A security key is a SHA1 hash containing necessary data used on the client and RCC connection handshake fed to Rot13, It looks like this unhashed: VersionNumber+ClientType+Salt (ex: 0.x.0pcplayersalthere)

The client type can be pcplayer, androidapp, iosapp and macplayer while the salt is stored on the RCC as <code>askljfLUZF</code> and it's technically there for security purposes (u can replace it by searching it on the rcc binary via HxD)
== Tutorial ==
=== Generating a Security Key ===
* Go onto this website https://md5decrypt.net/en/Sha1/
* Type in your version number followed by the client type and the salt (ex: 0.x.0pcplayersalthere) and then encrypt
* Copy the SHA1 hash and go to https://rot13.com/
* Paste in the SHA1 hash and you should get your new security key
=== How to Replace it ===
WARNING: Make sure to do this correctly, if not you may land on a BitStream error or version compatibility errors
* Open up your client on x32dbg
* Go to Symbols and click RobloxPlayerBeta.exe (or whatever ur client binary is named)
* Right click -> Search For -> Current Module -> String References
* After it's done fetching all the strings click on Regex and type <code>^.[A-Za-z0-9]{40}.$</code> (If it does not pop up try <code>^.[A-Qa-q0-9]{40}.$</code>)
* When it pops up click on it and then open up the comment, copy the current Security key and then you're done with x32dbg
* Open up the client with HxD and search for that specific security key you copied
* Once searched, replace it with your new one and save the file
=== Replacing the salt ===
WARNING: Make sure your new salt is exactly the length as the original and that it's implemented on your security key
* Open up your RCC on HxD
* Click CTRL+F and search up <code>askljfLUZF</code> and click OK
* Once searched, replace the salt with your new one and save the file
