[quote="g0nz0uk"]Hello,

I need to encrypt my password in this copy script from Windows to Linux.  This script has been working fine, I just need to add security.

Current working code
[code]@powershell@
# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "192.168.138.113"
    UserName = "test"
    Password = "test999#"
    SshHostKeyFingerprint = "ssh-ed25519 255 mfVWm6kqrWMoPBy7q7tkZydM/SmvA3jVPjRXoLxcLfA="
}
$session = New-Object WinSCP.Session
try
{
    # Connect
    $session.Open($sessionOptions)
    # Transfer files
    $session.PutFiles("C:\dism.log", "/usr/share/csv/*").Check()
}
finally
{
    $session.Dispose()
}[/code]
I then tried to encrypt:
I ran this to generate the hashed password:
[code]@powershell@
Read-Host 'enter password' -AsSecureString |
ConvertFrom-SecureString |
Out-File 'C:\temp\password.txt'[/code]
Then added to my script:
[code]@powershell@

$sessionOptions = New-Object WinSCP.SessionOptions -Property @{

This really isn't working. Now I get:

ConvertTo-SecureString : Input string was not in a correct format.

What am I doing wrong here to encrypt my session?

I mean this:

    SecurePassword = ConvertTo-SecureString "01000000...
"

It should be:

    SecurePassword = ConvertTo-SecureString "01000000..."

I'm not sure what you mean. So my screenshot shows a " on a new line is that what you mean?

There should be no newline in the string literal:

SecurePassword = ConvertTo-SecureString "01000000d08c9ddf0115d1118c7a00c04fc297eb01000000f7e98d274da0e843a4ff48f5aa20208200000000020000000000106600000001000gkhkjhkjhkjhlkjlkj428a8b5d2fae4abd140000000ba8036948a049304e1311100b694fc03d1445d9d03ff0e25e0461383d303f9d9b5f76f477c514cf939c7637fd88897e32815af66e9ecefa8619e18e12202ac7c"

Struggling to encrypt the password in my WinSCP PowerShell script (example below)

2021-03-07 12:26

Hello,

I need to encrypt my password in this copy script from Windows to Linux. This script has been working fine, I just need to add security.

Current working code

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "192.168.138.113"
    UserName = "test"
    Password = "test999#"
    SshHostKeyFingerprint = "ssh-ed25519 255 mfVWm6kqrWMoPBy7q7tkZydM/SmvA3jVPjRXoLxcLfA="
}
$session = New-Object WinSCP.Session
try
{
    # Connect
    $session.Open($sessionOptions)
    # Transfer files
    $session.PutFiles("C:\dism.log", "/usr/share/csv/*").Check()
}
finally
{
    $session.Dispose()
}

I then tried to encrypt:
I ran this to generate the hashed password:

Read-Host 'enter password' -AsSecureString |
ConvertFrom-SecureString |
Out-File 'C:\temp\password.txt'

Then added to my script:

# Load WinSCP .NET assembly
Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
 
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "192.168.138.113"
    UserName = "test"
    SecurePassword = ConvertTo-SecureString "01000000d08c9ddf0115d1118c7a00c04fc297eb01000000f7e98d274da0e843a4ff48f5aa20208200000000020000000000106600000001000gkhkjhkjhkjhlkjlkj428a8b5d2fae4abd140000000ba8036948a049304e1311100b694fc03d1445d9d03ff0e25e0461383d303f9d9b5f76f477c514cf939c7637fd88897e32815af66e9ecefa8619e18e12202ac7c
"
   SshHostKeyFingerprint = "ssh-ed25519 255 mfVWm6kqrWMoPBy7q7tkZydM/SmvA3jVPjRXoLxcLfA="
}
 
$session = New-Object WinSCP.Session
 
try
{
    # Connect
    $session.Open($sessionOptions)
 
    # Transfer files
    $session.PutFiles("C:\dism.log", "/usr/share/csv/*").Check()
}
finally
{
    $session.Dispose()
}

But get this error when running:

ConvertTo-SecureString : Input string was not in a correct format.

At line:9 char:22

+ ... ePassword = ConvertTo-SecureString "01000000d08c9ddf0115d1118c7a00c04 ...

Any idea I what I need to add/change?
