teaEncode / teaDecode - in-ou data mismatch

[haron4igg]

Hello,

Can somebody explain me, how could be that possible:

	local file = fileOpen("loading.dds")   
	local size = fileGetSize(file)	
	local raw = fileRead(file, size)  
	fileClose(file)

	local encoded = teaEncode(raw, "0123456789ABCDEF")
	local dencoded = teaDecode(encoded, "0123456789ABCDEF")
	outputDebugString("Raw: " .. string.len(raw))	
	outputDebugString("Encoded: " .. string.len(encoded))	
	outputDebugString("Decoded: " .. string.len(dencoded))	

	if dencoded == raw then
		outputDebugString("Test PASSED")	
	else
		outputDebugString("Test FAILED")	 
	end

Result:

 

Client v1.5.4-release-11354

Oh... never-mind. 

Tea works only with text-data. Not binary. 

In order to fix this - wrap data in-to Base64 before encoding. And unwrap after decode.

	local encoded = teaEncode(base64Encode(raw), "0123456789ABCDEF")
	local dencoded = base64Decode(teaDecode(encoded, "0123456789ABCDEF"))
	outputDebugString("Raw: " .. string.len(raw))	
	outputDebugString("Encoded: " .. string.len(encoded))	
	outputDebugString("Decoded: " .. string.len(dencoded))	
	if dencoded == raw then
		outputDebugString("Test PASSED")	
	else
		outputDebugString("Test FAILED")	 
	end

I feel awkward that this is the first time I even hear about some functions in this post  And I'm not new to MTA or LUA heh

You have to base64 encode the binary file data before you put the content through teaEncode. Look at the second code example: https://wiki.multitheftauto.com/wiki/TeaEncode#Example

He already figured it out over 8 hours ago (last update of post)
