Description
Use the public-key local export dsa command to export the current switch’s DSA key pair to a
specified file.
If you specify a filename, the command exports the public key to the specified file and saves it;
otherwise, the command displays the public key on the screen.
z
SSH2 and OpenSSH are two public key formats. You can choose one as required. For example, if
you want to export the DSA host public key to a file in the SSH2 format, use the public-key local
export dsa ssh2 filename command.
z
The host public key displayed on the screen is in a format that is not transformed and cannot be
used as the public key data for public key configuration.
Related commands: public-key local create .
Examples
# Generate a DSA key pair.
<Sysname> system-view
[Sysname]public-key local create dsa
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Input the bits in the modulus[default = 1024]:
