Properties

Procedures

• AddFingerprintSHA256(Fingerprint: Text): Adds a SHA256 fingerprint to the list of accepted host key fingerprints.
• AddFingerprintMD5(Fingerprint: Text) Δ BC29 (obsolete 29.0: MD5 host key fingerprints are cryptographically insecure and are no longer supported. Use AddFingerprintSHA256 instead.): Obsolete. MD5 host key fingerprints are cryptographically insecure and are no longer supported. Calling this method always raises an error. Use AddFingerprintSHA256 instead.
• Initialize(Hostname: Text; Port: Integer; Username: Text; Password: SecretText): Codeunit "SFTP Operation Response" Δ BC29 Δ BC29 Δ BC29: Initializes the SFTP client with the specified parameters. The client is connected to the server.
• Initialize(HostName: Text; Port: Integer; Username: Text; PrivateKey: InStream): Codeunit "SFTP Operation Response" Δ BC29 Δ BC29 Δ BC29: Initializes the SFTP client with the specified parameters. The client is connected to the server. The private key is used for authentication.
• Initialize(HostName: Text; Port: Integer; Username: Text; PrivateKey: InStream; Passphrase: SecretText): Codeunit "SFTP Operation Response" Δ BC29 Δ BC29 Δ BC29: Initializes the SFTP client with the specified parameters. The client is connected to the server. The private key is used for authentication and a passphrase is required to decrypt the private key.
• ListFiles(Path: Text; var FileList: List of [Interface "ISFTP File"]): Codeunit "SFTP Operation Response": Lists the files in the specified path on the SFTP server. The result is returned as a list of SFTP File interfaces.
• ListFiles(Path: Text; var FileList: Record "SFTP Folder Content"): Codeunit "SFTP Operation Response": Lists the files in the specified path on the SFTP server. The result is returned as a record of type “SFTP Folder Content”.
• GetFileAsStream(Path: Text; var InStream: InStream): Codeunit "SFTP Operation Response" Δ BC29: Downloads a file from the SFTP server and returns it as an InStream.
• DeleteFile(Path: Text): Codeunit "SFTP Operation Response": Deletes a file on the SFTP server.
• FileExists(Path: Text; var Result: Boolean): Codeunit "SFTP Operation Response": Tests if a file exists on the SFTP server.
• MoveFile(SourcePath: Text; DestinationPath: Text): Codeunit "SFTP Operation Response": Moves a file from one path to another on the SFTP server.
• Disconnect(): Disconnects the SFTP client from the server. This method should be called when the client is no longer needed.
• PutFileStream(Path: Text; var SourceInStream: InStream): Codeunit "SFTP Operation Response" Δ BC29: Uploads a file to the SFTP server from an InStream.
• GetWorkingDirectory(var Result: Text): Codeunit "SFTP Operation Response": Returns the working directory of the SFTP client. This is the directory that the client is currently working in.
• SetWorkingDirectory(Path: Text): Codeunit "SFTP Operation Response": Sets the working directory of the SFTP client. This is the directory that the client will work in for subsequent operations.
• IsConnected(): Boolean: Checks if the SFTP client is connected to the server. This method can be used to verify the connection status before performing operations.
• CreateDirectory(Path: Text): Codeunit "SFTP Operation Response": Creates a new directory on the SFTP server.

Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an Object::"Name" argument. Interface dispatch and calls through events are not counted, so the list is not complete.

• Codeunit 9763 “SFTP Client Implementation” (13 calls: AddFingerprintSHA256 → AddFingerPrintSHA256, CreateDirectory → CreateDirectory, DeleteFile → DeleteFile, …)

Recent changes

Deprecations

• procedure AddFingerprintMD5: Pending 29.0 (#if not CLEAN29), “MD5 host key fingerprints are cryptographically insecure and are no longer supported. Use AddFingerprintSHA256 instead.”

Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: bcatlas_resolve_node(object_type: "codeunit", object_name: "SFTP Client"), then bcatlas_get_procedure_body or bcatlas_get_neighbors on the returned id.
