How can I generate a Dogecoin address from a Litecoin private key?

Question

I'd like to do the following:

• I use dumpprivkey to get the private key from Litecoin wallet.
• I import this private key into Dogecoin wallet
• Which will generate a new Dogecoin address. Both will share the same private key.

The most related post I found is: What happens if you send Bitcoin to a Litecoin address?

However, when I try to directly import, it will give me the error:
{"code":-5,"message":"Invalid private key encoding"}

So now, how can I dump the private key and decode into hex and move the prefix from "L" to "D" and regenerate a WIF for dogecoin?

Is there any existing solution for it?

Answer 1

Let's assume we have this compressed Litecoin WIF private key: T4DRLwPgnkg9jyivjbbnmqJZjHRxeYTy4idAV5uwEuFdyJBGuxXE.

% echo T4DRLwPgnkg9jyivjbbnmqJZjHRxeYTy4idAV5uwEuFdyJBGuxXE | bx base58check-decode

wrapper { checksum 625264444 payload 22b207aa76eb058876c667dc64ab8eeaa0a073bc018561c2463d438a0444b70501 version 176 }

Examine 158, base58check-decode and base58check-encode for more details.
