//$encodingAesKey是私钥 $encrypt是密文
$aeskey = base64_decode( $encodingAesKey."=");
$iv = substr($aeskey,0,16);
$ciphertext_dec = base64_decode($encrypt);
$decrypted = openssl_decrypt($ciphertext_dec,'AES-256-CBC',$aeskey,OPENSSL_RAW_DATA,$iv);
微信小店下单解密不出来
您好，辛苦参照文档、使用调试工具来自行排查呢：

$decrypted = openssl_decrypt($ciphertext_dec,'AES-256-CBC',$aeskey,1|3,$iv); 试试看这样
