KeySize error occurred during the installation of VHCS control panel

Add the following entry in 1887th line of /var/lib/dpkg/info/vhcs.postinst.

keysize => 32,

You need to enter this value before "key => " part.

After this modification run the script:

/var/www/vhcs2/engine/vhcs2-rqst-mngr

You will get another error message saying:

 If specified by -literal_key, then the key length must be equal to the chosen cipher’s key length of 56 bytes at /var/www/vhcs2/engine//vhcs2_common_code.pl line 1443 Compilation failed in require at ./var/www/vhcs2/engine/vhcs2-rqst-mngr line 33. 

You need to add an entry in 1441-th line of /var/www/vhcs2/engine/vhcs2_common_code.pl to fix this issue

modify following code:

my $cipher = Crypt::CBC -> new(
{
‘key’ => $main::db_pass_key,
‘cipher’ => ‘Blowfish’,
‘iv’ => $main::db_pass_iv,
‘regenerate_key’ => 0,
‘padding’ => ’space’,
‘prepend_iv’ => 0
}
);

to

my $cipher = Crypt::CBC -> new(
{
‘keysize’ => 32,
‘key’ => $main::db_pass_key,
‘cipher’ => ‘Blowfish’,
‘iv’ => $main::db_pass_iv,
‘regenerate_key’ => 0,
‘padding’ => ’space’,
‘prepend_iv’ => 0
}
);

This will fix the issue.
