Crioptachadh tèarainte.
Tha dàta air a chrioptachadh tro cheumannan farsaing gus prìobhaideachd agus tèarainteachd a dhèanamh cinnteach. Tha seo a’ dìon do dhàta bho bhrisidhean is aodion, le bhith a’ cleachdadh dhòighean mar AES-256.
<?php
$key = openssl_random_pseudo_bytes(32);
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('AES-256-CBC'));
$encrypted = base64_encode($iv . openssl_encrypt("Sensitive data", 'AES-256-CBC', $key, 0, $iv));
echo "Encrypted: $encrypted\n";
$decrypted = openssl_decrypt(substr(base64_decode($encrypted), $iv_len = openssl_cipher_iv_length('AES-256-CBC')), 'AES-256-CBC', $key, 0, substr(base64_decode($encrypted), 0, $iv_len));
echo "Decrypted: $decrypted\n";
?>
Cur an gnìomh balla-teine.
Bidh a’ mhòr-chuid de làraichean Baggiano a’ cleachdadh siostaman balla-teine gus IPan millteach is botaichean a bhacadh. Tha seo a’ dèanamh cinnteach gu bheil iarrtasan bho cheanglaichean neo-thèarainte air an cur dheth.
