It looks like the encryption is getting closer, but not exact. From my php encrypted string, they always end in %3D. My perl encrytped string is slightly longer and ends in ...%3D%0A. 

#!/usr/bin/perl

use Crypt::CBC;
use Crypt::Rijndael;
use Digest::MD5 qw(md5_hex md5_base64);
use MIME::Base64;
use URI::Escape;

sub encrypt{
    my $data = shift;
    $data = &get16($data);
    my $key = "HELLOKEY";
    my $key_size = 16;
    my $key_hash = md5_hex($key);
    $AESKEY = substr($key_hash,0,$key_size);
    print "AESKEY->".$AESKEY."\n";
    my $iv= Crypt::CBC->random_bytes(16);
    my $cipher = Crypt::CBC->new(
                 -key    =>  $AESKEY,
                 -cipher => 'Rijndael',
                 -padding => 'rijndael_compat',
                 -keysize => $keysize,
                 -header => 'none',
                 -iv =>$iv
                 );
    
    $iv = $cipher->get_initialization_vector();  
    my $encrypted = $cipher->encrypt($data);
    print "After encryption:$encrypted\n";
    $encrypted = $iv.$encrypted;
    $encrypted = encode_base64($encrypted);
    print "After base 64 encoding:$encrypted\n\n";    
    
    $encrypted =  uri_escape($encrypted);
    print "After url_encoding: $encrypted\n";
}

&encrypt("test123");
