Graham	3f59e1764c	Store individual XteaKey components separately This allows us to make them private (rather than internal) and the type as a whole is immutable. It does mean we need to convert the key to an IntArray every time we use it now. However, I hope that the JVM will be smart enough to inline the toIntArray() method and also smart enough to realise it doesn't escape, allowing it to allocate it on the stack rather than the heap. This commit also adds methods for converting XteaKeys to hex, and converting from hex/integer arrays to an XteaKey object. Signed-off-by: Graham <gpe@openrs2.dev>	4 years ago

Graham	95c97b8399	Add XteaKey inline class with ZERO "constant" and isZero method Unfortunately we can't use the compiler to guarantee k isn't changed, though making it internal will help. When the JVM (and Kotlin) get value types, we might be able to improve on this (e.g. by making it an inline class of four integers). Signed-off-by: Graham <gpe@openrs2.dev>	4 years ago

Graham	4da1c5c3cf	Fix XTEA en/decryption if the index is not a multiple of the block size This commit updates the tests to ensure all combinations of 0-7 bytes of leading/trailing blocks of unencrypted bytes work correctly with all test vectors. Signed-off-by: Graham <gpe@openrs2.dev>	5 years ago

Graham	2f3cdca12d	Reduce use of temporary files The Resource::compress method already holds entire files in memory at once, as does the client-side loader. We might as well do the same on the server-side. Signed-off-by: Graham <gpe@openrs2.dev>	5 years ago
Graham	3c051fe8c1	Rename private.key to game.key This name is slightly more descriptive and consistent with loader.p12, which also contains a private key. I've also removed the public.key file. It isn't read by OpenRS2 and the two files could get out of sync with each other, which would be confusing. It's easy to extract the public key with OpenSSL if necessary: openssl pkey -in game.key -pubout -out public.key Signed-off-by: Graham <gpe@openrs2.dev>	5 years ago
