Hello!
If we somehow got ECC private key,
can you give explanation how we can generate valid signature?
only part how to sign already prepared messages

Hi Ygnecz,
Can You write, how to create signature?

If we have Software ID AAAA-BBBB
then

-- Software ID in Integer is
198695372904

-- LicVal [ 6 ]
b'h\xc8*C.\x00'

-- License level
1

-- LIC (MT Transform REV)
b'\xcd\x82\xb0\xef\xe0\xaf\x1b\xe3\x8d?\x967\xe5\xe2\x1b\xe8'

-- Hash( LicVal ) - SignatureVerification
bytearray(b'\xae\xcf\xce,\xf765\xdd\xfe\xc2\xe8\xa02\xd1D\x1e8\x95\rz\x13<\x9b\x00\x03\xcb\xa7\x18\xacL\xf4\xd3')

Now: do I need to modify license hash or not?
How?

I think i am able to compute Elliptic Curve (Y) but there I need signature * PubKey * hash + G.

Only for education purposes, x86 is legacy mode, this generation will not work with CHR.
Please explain me steps. Thank You!

Hello, if anyone is interested and wants to research more of RouterOS, I've created a Discord server that can be joined below.
Especially:

• modifying ROS by changing the public key it uses for NPK file verification so that they can be signed with a private key other than MikroTik's (and automatically being able to modify the any package, including the system one, or creating new ones);
• modifying the system package's /nova/bin/keyman (which seems to be the one that verifies licenses) by changing the public key it uses for license verification so that they can be signed with a private key other than MikroTik's.

Do you know how to get the ECC Key Private?
