Question 2

Is php-encryption better than libsodium for PHP?

Accepted Answer

php-encryption is tailored for server-side PHP with a simple API, but libsodium offers broader cross-platform support and more cryptographic features. For client-side or multi-language projects, libsodium is recommended; for PHP-only backends, php-encryption is a strong choice.

Yes, via the KeyProtectedByPassword class, which allows encrypting keys with passwords. This is detailed in the class documentation, providing a secure way to handle password-derived keys.

Question 4

It requires PHP 5.6 or newer with OpenSSL 1.0.1+, but the authors recommend PHP 8.0+ for security updates. Using older, unsupported PHP versions could expose you to vulnerabilities.

Question 5

It's designed to be secure and has been reviewed by the PHP security community, but lacks a formal audit. For most applications, it's reliable, but in high-stakes environments, you might need additional validation.

Question 6

Does php-encryption work with Laravel or other frameworks?

Accepted Answer

It can be integrated, but frameworks like Laravel have native encryption solutions. Using php-encryption might add unnecessary complexity unless you need its specific features like file encryption or password-protected keys.
