The crypto.createDiffieHellman() method is used to create a Diffie-Hellman key exchange object. Also, creates prime of primeLength bits with the help of an optional specific numeric generator. Moreover, if the generator is not defined, then the value 2 is used....

The ecdh.getPrivateKey() method is an inbuilt application programming interface of class ECDH within the crypto module which is used to get the private key of the Elliptic Curve Diffie-Hellman (ECDH) object. The encoding of the key can be specified using the encoding parameter and the format using the format parameter....

The x509.checkIssued() is an inbuilt application programming interface of class X509Certificate within crypto module which is used to check if this PEM encoded X509 Certificate issued by the other certificate or not....

The ecdh.getPublicKey() method is an inbuilt application programming interface of class ECDH within the crypto module which is used to get the public key of the Elliptic Curve Diffie-Hellman (ECDH) object in the specified encoding. The encoding of the key can be specified using the encoding parameter and the format using the format parameter....

The diffieHellman.computeSecret() method is an inbuilt application programming interface of class DiffieHellman within the crypto module which is used to compute the DiffieHellman (dh) secret key....

The x509.issuer is an inbuilt application programming interface of class X509Certificate within the crypto module which is used to get the issuer identification included in this certificate....

This method provides a synchronous HMAC-based Extract-and-Expand Key Derivation Function key derivation. Key of keylen bytes is derived using digest, given key, salt and info....

The x509.fingerprint256 is an inbuilt application programming interface of class X509Certificate within crypto module which is used to get the SHA-256 fingerprint of this certificate....

The cipher.setAAD() method is used in Node.js to set the additional authenticated data (AAD) for an encrypt/decrypt stream. The AAD is a chunk of data that is authenticated but not encrypted. It is useful for sending data alongside an encrypted message that needs to be authenticated but does not need to be kept secret....

In this article, we will discuss about the setAutoPadding() method in the cipher class of the crypto module in Node JS. This method is used to automatically add padding to the input data of the appropriate size. To disable the padding, one can use cipher.setAutoPadding() with the false parameter....

The x509.toJSON() is an inbuilt application programming interface of class X509Certificate within crypto module which is used to get a string containing the PEM encoded certificate....

The ecdh.getPublicKey() method is an inbuilt application programming interface of class ECDH within the crypto module which is used to set the public key of the Elliptic Curve Diffie-Hellman (ECDH) object. The encoding of the key can be specified using the encoding parameter....
