Perl AES vs Ruby AES - ruby

Question

I cannot get Perl and Ruby to agree on CBC AES:
Perl
use Crypt::CBC;
use MIME::Base64::Perl;
my $cipher = Crypt::CBC->new(
-key => 'd2cb415e067c7b13',
-iv => 'e36dc751d0433f05', #random 16chars!!!!!! shold NOT repeat between requests
-cipher => 'OpenSSL::AES', #this is same as Rijndael
-literal_key => 1,
-header => "none",
-keysize => 16
);
$encypted = $cipher->encrypt("a really really long long text has differrent results???");
$base64 = encode_base64($encypted);
print("Ciphertext(b64): $base64");
$de_base64 = decode_base64($base64);
$decrypted = $cipher->decrypt($de_base64);
$c = $cipher->finish;
Ciphertext(b64): qz4eSQaFkQUkDOyJSbZf5W03HoldwtgvTLq0yJFRViKJnytf3PVSCGW2CYDjO+tRqV20oxeB2VPa
7NqN1TDSNQ==
there's a newline after the 2VPa section and another at the end
Ruby
require 'openssl'
require 'digest/sha2'
require 'base64'
message = "a really really long long text has differrent results???"
cipher = OpenSSL::Cipher.new('aes-128-cbc')
# digest the key, iv and hmac_key so we have 16-byte length
# also, it looks more of a funky password
# prepare cipher
cipher.encrypt
cipher.key = aes_key = "d2cb415e067c7b13"
cipher.iv = aes_iv = "e36dc751d0433f05"
encrypted = cipher.update(message)
encrypted << cipher.final()
b64_encoded = Base64.encode64(encrypted).encode('utf-8') #strict_encode64 guarantees no newlines, encode64 is default
puts "AES Key : '#{aes_key}'"
puts "AES IV : '#{aes_iv}'"
puts "Ciphertext(b64): '#{b64_encoded}'"
Ciphertext(b64): 'qz4eSQaFkQUkDOyJSbZf5W03HoldwtgvTLq0yJFRViKJnytf3PVSCGW2CYDj
O+tRqV20oxeB2VPa7NqN1TDSNQ==
'
Note the newlines chars after CYDj and after ==
I've seen the following: Perl & Ruby exchange AES encrypted information, but I'm not using padding=0

Answer 1

Newlines are not significant in Base64. You got exactly the same result from both languages.
While there should be absolutely no reason to do so, you could make the Perl version return the same string as the Ruby version as follows:
$base64 = encode_base64($encypted, '');
$base64 =~ s/\G.{60}\K/\n/sg;

Answer 2

The encode_base64 function takes a second parameter, called "eol" (end of line) which, by default, is '\n'.
The returned encoded string is broken into lines of no more than 76
characters each and it will end with $eol unless it is empty
Try:
$base64 = encode_base64($encypted, '');
instead.
