Utils Class

Properties Methods Events Config Settings Errors

The Utils class offers a selection of popular helper methods that may be of use in a variety of scenarios.

Syntax

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);

Fields

ContentDescription
char*
Default Value: ""

Provides a description for the part (Content-Description header field)

ContentDisposition
char*
Default Value: ""

Specifies the disposition of the part (Content-Disposition header field)

ContentID
char*
Default Value: ""

Specifies the ID of the part (Content-ID header field)

This property allows to check or set the category (or type) associated with the contained value. Depending on the format used to load or save the string, the category parameter may or may not be used.

For example, for ASN.1 property lists the category contains the ASN.1 tag of the contained data (OCTETSTRING, UTF8STRING, INTEGER, ...). For basic (name, value) pairs, such as HTTP headers, the category parameter is not used.

Format
int
Default Value: 0

Specifies the format (encoding) of the value contained in the Value property.

Use this property to check or set the format of the contained value. Remember to provide the actual value in the appropriate format that matches this setting: utils.NameValuePairs[0].Name = "key"; utils.NameValuePairs[0].Format = svfBinary; utils.NameValuePairs[0].Name = "0a1b2c3d4e5f6071";

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the Utils class.

Methods

GetCount	This method returns the current size of the collection. int GetCount() {}
SetCount	This method sets the size of the collection. This method returns `0` if setting the size was successful; or `-1` if the collection is `ReadOnly`. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. int SetCount(int count) {}
Get	This method gets the item at the specified position. The `index` parameter specifies the index of the item in the collection. This method returns `NULL` if an invalid `index` is specified. T* Get(int index) {}
Set	This method sets the item at the specified position. The `index` parameter specifies the index of the item in the collection that is being set. This method returns `-1` if an invalid `index` is specified. Note: Objects created using the `new` operator must be freed using the `delete` operator; they will not be automatically freed by the class. T* Set(int index, T* value) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The Utils class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the Utils class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead	Whether the stream supports reading. bool CanRead() { return true; }
CanSeek	Whether the stream supports seeking. bool CanSeek() { return true; }
CanWrite	Whether the stream supports writing. bool CanWrite() { return true; }
Length	Gets the length of the stream, in bytes. int64 GetLength() = 0;
Methods

Close	Closes the stream, releasing all resources currently allocated for it. void Close() {} This method is called automatically when a SecureBlackboxStream object is deleted.
Flush	Forces all data held by the stream's buffers to be written out to storage. int Flush() { return 0; } Must return `0` if flushing is successful; or `-1` if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return `0`.
Read	Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read. int Read(void* buffer, int count) = 0; `Buffer` specifies the buffer to populate with data from the stream. `Count` specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into `Buffer`; this may be less than `Count` if that many bytes are not currently available, or `0` if the end of the stream has been reached. Must return `-1` if an error occurs, if reading is not supported, or if the stream is closed.
Seek	Sets the current position within the stream based on a particular point of origin. int64 Seek(int64 offset, int seekOrigin) = 0; `Offset` specifies the offset in the stream to seek to, relative to `SeekOrigin`. Valid values for `SeekOrigin` are: `0`: Seek from beginning. `1`: Seek from current position. `2`: Seek from end. Must return the new position within the stream; or `-1` if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If `-1` is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an `Offset` of `0` and a `SeekOrigin` of `1` to obtain the current position within the stream, even if seeking is not otherwise supported.
Write	Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written. int Write(const void* buffer, int count) = 0; `Buffer` specifies the buffer with data to write to the stream. `Count` specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than `Count` if that many bytes could not be written. Must return `-1` if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (Utils Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

Utils Config Settings

MaxInMemoryPartSize: The maximal size of a message part to keep in memory.

If the message part exceeds this size (which is set to 100KB by default), a temporary file will be created to keep it.

MultipartBoundary: Returns the boundary string used to save the last multipart message.

MultipartCharset: Specifies the charset to be used to encode the field names and the filenames of the multipart message.

RelatedStart: Identifies the starting body part or root.

Provides the starting body part or root for multipart messages transferred over HTTP.

RelatedStartInfo: Contains additional information required for unpacking or processing of the content.

Provides additional information for unpacking or processing of the content in multipart messages transferred over HTTP.

RelatedType: Contains media type/subtype of message's content.

Provides the media type/subtype of message's content in multipart messages transferred over HTTP.

TempPath: Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

Base Config Settings

ASN1UseGlobalTagCache: Controls whether ASN.1 module should use a global object cache.

This is a performance setting. It is unlikely that you will ever need to adjust it.

AssignSystemSmartCardPins: Specifies whether CSP-level PINs should be assigned to CNG keys.

This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

CheckKeyIntegrityBeforeUse: Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching: Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:


off		No caching (default)
local		Local caching
global		Global caching

Cookies: Gets or sets local cookies for the class.

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

DNSLocalSuffix: The suffix to assign for TLD names.

Use this global setting to adjust the default suffix to assign to top-level domain names. The default is .local.

EnableClientSideSSLFFDHE: Enables or disables finite field DHE key exchange support in TLS clients.

debug		Detailed information on flow of through the system.
trace		More detailed information.

LogMaxEventCount: Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

OldClientSideRSAFallback: Specifies whether the SSH client should use a SHA1 fallback.

Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

ProductVersion: Returns the version of the SecureBlackbox library.

This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

ServerSSLDHKeyLength: Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

StaticDNS: Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:

StaticIPAddress[domain]: Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses: Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag: Allows to store any custom data.

Use this config property to store any custom data.

UseOwnDNSResolver: Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemNativeSizeCalculation: An internal CryptoAPI access tweak.

This is an internal setting. Please do not use it unless instructed by the support team.

UseSystemOAEPAndPSS: Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom: Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

Trappable Errors (Utils Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
