I have integrated NET:SFTP module and trying test the "sftp put" fuctionality.

put($lclfile, "$remfile");

Occasionally I get this error "input must be 8 bytes long at DES.pm line 58.".

When I execute the same command next time the sftp put works fine. Any clue?

More precisely I get this error first time after SFTP setup.After exchanging the keys. Please help..

Hi arul, Have you resolved this issue yet? I also encountered this problem when using Net-SFTP. i It seems wired and I can't find the exactly solution to it. -Leo

Possible culprit could be encoding. Your input has to have characters 8 byte long. If it's in e.g. utf8, change it this way: from_to ($input,'utf8','iso-8859-1') where from_to must be imported from Encode module. Radek

I was having the same problem when sending a User Password that was taken from the command line. The following code worked for me:

use utf8;
# .. MORE CODE HERE .. 
# GET USER PASSWORD
print "\nPassword for $UserName\n";
system('stty', '-echo') == 0 or die "can't turn off echo: $?";
my $UserPassword = <STDIN>;
system('stty', 'echo') == 0 or die "can't turn on echo: $?";
chomp $UserPassword; # Remove newline character
# Convert to utf8 to avoid problem with DES.pm module
utf8::encode ($UserPassword);

# THE SFTP CONNECTION THEN WORKS AS
$sftp = Net::SFTP->new(
    $IndTarget,
    user=> $UserName,
    password=> $UserPassword,
    debug=>"true",
);
