  1. Yes, it is necessary to generate the rsa key pair for SSH access. Here is the command to check the keypair in your ASA: show crypto key mypubkey rsa. Hope that helps.
  2. Crypto key generate rsa modulus 1024 ip domain-name domain-name ip ssh version 2 ip ssh time-out 120 ip ssh authentication-retries 3 line vty 0 4 transport input telnet ssh end.

I have the n, d, e for RSA algorithm. However, I want to use privatekey to encrypt some string, generate USERCERTIFICATION, and use publickey for users to decrypt it and get the string.I know if I do so, the string can be easily decrypted by anyone, but security is not my concern at all, I just need that no one except me can generate the USERCERTIFICATION.

Crypto Key Generate Rsa Impact

Use the generateKey() method of the SubtleCrypto 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.

Examples
