使用方法

Putty中文版保存设置技巧：
在HostName(or IP address)填入主机IP地址
在Saved Sessions下填入一点说明文字，并点击Save
这样在下一次使用putty时就可以点击保存的Sessions，打开远程连接了
建议使用Putty便携版，主机会话信息会保存到当前sshhostkeys文件夹

更新日志

These features are new in 0.83 (released 2025-02-08):

Support for ML-KEM, the NIST-standardised post-quantum key exchange mechanism. (In addition to NTRU Prime, which has been supported since 0.78.)
Support for full Unicode file names in Windows file selector dialogs. (However, these do not yet round-trip through a saved session.)
Bug fix: psftp -b works again.
Bug fix: assertion failure if an SSH connection times out at the login prompt.
Bug fix: crash in Pageant if an SSH connection is abandoned while waiting for a deferred decryption passphrase.
Bug fix: tight loop if PuTTY tried to send an empty answerback string.
Bug fix: accidental truncation of some configuration edit boxes' contents to 127 characters.
Bug fix: Windows XP support was accidentally broken, and now reinstated.
Bug fix: restored interoperation with third-party tools that auto-fill login prompts by sending ^M for Return.
Bug fix: confusion when terminal window resized by tools like FancyZones.
Bug fix: the small keypad keys didn't reliably work in the terminal on Unix.
