This is realy woked ? for ex, If I substract 128 pubkey from 255 pubkey, I will get 128 pubkey ?
No magic Cobras, just math on the curve. Come on man.
If someone will generate a random private key in the range of (let's keep it small to show it works and can be checked quickly):
WanderingPhilospher, can you show on this yor example:
2^255 3E2E2AE352CF04AA1BD62491AF51349B559F52CDBD2140A7A8C072A1FAE6FFD5
shift to 2^128
this is a public keys of 3E2E2AE352CF04AA1BD62491AF51349B559F52CDBD2140A7A8C072A1FAE6FFD5 :

?
I now not really understand and trust this method(dividing of pubkey what can be worked...) and I hope you can help understand me more
Thanks.
