SSH Public Key Authentication on Cisco IOS. PKI (Public Key Authentication) is an authentication method that uses a key pair for authentication instead of a password. Two keys are generated. Let’s generate a 2048 bit RSA key pair: R1(config)#crypto key generate rsa modulus 2048 The name for the keys will be: R1.NETWORKLESSONS.LOCAL% The. As covered in my old post, to enable SSH on the ASA, we’ll need to generate RSA key pair first. Current NIST recommendation is to use 2048-bit or above. In this post, I am going to use 4096-bit key pair. ASA5506(config)# crypto key generate rsa modulus 4096 SSH Version. Configuring the Cisco ASA SSH server to accept only version 2 is best. First, you must create the keys on both devices. We recommend using at least 1024-bit keys in production networks: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#crypto key generate rsa The name for the keys will be: Router1.oreilly.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys.

Over the years, numerous cryptographic algorithms have been developed and used in many different protocols and functions. Cryptography is by no means static. Steady advances in computing and the science of cryptanalysis have made it necessary to adopt newer, stronger algorithms and larger key sizes. Older algorithms are supported in current products to ensure backward compatibility and interoperability. However, some older algorithms and key sizes no longer provide adequate protection from modern threats and should be replaced. This paper summarizes the security of cryptographic algorithms and parameters, gives concrete recommendations regarding which cryptography should be used and which cryptography should be replaced, and describes alternatives and mitigations.

The following table can help customers migrate from legacy ciphers to current or more secure ciphers. The table explains each cryptographic algorithm that is available, the operations that each algorithm supports, and whether an algorithm is Cisco's best recommendation. Customers should pay particular attention to algorithms designated asAvoid or Legacy. The status labels are explained following the table.
