Function generateKeyPair

generateKeyPair(type: "rsa", options: "crypto".RSAKeyPairOptions<"pem", "pem">, callback: ((err: Error, publicKey: string, privateKey: string) => void)): void
Generates a new asymmetric key pair of the given type. RSA, RSA-PSS, DSA, EC, Ed25519, Ed448, X25519, X448, and DH are currently supported.

If a publicKeyEncoding or privateKeyEncoding was specified, this function behaves as if keyObject.export() had been called on its result. Otherwise, the respective part of the key is returned as a KeyObject.

It is recommended to encode public keys as 'spki' and private keys as'pkcs8' with encryption for long-term storage:
```
const {
  generateKeyPair
} = await import('crypto');

generateKeyPair('rsa', {
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret'
  }
}, (err, publicKey, privateKey) => {
  // Handle errors and use the generated key pair.
});
```
On completion, callback will be called with err set to undefined andpublicKey / privateKey representing the generated key pair.

If this method is invoked as its util.promisify() ed version, it returns a Promise for an Object with publicKey and privateKey properties.
Parameters

  Must be 'rsa', 'rsa-pss', 'dsa', 'ec', 'ed25519', 'ed448', 'x25519', 'x448', or 'dh'.

generateKeyPair(type: "rsa", options: "crypto".RSAKeyPairOptions<"pem", "pem">, callback: ((err: Error, publicKey: string, privateKey: string) => void)): void
Generates a new asymmetric key pair of the given type. RSA, RSA-PSS, DSA, EC, Ed25519, Ed448, X25519, X448, and DH are currently supported.

If a publicKeyEncoding or privateKeyEncoding was specified, this function behaves as if keyObject.export() had been called on its result. Otherwise, the respective part of the key is returned as a KeyObject.

It is recommended to encode public keys as 'spki' and private keys as'pkcs8' with encryption for long-term storage:
```
const {
  generateKeyPair
} = await import('crypto');

generateKeyPair('rsa', {
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret'
  }
}, (err, publicKey, privateKey) => {
  // Handle errors and use the generated key pair.
});
```
On completion, callback will be called with err set to undefined andpublicKey / privateKey representing the generated key pair.

If this method is invoked as its util.promisify() ed version, it returns a Promise for an Object with publicKey and privateKey properties.
