(비공식) keyFmt CLI for fnsad

(비공식) fnsad용 keyFmt CLI

개요

• fnsad 를 포함한 Cosmos-SDK의 node binary는 unarmored hex 형식의 private key를 import하는 기능이 없다
• DOSI Vault의 개인 키 보기 기능은 unarmored hex를 노출한다
• "unarmored hex 형식의 private key" -> fnsad가 import 가능한 private key export 형식으로 변환툴 제공한다
• 원본은 Agoric의 dckc님 작업이고 finschia에 맞추어 살짝 수정한 것이 전부임

가정

• 샘플용 개인키(private key) : 0000000000000000000000000000000000000000000000000000000000000001
  • 주의: 이 private key는 공개된 값(0x01)이며 에 실제 자금을 넣으면 안됨
• go 1.2 이상 설치
• fnsad는 설치되어 있다고 가정
