Wykorzystanie mcrypt:
function encryptnow($thecipher, $thekey, $themsg) { $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($thecipher), MCRYPT_RAND); mcrypt_generic_init($thecipher, $thekey, $iv); $encrypted_text = mcrypt_generic($thecipher, $themsg); mcrypt_generic_deinit($thecipher); mcrypt_module_close($thecipher); return $encrypted_text; } function decryptnow($thecipher, $thekey, $thencrypted){ $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($thecipher), MCRYPT_RAND); mcrypt_generic_init($thecipher, $thekey, $iv); $decrypted_text = mdecrypt_generic($thecipher, $thencrypted); mcrypt_generic_deinit($thecipher); mcrypt_module_close($thecipher); return $decrypted_text; } function startEncrytpion($choice, $mykey, $msg){ if ($choice == '1'){ $cipher = mcrypt_module_open (MCRYPT_DES, '', 'ecb', ''); //algorithmdetails($cipher); return encryptnow($cipher, $mykey, $msg); }elseif ($choice == '2'){ $cipher = mcrypt_module_open (MCRYPT_3DES, '', 'ecb', ''); //algorithmdetails($cipher); return encryptnow($cipher, $mykey, $msg); }elseif ($choice == '3'){ $cipher = mcrypt_module_open (MCRYPT_RIJNDAEL_128, '', 'ecb', ''); //algorithmdetails($cipher); return encryptnow($cipher, $mykey, $msg); }elseif ($choice == '4'){ $cipher = mcrypt_module_open (MCRYPT_GOST, '', 'ecb', ''); //algorithmdetails($cipher); return encryptnow($cipher, $mykey, $msg); } } function startDecrytpion($choice, $mykey, $msg){ if ($choice == '1'){ $cipher = mcrypt_module_open (MCRYPT_DES, '', 'ecb', ''); //algorithmdetails($cipher); return decryptnow($cipher, $mykey, $msg); }elseif ($choice == '2'){ $cipher = mcrypt_module_open (MCRYPT_3DES, '', 'ecb', ''); //algorithmdetails($cipher); return decryptnow($cipher, $mykey, $msg); }elseif ($choice == '3'){ $cipher = mcrypt_module_open (MCRYPT_RIJNDAEL_128, '', 'ecb', ''); //algorithmdetails($cipher); return decryptnow($cipher, $mykey, $msg); }elseif ($choice == '4'){ $cipher = mcrypt_module_open (MCRYPT_GOST, '', 'ecb', ''); //algorithmdetails($cipher); return decryptnow($cipher, $mykey, $msg); } }
i takie proste szyfrowanie:
function Encrypt($string, $key){ $result = ''; $char = chr(ord($char)+ord($keychar)); $result.=$char; } return $result; } function Decrypt($string, $key){ $result = ''; $char = chr(ord($char)-ord($keychar)); $result.=$char; } return $result; }
Próbuję zaszyfrować tekst i wpisać go do bazy MSSQL do kolumny o typie "text"
Jednak po wyciągnięciu tych danych z bazy i odszyfrowaniu uzyskuję krzaczki.
Wiem że rozwiązania takie działają z bazą MySql. Czy zna ktoś sposób jak zapisać zaszyfrowane dane do bazy MSSQL tak
aby po wyciągnięciu ich i odszyfrowaniu uzyskać to samo co przed szyfrowaniem i zapisaniem? Niestety nie mogę korzystać
z bazy MySql.
