode).

Work with multipart MIME messages

• Compose a multipart body with AddPartFromBytes and SaveMultipartToBytes
• Load and process existing multiparts with LoadMultipartFromBytes and GetPartToBytes.

Utils class also offers a useful GetErrorDescription method that lets you obtain a human-readable message for every SecureBlackbox error code you might get. // base64Encode byte[] bytes = ("Life is like riding a bicycle. To keep your balance," + " you must keep moving. (Albert Einstein)").getBytes(); String base64Encoded = utils.base64Encode(bytes,false); System.out.println(base64Encoded); // base64Decode String decoded = new String(utils.base64Decode(base64Encoded,false)); System.out.println(decoded); // Example: Using another SecureBlackbox component to get a string // and convert it to a Java Date object MessageVerifier verifier = new MessageVerifier(); verifier.setInputFile("signedMessage.bin"); verifier.setOutputFile("output.txt"); verifier.verify(); String verifiedDate = verifier.getValidatedSigningTime(); // Retrieving the string: 2024-05-17 13:25:26 Date date = utils.stringToDate(verifiedDate); // Using utils to convert it System.out.println(date); // Output : Fri May 17 13:25:26 CEST 2024 // Retrieving remote IP String hostName = "nsoftware.com"; System.out.println("Hostname: " + hostName + " has this IP: " + utils.getRemoteIP("www.nsoftware.com",false,dmAuto,"",60)); // Output: Hostname: nsoftware.com has this IP: 52.168.9.41 // Hex Encode byte[] bytes = ("Genius is one percent inspiration and " + "ninety-nine percent perspiration.(Thomas Edison)").getBytes(); String hexEncoded = utils.hexEncode(bytes); System.out.println(hexEncoded); // Hex Decode String decoded = new String(utils.hexDecode(hexEncoded)); System.out.println(decoded);
