How do you Encrypt and Decrypt a PHP String

Question

What I mean is:

Original String + Salt or Key --> Encrypted String
Encrypted String + Salt or Key --> Decrypted (Original String)

Maybe something like:

"hello world!" + "ABCD1234" --> Encrypt --> "2a2ffa8f13220befbe30819047e23b2c" (may be, for e.g)
"2a2ffa8f13220befbe30819047e23b2c" --> Decrypt with "ABCD1234" --> "hello world!"

• In PHP, how can you do this?

Hello @kartik,

Use openssl_encrypt and openssl_decrypt

You can do something like:

$string_to_encrypt="Test";
$password="password";
$encrypted_string=openssl_encrypt($string_to_encrypt,"AES-128-ECB",$password);
$decrypted_string=openssl_decrypt($encrypted_string,"AES-128-ECB",$password);

Hope it works!!
Thank You!!
