Instances of the Certificate class can be created using the new keyword or by calling crypto.Certificate() as a function: const { Certificate } = await import('crypto'); const cert1 = new Certificate(); const cert2 = Certificate();const { Certificate } = require('crypto'); const cert1 = new Certificate(); const cert2 = Certificate(); certificate.exportChallenge(spkac[, encoding])# spkac | | | | encoding The encoding of the spkac string. Returns: The challenge component of the spkac data structure, which includes a public key and a challenge. const { Certificate } = await import('crypto'); const cert = Certificate(); const spkac = getSpkacSomehow(); const challenge = cert.exportChallenge(spkac); console.log(challenge.toString('utf8')); // Prints: the challenge as a UTF8 stringconst { Certificate } = require('crypto'); const cert = Certificate(); const spkac = getSpkacSomehow(); const challenge = cert.exportChallenge(spkac); console.log(challenge.toString('utf8')); // Prints: the challenge as a UTF8 string certificate.exportPublicKey(spkac[, encoding])# spkac | | | | encoding The encoding of the spkac string. Returns: The public key component of the spkac data structure, which includes a public key and a challenge. const { Certificate } = await import('crypto'); const cert = Certificate(); const spkac = getSpkacSomehow(); const publicKey = cert.exportPublicKey(spkac); console.log(publicKey); // Prints: the public key as const { Certificate } = require('crypto'); const cert = Certificate(); const spkac = getSpkacSomehow(); const publicKey = cert.exportPublicKey(spkac); console.log(publicKey); // Prints: the public key as certificate.verifySpkac(spkac[, encoding])# spkac | | | | encoding The encoding of the spkac string. Returns: true if the given spkac data structure is valid, false otherwise. import { Buffer } from 'buffer'; const { Certificate } = await import('crypto'); const cert = Certificate(); const spkac = getSpkacSomehow(); console.log(cert.verifySpkac(Buffer.from(spkac))); // Prints: true or falseconst { Certificate } = require('crypto'); const { Buffer } = require('buffer'); const cert = Certificate(); const spkac = getSpkacSomehow(); console.log(cert.verifySpkac(Buffer.from(spkac))); // Prints: true or false Class: Cipher#
Mining computers select pending transactions from a pool and check to ensure that the sender has sufficient funds to complete the transaction. This involves checking the transaction details against the transaction history stored in the blockchain. A second check confirms that the sender authorised the transfer of funds using their private key.
