FTPServer Class

Properties   Methods   Events   Configuration Settings   Errors  

The FTPServer class provides server-side functionality for FTP and FTPS protocols.

Syntax

secureblackbox.Ftpserver

Remarks

FTPServer supports FTP (File Transfer Protocol) and FTPS (FTP-over-SSL) protocols. The FTPS protocol allows you to securely perform file transfer operations on the server over Transport Layer Security (TLS). TLS is a successor to the now deprecated SSL protocol, although the latter abbreviation is still widely used.

public Certificate();

Creates a new object with default field values.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

AsyncDocumentID
String

Specifies the document ID for SignAsyncEnd() call

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. This value helps ASiCSigner identify the correct signature in the returned batch of responses. If using batched requests, make sure to set this property to the same value on both pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
String

Custom parameters to be passed to the signing service (uninterpreted).

Data
String

Additional data to be included in the async state and mirrored back by the requestor

ExternalHashCalculation
boolean

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by all components. In particular, components operating with larger objects (PDFSigner, CAdESSigner, XAdESSigner) do not support it.

HashAlgorithm
String

Specifies the request's signature hash algorithm.

KeyID
String

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 extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret 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";

KeySecret
String

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the KeyID topic.

Method
int

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

Available options:

asmdPKCS10
asmdPKCS71

Mode
int

Specifies the external cryptography mode.

Available options:

ecmDefaultThe default value (0)
ecmDisabledDo not use DC or external signing (1)
ecmGenericGeneric external signing with OnExternalSign event (2)
ecmDCAuthDCAuth signing (3)
ecmDCAuthJSONDCAuth signing in JSON format (4)

PublicKeyAlgorithm
String

Provide public key algorithm here if the certificate is not available on the pre-signing stage.

String

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
boolean

Whether to force TLS session resumption when the destination address changes.

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
int

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

crcNone (0)No revocation checking
crcAuto (1)Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL (2)Check all provided CRL endpoints for all chain certificates.
crcAllOCSP (3)Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP (4)Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL (5)At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP (6)At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP (7)At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL (8)At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Configuration Settings (Ftpserver 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.

FTPServer Configuration Settings

ActiveChannel:   The channel to which the event that is being invoked corresponds.

Use this property to find out which channel, command or data, has invoked the current event. This property returns reliable values and should only be checked while inside an event handler. facCmd = 0; facData = 1;

ClientAuth:   Enables or disables certificate-based client authentication.

Set this property to true to tune up the client authentication type: ccatNoAuth = 0; ccatRequestCert = 1; ccatRequireCert = 2;

DualStack:   Allows the use of IPv4 and IPv6 simultaneously.

This setting specifies a socket can use IPv4 and IPv6 simultaneously.

RefreshUsers:   Enables or disables real-time propagation of user information.

Set this property to true to make the content of the Users property propagate to the server immediately. The default setting is false, which delays the effect of any changes in the Users setting until the server is restarted.

Base Configuration 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 (supported for HTTPClient, RESTClient and SOAPClient only)
globalGlobal caching

Cookies:   Gets or sets local cookies for the class (supported for HTTPClient, RESTClient and SOAPClient only).

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
moduleModule name
classClass name
methodMethod name
threadidThread Id
contenttypeContent type
contentContent
allAll details

LogFile:   Specifies the debug log filename.

Use this property to provide a path to the log file.

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.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

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.
