Hello I'm making a a form that create a user with username and password and then crypts the data and store it in database ; password crypting is working fine i think but stores the name as CGI::Simple=HASH(0x55bb333591e0). Here is the code for creating the user: 
#!/usr/bin/perl
use strict;
use warnings;
use DBI;
use CGI::Simple;
use Crypt::Argon2 qw/argon2id_pass argon2id_verify/;
sub user_crypt;sub createUser;

sub user_crypt {
 my ($cryUser , $cryPass)=@_;
my $salt = rand(16);
my $encode = argon2id_pass($cryPass,$salt,3,'32M',1,16);
createUser($cryUser,$encode);
}


sub createUser{
my ($user , $hashPass)=@_;
my $statement="INSERT INTO LOGIN_DATA(USER_NAME,USER_HASH) VALUES(?,?)
+";
my $driver="mysql";
my $database="USERS";
my $dsn="DBI:$driver:database=$database";
my $databaseUser="root";
my $databasePass="";
my $dbcon= DBI->connect($dsn,$databaseUser,$databasePass) or die $!;
my $preState = $dbcon->prepare($statement) ;
$preState->execute($user , $hashPass) or die $!;

}

my $username=CGI::Simple->new;
my $pass=CGI::Simple->new;
$username->param('textfield');
$pass->param('pass');

user_crypt($username,$pass);

print "Content-type: text/html\n\n";
print "<html><body>\n";
print "<h1>Random heading</h1>\n";
print "$username , $pass";
print "</body></html>\n";

and this is how is stored in the database 
CGI::Simple=HASH(0x55bb333591e0) | $argon2id$v=19$m=32768,t=3,p=1$MTMu

and after the program that verifies but of course it's not working because don`t know how to fetch the username . 
#!/usr/bin/perl
use strict;
use warnings;
use Crypt::Argon2 qw/argon2id_pass argon2id_verify/;
use DBI;
sub get_data; sub chec_pass;
sub get_data{
my ($user , $hash_pass);
my $statement = "SELECT * FROM LOGIN_DATA";
my $driver = "mysql";
my $database = "USERS";
my $dsn = "DBI:$driver:database=$database";
my $dataUsr = "root";
my $dataPass = "";
my $dbcon = DBI->connect($dsn,$dataUsr,$dataPass) or die  $!;
my $preState = $dbcon->prepare($statement);
$preState->execute();
my @row;
while (@row = $preState->fetchrow_array())
{
 
}
}
sub chec_pass {
my ($user, $password) = @_;
my $encoded = fetch_encoded($user);
return argon2id_verify($encoded  , $password);

}
