如何在Ruby中执行3DES加密？

Question

I have a legacy Yii PHP system that is performing 3DES Encryption.

$data = 'id=1,username=admin,email=[e-mail]';
$encrypted_key = mhash(MHASH_SHA1,"foo_bar_key");
$encrypted_value = $StringHelper::encrypt($data, $encrypted_key); 
echo $encrypted_value 
//output => "0G8ITzc32wvqpDIjt6O7tZV9VKwU8KK7p0xI%2Fa%2FjiPOR%2FLrpfvsfMg9fyV2vAHgf"

I'm trying to get this same encrypted value in Ruby using 3DES encryption but I am not able to get it.

require 'openssl'
require 'mhash'
require 'base64'

@data = "id=1,username=admin,email=[e-mail]"
@encrypted_key = Mhash.sha1("foo_bar_key")

cipher = OpenSSL::Cipher::Cipher.new('des-ede-cbc')
cipher.encrypt
cipher.key = @encrypted_key
output = cipher.update(@data)

puts output 
# output => "\xFC\xCAR\xE2L\xB1\x1A\xCA\x83E\x9C\xEEA\xFD\x9D'I\v\x8E9\xFA4\x14\x1F&\xBFR\x8A\xD3\xBDL\xC64\xABf\xCD\x85\x87\x88^"
#Base64.encode64(output) => "/MpS4kyxGsqDRZzuQf2dJ0kLjjn6NBQfJr9SitO9TMY0q2bNhYeIXg==
"

Does anyone know what I'm doing wrong?

Thanks.

I haven't been able to find the $StringHelper::encrypt function, but if it is compatible, you just need to also perform cipher.final in your Ruby code and concatenate the output of update and final as clearly specified in the instructions.
