Why does Cisco IOS require domain-name to be set before SSH keys can be generated? Crypto key generate rsa command without a host name and IP domain name. 2019-10-31  Cisco Bug: CSCth92454 - no crypto key generate rsa label is genarating keys in BEFORE-AFTER mode. Use this command to generate RSA key pairs for your Cisco device (such as a router). 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.

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Use the generateKey() method of the SubtleCryptohttps://energylinx754.weebly.com/blog/matlab-r2014-free-download-mac. interface to generate a new key (for symmetric algorithms) or key pair (for public-key algorithms).

Syntax

Parameters

  • algorithm is a dictionary object defining the type of key to generate and providing extra algorithm-specific parameters.
    • For RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP: pass an RsaHashedKeyGenParams object.
    • For ECDSA or ECDH: pass an EcKeyGenParams object.
    • For HMAC: pass an HmacKeyGenParams object.
    • For AES-CTR, AES-CBC, AES-GCM, or AES-KW: pass an AesKeyGenParams object.
  • extractable is a Boolean indicating whether it will be possible to export the key using SubtleCrypto.exportKey() or SubtleCrypto.wrapKey().
  • keyUsages  is an Array indicating what can be done with the newly generated key. Possible values for array elements are:
    • encrypt: The key may be used to encrypt messages.
    • decrypt: The key may be used to decrypt messages.
    • sign: The key may be used to sign messages.
    • verify: The key may be used to verify signatures.
    • deriveKey: The key may be used in deriving a new key.
    • deriveBits: The key may be used in deriving bits.
    • wrapKey: The key may be used to wrap a key.
    • unwrapKey: The key may be used to unwrap a key.

Return value

  • result is a Promise that fulfills with a CryptoKey (for symmetric algorithms) or a CryptoKeyPair (for public-key algorithms).

Exceptions

The promise is rejected when the following exception is encountered:

SyntaxError
Raised when the result is a CryptoKey of type secret or private but keyUsages is empty.
SyntaxError
Raised when the result is a CryptoKeyPair and its privateKey.usages attribute is empty.
