ExternalSign Event (SFTPServer Module)
Handles remote or external signing initiated by the server protocol.
Syntax
func onExternalSign(connectionID: Int64, operationId: String, hashAlgorithm: String, pars: String, data: String, signedData: inout String)
- (void)onExternalSign:(long long)connectionID :(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)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();
};

See FindFirst topic for the details on implementing customized file listing request processing.
Set OperationStatus to one of the below values according to the outcome of the request processing:
ostOk | 1 | |
ostNoSuchFile | 2 | |
ostAccessDenied | 3 | |
ostWriteProtect | 4 | |
ostUnsupported | 5 | |

FindFirst Event (SFTPServer Module)
This event signifies the start of the custom file listing retrieval mechanism.
Syntax
func onFindFirst(connectionID: Int64, path: String, operationStatus: inout Int32, handle: inout String)
- (void)onFindFirst:(long long)connectionID :(NSString*)path :(int*)operationStatus :(NSString**)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.
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:
ostOk | 1 | |
ostNoSuchFile | 2 | |
ostAccessDenied | 3 | |
ostWriteProtect | 4 | |
ostUnsupported | 5 | |
ostInvalidParameter | 6 | |
ostEOF | 7 |

Syntax
func onFindNext(connectionID: Int64, handle: String, operationStatus: inout Int32)
- (void)onFindNext:(long long)connectionID :(NSString*)handle :(int*)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:
ostOk | 1 | |
ostNoSuchFile | 2 | |
ostAccessDenied | 3 | |
ostWriteProtect | 4 | |
ostUnsupported | 5 | |

If using batched requests, make sure to set this property to the same value on both the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.
customParams
String
Default Value: ""
Custom parameters to be passed to the signing service (uninterpreted).
data
String
Default Value: ""
Additional data to be included in the async state and mirrored back by the requestor.
externalHashCalculation
Bool
Default Value: False
Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth class.
If set to true, the class will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

keyID
String
Default Value: ""
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 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
Default Value: ""
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.

Specifies the maximal time for the SSH handshake to proceed, in seconds. If the handshake is not completed within this period, the session is aborted.
kexAlgorithms
String
Default Value: ""
A list of key exchange algorithms separated with commas or semicolons. Each algorithm in the list may be prefixed with a minus sign (-) to indicate that the algorithm should be disabled rather than enabled. Besides the specific algorithm names, this property supports the all (and -all) aliases that allow to blanketly enable or disable all key exchange algorithms at once.
Note: the list of algorithms provided to this property alters the baseline list of key exchange algorithms pre-configured for this component. Remember to start your algorithm string with -all; if you need to only enable a specific fixed set of algorithms. The list of supported kex algorithms is provided below:

Remarks
UserAccount objects are used to store user account information, such as logins and passwords.
Fields
associatedData
Data
Default Value: ""

Default Value: 0
Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.
When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object
after such operation.
pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
hashAlgorithm

otpAlgorithm
OTPAlgorithms
Default Value: 0
The algorithm used to generate one-time passwords (OTP) for this user, either HOTP (Hash-based OTP) or TOTP (Time-based OTP). In the former case, a value of a dedicated counter is used to generate a unique password, while in the latter the password is generated on the basis of the current time value.

Default Value: ""
Contains the user's SSH key.
username
String
Default Value: ""
The registered name (login) of the user.
Constructors
public init()
Creates a new UserAccount object
Config Settings (SFTPServer Module)
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
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:
0 | Disabled. 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. |
2 | Enabled, 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. |
3 | Required. If the remote host does not support strict key exchange the connection will fail. |
Base Config Settings
You can switch this property off to improve performance if your project only uses known, good private keys.
