Question

是否有人使用工具来区分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。

Answer 1

如另一个答案所述，由于该文件是SSH.COM格式，您可以转换为openssh格式，只需打开该文件即可检查ssh-dsa或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.

Answer 2

您可以使用ssh-keygen获取指纹并输出.pub文件：

ssh-keygen -lf id_rsa.pub
