RVA, Upx+Epp, 2 Anti-Olly, serial=CleanAlgo(name)

Hmx0101's CrackMe7

Hmx0101's CrackMe6

packer = custom (junk + xor loop) + UPX, original test,
the check should have been much more complex. very original but disappointing in the end

Hmx0101's CrackMe5

original too. not difficult but entertaining.

original again. Anti-debug & unpacking, 3 serials, complex algo
