The crypto.randomBytes() method is used to generate cryptographically well-built artificial random data and the number of bytes to be generated in the written code....

The crypto.createCipheriv() method is an inbuilt application programming interface of the crypto module which is used to create a Cipher object, with the stated algorithm, key, and initialization vector (iv).Syntax:...

The crypto.createHash() method is used to create a Hash object that can be used to create hash digests by using the stated algorithm....

The crypto.createHmac() method is used to create an Hmac object that uses the stated ‘algorithm’ and ‘key’. Syntax:...

The crypto.createDecipheriv() method is an inbuilt application programming interface of crypto module which is used to create a Decipher object, with the stated algorithm, key and initialization vector i.e, (iv)....

The crypto.generateKeyPair() method is an inbuilt application programming interface of crypto module which is used to generate a new asymmetric key pair of the specified type. For example, the currently supported key types are RSA, DSA, EC, Ed25519, Ed448, X25519, X448, and DH. Moreover, if option’s publicKeyEncoding or privateKeyEncoding is stated here, then this function acts as if keyObject.export() had been called on its output. Else, the particular part of the key is returned as a KeyObject. However, it is suggested to encode the public keys as ‘spki’ and private keys as ‘pkcs8’ with encryption for long-term storage....

The crypto.randomUUID() is  an inbuilt application programming interface of class Crypto within crypto module which is used to generate a random RFC 4122 Version 4 UUID....

The crypto.pbkdf2() method gives an asynchronous Password-Based Key Derivation Function 2 i.e. (PBKDF2) implementation. Moreover, a particular HMAC digest algorithm which is defined by digest is implemented to derive a key of the required byte length (keylen) from the stated password, salt, and iterations....

The hash.digest( ) method is an inbuilt function of the crypto module’s Hash class. This is used to create the digest of the data which is passed when creating the hash. For example, when we create a hash we first create an instance of Hash using crypto.createHash() and then we update the hash content using the update( ) function but till now we did not get the resulting hash value, So to get the hash value we use the digest function which is offered by the Hash class....

The crypto.publicEncrypt() method is an inbuilt application programming interface of the crypto module which is used to encrypt the stated content of the buffer with the parameter ‘key’....

The crypto.verify()  is a method of the inbuilt module of node.js crypto that is used to verify the signature of data that is hashed using different kinds of hashing functions Like SHA256 algorithm etc....

The crypto.generateKeyPairSync() method is an inbuilt application programming interface of crypto module which is used to generate a new asymmetric key pair of the specified type. For example, the currently supported key types are RSA, DSA, EC, Ed25519, Ed448, X25519, X448, and DH. Moreover, if option’s publicKeyEncoding or privateKeyEncoding is stated here, then this function acts as if keyObject.export() had been called on its output. Else, the particular part of the key is returned as a KeyObject. However, it is suggested to encode the public keys as ‘spki’ and private keys as ‘pkcs8’ with a strong passphrase, in order to keep the passphrase secret....
