有没有人可以使用工具来区分 RSA 公钥和 DSA 公钥？我有两个 SSH .pub 文件，我需要知道它们是 RSA 还是 DSA。

如另一个答案中所述，由于文件是 SSH.COM 格式，您可以转换为 openssh 格式并打开文件以检查ssh-dsaor ssh-rsa：

To convert your SSH.COM key to OpenSSH format use:

ssh-keygen -i -f ssh_key.pub

From the ssh-keygen manpage

 -i   This option will read an unencrypted private (or public) key
      file in SSH2-compatible format and print an OpenSSH
      compatible private (or public) key to stdout.  ssh-keygen
      also reads the `SECSH Public Key File Format'.  This option
      allows importing keys from several commercial SSH
      implementations.
 -f  Specifies the filename of the key file.

您可以使用 ssh-keygen 获取指纹并从 .pub 文件中键入：

ssh-keygen -lf id_rsa.pub
