DGS-6604 m crypto key crypto key To generate and configure an RSA or DSA key pair, use the crypto key command. crypto key { rsa|dsa } NBITS [ force ] Syntax Description rsa Configure an RSA key pair. dsa Configure a DSA key pair. NBITS Specifies the size of the key pair(s): For RSA the valid values are 512, 768, 1024, and 2048. For DSA the valid values are 512, 768, and 1024. For SSH version 2, the minimum recommended key size is 768 bits. A key size with a larger number provides higher security but takes longer to generate. force (Optional) Regenerates the keys and suppresses the warning prompt for overwriting existing keys. Default Command Mode Usage Guideline Example None Privileged EXEC To support SSH login, an RSA or DSA key pair must first be generated. This command can generate either an RSA or DSA key to provide greater security when logging into the server using SSH. The NBITS value is required to specify the size of the key pair.
