- Oct 15, 2014 PIX software may generate a self-signed RSA key on bootup that is 768 bits, even if a user-generated key already exists. Vulnerability scanners can identify this as a security risk. When the default RSA key is deleted, the ASA will regenerate a 768-bit RSA key on a subsequent bootup even if a user-created RSA key exists.
- Oct 02, 2015 Router(config)# crypto key generate rsa general-keys The name for the keys will be: myrouter.example.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.
Dec 26, 2013 so it looks as if there is no point in the 'crypto key generate rsa' command if i follow it up with the 'crypto key generate rsa usage-keys label sshkeys mod 1024' command, i just wanted to make sure the first wasn't need for the second to work or something screwy like that.
In a public key cryptography system, senders and receivers do not use the same key.Instead, the system defines a key pair, with one of the keys beingconfidential (private) and the other not (public).
Algorithm | Sender uses.. | Receiver uses… |
---|---|---|
Encryption | Public key | Private key |
Signature | Private key | Public key |
Unlike keys meant for symmetric cipher algorithms (typically justrandom bit strings), keys for public key algorithms have very specificproperties. This module collects all methods to generate, validate,store and retrieve public keys.

API principles¶
Asymmetric keys are represented by Python objects. Each object can be eithera private key or a public key (the method
has_private()
can be usedto distinguish them).A key object can be created in four ways:
generate()
at the module level (e.g.Crypto.PublicKey.RSA.generate()
).The key is randomly created each time.import_key()
at the module level (e.g.Crypto.PublicKey.RSA.import_key()
).The key is loaded from memory.construct()
at the module level (e.g.Crypto.PublicKey.RSA.construct()
).The key will be built from a set of sub-components.publickey()
at the object level (e.g.Crypto.PublicKey.RSA.RsaKey.publickey()
).The key will be the public key matching the given object.

A key object can be serialized via its
export_key()
method.![3650 Crypto Key Generate Rsa 3650 Crypto Key Generate Rsa](/uploads/1/2/5/8/125884080/444157923.png)

Keys objects can be compared via the usual operators and
!=
(note that the two halves of the same key,private and public, are considered as two different keys).
