If I understand correctly then in the current situation it is not possible to find out what the other address is.
Thank you for your help.

I have a good reason for that, please believe me.

An old friend of mine, J-P, created a bitcoin wallet a long time ago.
The public compressed address of this wallet is 1FYPDCP1uVnPgEE3gaDMbAApdv9XYX7Si5
I need uncompressed public address now, could someone generate this ?
Thank you so much.

I’m a big Bitcoin fan ... and I recently started learning about bitcoin, private and public keys, elliptic curves, python programming, etc.

P.S: I would like to respect my friend's privacy, so please provide me a private contact if you could generate this. Thanks.
