I need to save encrypted text to my database, but I need to retrieve it afterwards, I found several examples with a password, but all one-way . and I also do not want to use the base64_encode/decode handle.
If anyone can give me a light and tell me the way, I am very grateful!
Example:
<?php
function cripto ($texto, $tipo) {
$chave = 'qwf4w58';
if ($tipo == 'encriptar') {
$texto + $chave = $texto_encriptado;
return $texto_encriptado;
} else if ($tipo == 'desencriptar') {
$texto + $chave = $texto_desencriptado;
return $texto_desencriptado;
}
}
?>
