This crackme needs the good unterstanding of cryptography. ;)

I think you have to patch only the public keys! Nothing other. :)

Much fun :)

little hint... MIRACL functions can be identified by this pattern:
MOV DWORD PTR DS:[ESI+EAX*4+24], XXh
binary: C7448624 XX000000
XX - function ID

Due to large curve I've replaced keys with:

113F090163487155A6F89E3A5 - Rx'
32570748F13BA0D2F3E0987A - Ry'
B12BD87CCB5F87ED6EFBA89C - k'

And then:
name: tamaroth
serial: 19264F2BDC73F274B79EBD80D-F17CB5FA4534F66D78121B50

I forgot to say in my solution that one check is missing from verification algorithm. Thus for each name, serial "0" is accepted.... :)
