Hello

Checksum calculation is supported using ftps, but i am getting error ----> Operation not supported.
with the following line :

$remoteChecksum = [System.BitConverter]::ToString($session.CalculateFileChecksum($remoteChecksumAlg, $remotePath))

thanks

But only if the FTP server supports any of the HASH, XSHA1, XSHA256, XSHA512, MD5, XMD5 or XCRC commands. And your remoteChecksumAlg value (what is it?) matches the supported algorithm.

See https://winscp.net/eng/docs/protocols

Please attach a full session log file to confirm.

To generate log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Ok,
It may be not supported, but I share anyway my script with the whole log session .


SCRIPT:

Code:
param (
    $localPath = "E:\xxxx\IMGP1280.JPG",
    $remotePath = "/IMGP1280.JPG",
    $logfileName = $(Get-Date -f "dd-MM-yyyy"),
    $remoteChecksumAlg = "HASH"
)

    # Load WinSCP .NET assembly
    Add-Type -Path "C:\FTPSynch\winscp577automation\WinSCPnet.dll"

# Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::ftp
        FtpSecure = [WinSCP.FtpSecure]::Implicit
        HostName = "xxxx.xxxx-xxxx.net"
        UserName = "xxxx@xxxx.xxxx-fichiers.net"
        Password = "xxxx"
        PortNumber = "990"
        FtpMode = "Passive"
        TlsHostCertificateFingerprint = "xxxx"
    }
 
 
    $session = New-Object WinSCP.Session
    $session.SessionLogPath = "C:\FTPSynch\Log_files\winscpCHECKsum.log"

try
{
    Write-Host $localPath
 
    # Calculate local file checksum
    $sha1 = [System.Security.Cryptography.SHA1]::Create()
    $localStream = [System.IO.File]::OpenRead($localPath)
    $localChecksum = [System.BitConverter]::ToString($sha1.ComputeHash($localStream))
 
    Write-Host $localChecksum
 
    try
    {        $session.Open($sessionOptions)
        Write-Host $remotePath
 
        # Calculate remote file checksum
        $remoteChecksum = [System.BitConverter]::ToString($session.CalculateFileChecksum($remoteChecksumAlg, $remotePath))

        Write-Host $remoteChecksum
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
 
    # Compare cheksums
    if ($localChecksum -eq $remoteChecksum)
    {
        Write-Host "Match"
        $result = 0
    }
    else
    {
        Write-Host "Does NOT match"
        $result = 1
    }
}
catch [Exception]
{
    Write-Host $_.Exception.Message
    $result = 1
}
 
# Pause if -pause switch was used
if ($pause)
{
    Write-Host "Press any key to exit..."
    [System.Console]::ReadKey() | Out-Null
}
 
exit $result
