Configuring SSH Key Generation Wait Time
SSH keys can only be generated after a configurable time interval has expired since the last key generation.
The
ssh key-gen wait-time
command specifies this wait time in seconds. The default interval is 300 seconds
(5 minutes).
Step 1
Enter the context configuration mode.
[local]
host_name
(config)#
context context_name
[local]host_name(config-ctx)#
Step 2
Specify the wait time interval.
[local]
host_name
(config-ctx)#
ssh key-gen wait-time seconds
[local]
host_name
(config-ctx)#
Notes:
•
seconds
is specified as an integer from 0 through 86400. Default = 300
Specifying SSH Encryption Ciphers
The SSH Configuration mode
ciphers
CLI command configures the cipher priority list in sshd for SSH
symmetric encryption. It changes the cipher options for that context.
Step 1
Enter the SSH Configuration mode.
[local]
host_name
(config-ctx)#
server sshd
Step 2
Specify the desired encryption algorithms.
[local]
host_name
(config-sshd)#
ciphers algorithm
Notes:
•
algorithm
is a string of 1 through 511 alphanumeric characters that specifies the algorithm(s) to be used as a single
string of comma-separated variables (no spaces) in priority order from those shown below:
•
blowfish-cbc
–
symmetric-key block cipher, Cipher Block Chaining, (CBC)
•
3des-cbc
–
Triple Data Encryption Standard, CBC
•
aes128-cbc
–
Advanced Encryption Standard (AES), 128-bit key size, CBC
•
aes128-ctr
–
AES, 128-bit key size, Counter-mode encryption (CTR)
•
aes192-ctr
–
AES, 192-bit key size, CTR
•
aes256-ctr
–
AES, 256-bit key size, CTR
•
–
AES, 128-bit key size, Galois Counter Mode [GCM], OpenSSH
•
–
AES, 256-bit key size, GCM, OpenSSH
