Share a freshly written PHP encryption and decryption function

Base64 encryption of different or string encryption methods

Encryption

function encode ($str, $key) {    $res = Base64_encode ($STR);    $code = $res ^ $key;    return $code;}

Decrypt

function decode ($STR, $key) {    return Base64_decode ($str ^ $key);}

Complete code example:

$str = ' 111021 '; $key = ' appyjj-phone-lazy '; function encode ($str, $key) {    $res = Base64_encode ($STR);    $code = $res ^ $key;    return $code;} $str = Encode ($str, $key);p Rint_r ($STR), echo "

 

 
  
 
   
The whole procedure is very simple ~ according to logical thinking should be difficult to crack, in the case of others do not know your secret key;
 
   
If it doesn't feel safe. So I'm going to make a point here; we recommend that you continue to use the shift operation during the encryption and decryption process.
 
  

 
When encrypting, $a = $str >> 4;//decryption is the opposite of $ A = $str << 4;
Ok!~, the blogger continues to work! ~~
