SSH Key Pairs

• PEM format
• DSA key pair, 512 to 2048 bits in length
The DSA key pair used in the default key pair and in those generated by ROS uses a public key of 1024 bits in

length.

NOTE

DSA keys smaller than 1024 bits in length are not recommended, and support is only included here for

compatibility with legacy equipment.

NOTE

DSA key generation times increase depending on the key length. 1024-bit DSA keys take

approximately 3 minutes on a lightly loaded unit, whereas 2048-bit keys may take longer. A typical

modern PC system, however, can generate these keys in seconds.

The following (bash) shell script fragment uses the 

ssh-keygen

 command line utility to generate a 1024-bit DSA

key suitable for use in ROS. The resulting 

ssh.keys

 file, which may then be uploaded to ROS:

# DSA key size:

BITS=1024

# Make an SSH key pair:

ssh-keygen -t dsa -b 1024 -N '' -f ssh.keys

The following is an example of an SSH key generated by ROS:
