That's nice. Thank you.
One of the next steps in my PHP learning project is to encrypt data on a database for user information, such as e-mail addresses.

What about a course about security in php and db? Some senior devs asked me all these stuff while interviewing me

Regarding OpenSSL, I want to input this to a MySQL database. My one question is in regards to your comment at 3 minutes, I tried setting as a BINARY type in MySQL, but it added lots of zeros to the end of the IV and this presented a warning when doing a var_dump on the returned value from the database. I can't find anything obvioua online as to why this is. Could you assist with this small point please? I very much like your clear explanation, short and to the point videos.

Thx! Can you show how to encrypt and decrypt using PGP keys? The goal would be to send encrypted /signed emails automatically. Would love to see a tutorial how to retrieve the recipients key and use it for it.

Where should we use this thing in real life practical application?? For session?

Great video on encryption. When encrypting data using PHP, do you know if the encrypted data be decrypted using other languages? Say in JS, C#, C++ etc? Thanks

Hi Dave, still waiting for yr full course in CI4 Shield. Its now 1.2.

For those who are new to encryption, please not that encryption alone is not enough, typically. You also need to authenticate which guarantees that when decrypt the ciphered text, you get the original text "Hello world!" not some gibberish text. Ckeck out these 2 sodium functions for example:

is this things defalutly implemented in frameworks like laravel?
