Object Oriented Interface


public function getExternalCryptoKeyID();


public function setExternalCryptoKeyID($value);

Procedural Interface


secureblackbox_sftpserver_get($res, 30 );


secureblackbox_sftpserver_set($res, 30, $value );

Default Value

''

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 25, array($this, 'fireExternalSign'));

Parameter List

 'connectionid'
'operationid'
'hashalgorithm'
'pars'
'data'
'signeddata'

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

ostInvalidParameter6
ostEOF7

FindFirst Event (SecureBlackbox_SFTPServer Class)

This event signifies the start of the custom file listing retrieval mechanism.

Object Oriented Interface

public function fireFindFirst($param);

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 27, array($this, 'fireFindFirst'));

Parameter List

 'connectionid'
'path'
'operationstatus'
'handle'

Remarks

FindFirst, FindNext, and FindClose events represent a mechanism for providing customized file listings to class. They are only fired if Action parameter of the preceding BeforeFind event was set to fraCustom.

The behaviour of these events mimics that of the standard FindFirst/FindNext/FindClose functions found in many operating systems/frameworks. FindFirst fires once to request the first list entry; FindNext then fires continuously in a loop to request all subsequent entries. To indicate that the listing is over, set OperationStatus parameter to ostEOF. Not doing so may lead to an endless loop and session freeze, as the component would continue firing FindNext infinitely waiting for the EOF marker.

The handlers for both FindFirst and FindNext events should be implemented in the following way: if there are more entries in the directory to pass back to the server component,

  • set OperationStatus to ostOK,
  • fill in ClientFileEntry with the details of the next entry,
  • commit the entry to the server using SetClientFileEntry method.
When all the entries from the requested directory have been passed to the server component, set OperationStatus to ostEOF. The server will then fire FindClose event to notify your code that the file listing is completed.

Use the by-ref Handle parameter to assign a handle (a unique identifier) to the file listing procedure inside the FindFirst event handler. This identifier will then be passed to all subsequent FindNext and FindClose calls to let your code chain the events together.

The ConnectionID parameter specifies in which SFTP session the request was received, and Path indicates the requested directory.

The following operation status constants are available, besides the ones referenced above:

ostOk1
ostNoSuchFile2
ostAccessDenied3
ostWriteProtect4
ostUnsupported5
ostInvalidParameter6
ostEOF7

FindNext Event (SecureBlackbox_SFTPServer Class)

'operationstatus'

Remarks

This event is fired repeatedly after FindFirst to retrieve the directory contents entry-by-entry. Please see the FindFirst topic for more details about implementing a handler of this event.

Remember to set OperationStatus to ostEOF when there are no more entries left to close the listing operation. If there are more entries to pass, set it to ostOK. Other possible values are given in the table below:

ostOk1
ostNoSuchFile2
ostAccessDenied3
ostWriteProtect4
ostUnsupported5
ostInvalidParameter6
ostEOF7

Notification Event (SecureBlackbox_SFTPServer Class)

public function fireNotification($param);

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 29, array($this, 'fireNotification'));

Parameter List

 'eventid'
'eventparam'

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

This class can fire this event with the following EventID values:

FileOpenNotifies your code about the file being opened, which is typically an indicator of the initiation of the transfer operation. The EventParam value passed with this EventID is a string of the following format:

ConnectionID=3;Path=/dir/file;Handle=x5DshAk8;Modes=48;Access=0;DesiredAccess=8

This EventID only fires if the NotifyOnFileOperations configuration property is set to true.

FileReadNotifies your code about the file chunk being requested. The EventParam value passed with this EventID is a string of the following format:

ConnectionID=7;Handle=x5DshAk8;Offset=2048;Count=1024;Read=1021

This EventID only fires if the NotifyOnFileOperations configuration property is set to true.

FileWriteNotifies your code about the file chunk being received. The EventParam value passed with this EventID is a string of the following format:

ConnectionID=7;Handle=x5DshAk8;Offset=2048;Count=1024

This EventID only fires if the NotifyOnFileOperations configuration property is set to true.

FileCloseNotifies your code about the closure of an opened file. The EventParam value passed with this EventID is a string of the following format:

ConnectionID=7;Handle=x5DshAk8;Modes=48

This EventID only fires if the NotifyOnFileOperations configuration property is set to true.

OpenShellNotifies your code about an opened shell tunnel. The EventParam has the following format: ConnectionID=9;LocalChannel=1;RemoteChannel=2
OpenCommandNotifies your code about an opened command tunnel. The EventParam value has the following format:

ConnectionID=8;LocalChannel=3;RemoteChannel=3;Command=ls -l

OpenFile Event (SecureBlackbox_SFTPServer Class)

This event instructs the application to handle the file open request.

Object Oriented Interface

public function fireOpenFile($param);

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 30, array($this, 'fireOpenFile'));

Parameter List

 'connectionid'
'path'
'modes'
'access'
'operationstatus'
'handle'

Remarks

This event is fired when a file open request is received from the client and needs to be handled (virtualized) by the server. The ConnectionID parameter specifies in which session the request was received, and Path specifies the location of the file.

Modes can be a combination of one or several file open mode flags:

cfmRead1
cfmWrite2
cfmAppend4
cfmCreate8
cfmTruncate16
cfmExcl32
cfmText64
cfmOpenOrCreate128
cfmAppendAtomic256
cfmNoFollow512
cfmDeleteOnClose1024

Different client applications may provide different selections of mode flags. For example, some clients specify (cfmCreate + cfmTruncate) when overwriting files, whereas others would specify cfmOpenOrCreate. Please make sure your code is prepared to receive different combinations of flags here and handles them gracefully.

The Access parameter provides additional file access modifiers:

cfaReadLock1
cfaWriteLock2
cfaDeleteLock4
cfaBlockAdvisory8
These parameter may also contain a combination of the above flags. Access modifiers are only supported in SFTPv6, and in practice are rarely used by client applications.

The Handle string represents a unique identifier of the opened file, similar to file handles used in Windows or Unix APIs. Handles are unique across all files opened at the same time. Class generates handles automatically, but you can update the auto-generated values with your own in this event handler (just remember to keep them unique).

Config Settings (SFTPServer 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.

SFTPServer Config Settings

AuthMode:   Controls dual/multi-type authentication mode.

Use this setting to adjust dual/multi-step authentication mode. The value of 0 indicates that either of supported authentication methods is sufficient to authenticate the user ("any of"). The value of 1 specifies that the user should pass all the enabled methods to authenticate themselves (MFA, or "all of").

CustomDHGroupIndex:   Sets a specific Diffie-Hellman group index to enforce.

Use this property to specify a specific DH group index to enforce for key exchange. The value of -1 enables automatic group selection, and any value between 0 and 227 specifies a particular DH group supported by SecureBlackbox. This is largely a debug setting, use it with extreme care.

DualStack:   Allows the use of ip4 and ip6 simultaneously.

This setting specifies a socket can use ip4 and ip6 simultaneously.

MaxDHGroupSize:   Sets the maximal Diffie-Hellman group size.

This property specifies the maximal DH group size, in bits. The larger the group size, the strong the key, however, longer groups put extra burden on the computational resources. SecureBlackbox supports groups between 1024 and 8192 bits. The default value is 8192.

MinDHGroupSize:   Sets the minimal Diffie-Hellman group size.

This property specifies the minimal DH group size, in bits. The larger the group size, the strong the key, however, longer groups put extra burden on the computational resources. SecureBlackbox supports groups between 1024 and 8192 bits. The default value is 2048.

NotifyOnFileOperations:   Enables low-level file operation notifications.

If set, the component will report low-level file operations, such as Open, Read, Write, and Close, via its Notification event.

UseStrictKeyExchange:   Specifies how strict key exchange is supported.

This setting controls whether strict key exchange (strict kex) is enabled to mitigate the Terrapin attack. When enabled, the class will indicate support for strict key exchange by automatically including the pseudo-algorithm kex-strict-c-v00@openssh.com for client classes and kex-strict-s-v00@openssh.com for server classes in the list of supported key exchange algorithms.

Since both client and server must implement strict key exchange to effectively mitigate the Terrapin attack, the class provides options to further control the behavior in different scenarios. Possible values for this setting are:

0Disabled. Strict key exchange is not supported in the class.
1 (default)Enabled, but not enforced. This setting enables strict key exchange, but if the remote host does not support strict key exchange the connection is still allowed to continue.
2Enabled, but reject affected algorithms if the remote host does not support strict key exchange. If the remote host supports strict key exchange all algorithms may be used. If the remote host does not support strict key exchange the connection will only continue if the selected encryption and MAC algorithms are not affected by the Terrapin attack.
3Required. If the remote host does not support strict key exchange the connection will fail.

Base Config Settings

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:

offNo caching (default)
localLocal caching
globalGlobal 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.

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

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile
consoleConsole
systemlogSystem Log (supported for Android only)
debuggerDebugger (supported for VCL for Windows and .Net)

LogDetails:   Specifies the debug log details to dump.

Contains a comma-separated list of values that specifies which debug log details to dump.

Supported values are:

timeCurrent time
levelLevel
packagePackage name

LogFilters:   Specifies the debug log filters.

Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore 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.

LogRotationMode:   Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

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.

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:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

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.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

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.

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.
