4. Compile using make or self compile your specific chosen mfkey version.

• make to make all 3

or

• mfkey32v2: gcc mfkey32v2.c crypto1/crypto1.c crypto1/crypto01.c crypto1/bucketsort.c -o mfkey32v2 -Iinclude
• mfkey32: gcc mfkey32.c crypto1/crypto1.c crypto1/crypto01.c crypto1/bucketsort.c -o mfkey32 -Iinclude
• mfkey64: gcc mfkey64.c crypto1/crypto1.c crypto1/crypto01.c crypto1/bucketsort.c -o mfkey64 -Iinclude

now that youve compiled youre ready to use!

Mfkey32v2 usage

Mfkey32v2 works by two sets of 32 bit keystream authentication and is different to mfkey32 in the way it uses an alternate calculation method to generate the key

command syntax for mfkey32v2 is ./mfkey32v2 <uid> <nt> <nr_0> <ar_0> <nt1> <nr_1> <ar_1>

example: UID 939be0d5

syntax: ./mfkey32v2 939be0d5 4e70d691 b3a576be 02c1559b c6efb126 d24dd966 03fc7386

Mfkey32 usage
