Decrypt text created with Rijndael method in powershell from a php script -

can please me php script decrypt value in php being created in powershell using rijndael key.

the powershell script i've used create below

[reflection.assembly]::loadfile('c:\windows\microsoft.net\framework\v2.0.50727\system.web.dll') | out-null  $xcadmpass = "cloudytest" $r = new-object system.security.cryptography.rijndaelmanaged  # use rijndael  symmetric key encryption $c = $r.createencryptor((1..16), (1..16))    # set key , initialisation vector 128-bytes each of (1..16) $ms = new-object io.memorystream $cs = new-object security.cryptography.cryptostream $ms,$c,"write" # target data stream, transformation, , mode $sw = new-object io.streamwriter $cs $sw.write($xcadmpass)       # write string through crypto stream memory stream $sw.close() $cs.close() $ms.close() $r.clear() [byte[]]$result = $ms.toarray()      # byte array encrypted memory stream $encpass = [convert]::tobase64string($result) 

the encrypted value yd3/yegk64jj2lui20mo8q==

i've tried using mcrypt_decrypt can't figure out correct way original text.

this i've tried

$input = "yd3/yegk64jj2lui20mo8q=="; $key = "12345678910111213141516"; $data = base64_decode($input); $iv = substr($data, 0, mcrypt_get_iv_size(mcrypt_rijndael_128, mcrypt_mode_cbc));  $decrypted = rtrim( mcrypt_decrypt(     mcrypt_rijndael_128,     $key,     substr($data, mcrypt_get_iv_size(mcrypt_rijndael_128, mcrypt_mode_cbc)),     mcrypt_mode_cbc,     $iv ), "\0" ); 

i'm going wrong somewhere appreciated.

thanks this. i'll show final code else runs similar issues.
