Why I can't import private key to metamask?

Question

I'm new. Sorry for the question. Please, help me to understand why I can't import a similar private key to metamask:

FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE8AF48A04CBFD47E8CB0366361 how I can fix this?

Cheers

Answer 1

Because it is not a valid secp256k1 private key.

From Secp256k1 the order of the generator G is

FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364141
                                           |

Which is smaller that the private key

FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE8 AF48A04C BFD47E8C B0366361 
                                           |
