求助一个PHP加密解密不区分大小写的函数？

PHP语言：比如字符串 $s = '2_中文'; 加密后得到的加密字符串，必须全部是小写，不能有特殊符号。主要是用于做二级域名。比如：xxx.abc.com 其中 xxx 就是 $s 加密后的字符串。程序里面获取 HTTP_HOST，得到 xxx，然后解密并得到 $s。下面这段是我在网上找的，不知道有没什么bug。 function encode32($str) { $BASE32_ALPHABET = 'abcdefghijklmnopqrstuvwxyz234567'; $output = ''; $v = 0; $vbits = 0; for ($i = 0, $j = strlen($str); $i = 5) { $vbits -= 5; $output .= $BASE32_ALPHABET[$v >> $vbits]; $v &= ((1 0) { $v = 'a' && $str[$i] = '2' && $str[$i] = 8){ $vbits -= 8; $output .= chr($v >> $vbits); $v &= ((1 << $vbits) - 1); } } return $output; } $s = '2_中文'; $jiami = encode32($s); $jiemi = decode32($jiami); echo '原始：'.$s.'---加密后：'.$jiami.'===解密后：'.$jiemi;

这种UE加密文件有解密的方法吗？

https://wmprod.oss-cn-shanghai.aliyuncs.com/c/user/20241002/cb52a7465a929cad27c2a843fa730bc2.png 这种UE加密文件有解密的方法吗？让它恢复加密前的格式这种触及知识盲区了，不知道该怎样尝试

PHP对接中行国密解密的解决方案或者demo？

如何做到真正的服务端加密存储，仅用户客户端解密后使用？

我现在是弄一个小程序，用户会添加非常敏感的安全信息，目前是用户端添加敏感数据时使用他的union_id和固定的key作为加解密密钥，然后再AES加密后再提交到服务端，然后下次请求服务器返回加密数据后解密再使用。这里存在一个问题，如果有黑客拿到了我的数据库，和我的算法，然后就可以解密出用户的敏感数据。因为用户union_id是会记录到服务端数据库，客户端固定的key也是可以扒到。有什么方案可以做到真的的加密云端存储，除了用户自己，其他人完全无法解密数据呢，包括我自己也无法查看用户的敏感数据？跪求各位大佬推荐一个方案
