What WinSCP does
WinSCP is a GPL-licensed Windows file-transfer client supporting SFTP and SCP over SSH, FTP, FTPS, WebDAV/WebDAVS, and Amazon S3. Protocol names are not interchangeable security guarantees: plain FTP and WebDAV do not encrypt transport, while SSH- and TLS-based modes still depend on correct host-key or certificate verification, algorithms, credentials, and server configuration. S3 interoperability beyond Amazon's service depends on the endpoint's compatibility.
The desktop client provides Commander and Explorer layouts, transfers, queueing, directory comparison and synchronization, remote editing, session profiles, and scripting. Synchronization and automation can overwrite or delete data when direction, criteria, masks, or destination paths are wrong; review planned operations, use least-privilege server credentials, and keep recoverable backups. Remote editing downloads a temporary copy and uploads changes rather than editing a server file in place.
This record retains WinSCP 6.5.6 from the stable release line: the interactive Setup EXE, managed-deployment MSI, and portable ZIP. These stable packages use WinSCP's regular 32-bit application build, which runs on compatible 64-bit Windows; experimental native 64-bit packages belong to a different prerelease line. The MSI installs the complete product without the Setup program's component choices. The portable ZIP contains GUI and console executables, but portability is configuration-dependent: it normally uses an INI file when writable, while random-seed, temporary-file, or fallback settings can still touch the host profile or temp locations. Installed WinSCP defaults to the current user's registry.
The SHA-256 values below are published on WinSCP's version-specific download pages. WinSCP also documents Authenticode signing, but this audit did not run the binaries or validate their signatures. First-use SSH host keys should be compared through a trusted channel; accepting an unknown fingerprint without verification permits a man-in-the-middle risk. Saved passwords without a master password are recoverable and are not equivalent to a protected credential vault. No WinSCP account is required, but transfers need reachable servers and their credentials, while update checks require connectivity. Portable and MSI packages do not support WinSCP's automatic update installation.
