KeygenMe contains a bug. What is the length of TEA_KEY?
If its 8, from where next 8-bytes will come? :)

Anyway, solved and submitted :)

profdracula... length of TEA_KEY is 16 :)
but yeah contains a bug... TEA can't encode more than 8 chars... if the name uses more than 8 chars? he only are going to take 8 chars :)

Yes HMX0101, I know TEA Block-length=8 Bytes and TEA Key-length= 16 bytes. Actually my question was a tip to guyz trying to solve this keygenme :)

This keygenme uses a key that was actually not intended to be used. It gets a tail from around LOL. But name-length is not a problem, because TEA_Encrypt handles the names>8 chars, or in case of name<8 uses 0-padding :)
