วิธีแก้ปัญหาด้วย Plink
บันทึกสคริปต์ python นี้ไปที่known_hosts.py:
#! /usr/bin/env python
# $Id$
# Convert OpenSSH known_hosts and known_hosts2 files to "new format" PuTTY
# host keys.
# usage:
# kh2reg.py [ --win ] known_hosts1 2 3 4 ... > hosts.reg
# Creates a Windows .REG file (double-click to install).
# kh2reg.py --unix known_hosts1 2 3 4 ... > sshhostkeys
# Creates data suitable for storing in ~/.putty/sshhostkeys (Unix).
# Line endings are someone else's problem as is traditional.
# Developed for Python 1.5.2.

การทดสอบบน Win7x64 และงูหลาม 2.7
จากนั้นเรียกใช้:
ssh-keyscan -t rsa bitbucket.org >>~/.ssh/known_hosts
python --win known_hosts.py >known_hosts.reg
start known_hosts.reg
และเลือกนำเข้าสู่รีจิสทรี. คีย์สามารถดึงคีย์สาธารณะสำหรับโดเมน (ฉันมีปัญหากับ bitbucket) จากนั้นสคริปต์ python จะแปลงเป็นรูปแบบ Plink
