SSH 添加 : Invalid key length

Question

我的mac自动升级后，我尝试ssh-add失败:

>ssh-add
Enter passphrase for /Users/dan/.ssh/id_rsa:
Error loading key "/Users/dan/.ssh/id_rsa": Invalid key length

>ssh -V
OpenSSH_7.6p1, LibreSSL 2.6.2

但是我该如何解决这个问题？

谢谢!

Answer 1

根据 release notes对于 OpenSSH 7.6:

Refuse RSA keys <1024 bits in length and improve reporting
for keys that do not meet this requirement.

因此，您尝试导入的 key 可能太短(弱)。最好的办法是生成一个新 key 。
