どうってことない話ですが，ネット検索すると，ppkファイルからsshのキーファイルを作る方法は山ほど見つかりますが，その逆がなかなか見つからないので，メモっときます．<\/p>\n

ppkファイルは，PuTTYで使用する鍵の型式なので，基本的にはPuTTYかその付属ツールでしか作れないようです．<\/p>\n

わたしの場合は，WindowsからSSHでつなぐなんてことはしないので，OpenSSHのid_rsa鍵は各マシンに作っていますが，ppkファイルはありません．<\/p>\n

ppkファイルが必要になったのは，FileZillaでキーファイル認証のsshホストにつなぐためです．<\/p>\n

まず，PuTTYのソースからbuildします．今どきのLinuxディストロ上であれば簡単にできると思います．できあがったputtygenというツールを使います．<\/p>\n

puttygen ~\/.ssh\/id_rsa -O private -o \u30de\u30b7\u30f3\u540d\u306a\u3069.ppk<\/pre>\n
であっさりできます．<\/p>\n
Mac OS XではGTKの関係で，PuTTY本体のbuildができませんが，puttygenはできます．ただし，Makefileのうちの，<\/p>\n
WARNINGOPTS = -Wall -Werror<\/pre>\n
を<\/p>\n
WARNINGOPTS = -Wall<\/pre>\n
