Share a newly written PHP encryption and decryption function

XOR string encryption method after base64 encryption

Encryption

function encode($str,$key) { $res = base64_encode($str); $code = $res^$key; return $code; }

Decryption

function decode($str,$key) { return base64_decode($str^$key); }

Full code example:

$str = '111021'; $key = 'APPYJJ-PHONE-LAZY'; function encode($str,$key) { $res = base64_encode($str); $code = $res^$key; return $code; } $str = encode($str,$key); print_r($str); echo "
"; function decode($str,$key) { return base64_decode($str^$key); } print_r(decode($str,$key));

• The whole program is very simple~ According to logical thinking, it should be difficult to crack, if others don’t know your secret key;

• If you still feel unsafe. So I’m just going to throw some light here; I suggest you continue to use shift operations in the encryption and decryption process

//加密的时候； $a = $str >> 4; //解密的时候则相反 $a = $str << 4;

ok!~ At this point, the blogger continues to work! ~~
