PHPSecLib VS Halite

I recommend using PHPSecLib which has a powerful SSH library that is far more versatile than the official PHP SSH extension.

I did a lot of research on how to perform this validation. In many blogs, I saw many people recommending using native functions like openssl_verify, openssl_get_publickey, or openssl_pkey_get_details, but unfortunately, they didn't work for what I needed (Remember, an SSH key is different from an SSL key, so these functions won't work). In other forums, I saw people suggesting using the package https://phpseclib.com/. But think about it, why install a package when you're only going to use one class and one of its methods?

ports: phpseclib 3.0.19[1]

PHP libraries that provide support for asymmetric encryption OpenSSL: https://www.php.net/manual/en/book.openssl.php phpseclib: https://github.com/phpseclib/phpseclib Sodium: https://www.php.net/manual/en/book.sodium.php

And also, another strategy is to look through the Unit tests on the project, so you can see how it's actually used. for example: https://github.com/phpseclib/phpseclib/blob/master/tests/Unit/Crypt/RSA/ModeTest.php

You can also use phpseclib (PHP Secure Communications Library), which has all kinds of security-related functions, including functions for symmetric encryption. It uses a pure PHP implementation, so you don't need libraries like openssl or libsodium, but they will be used when installed (for speed).

I'm trying to find a PHP package that will handle PGP encryption/decryption. Halite keeps coming up but I can't tell from searching if it handles PGP. If it doesn't, can you recommend a PHP package that does? Thanks!

Sounds like https://github.com/paragonie/halite. What does this do better?

One of the Golden Rules of Computing is "Never roll your own Crypto" (without a PhD in Cryptography). If you need to encrypt something at rest I'd recommend the really very excellent Halite Library.

10,000%. I love Halite.

Excellent job! I've been using the https://github.com/paragonie/halite library on top of Sodium just so I don't have to re-work everything out, but this is going to be nice for cases when including third party libraries isn't possible!
