Hashing

This feature allows you to create a hash of some data using various algorithms like SHA256. The example code demonstrates how to hash the string 'some data' and get a hexadecimal digest.

const crypto = require('crypto-browserify');
const hash = crypto.createHash('sha256').update('some data').digest('hex');

HMAC

HMAC stands for Hash-based Message Authentication Code. This feature allows you to create an HMAC to verify the integrity and authenticity of a message with a secret key. The example code shows how to create an HMAC for the string 'some data' using the SHA256 algorithm and a secret key.

const crypto = require('crypto-browserify');
const hmac = crypto.createHmac('sha256', 'a secret').update('some data').digest('hex');

Encryption/Decryption

This feature allows you to encrypt and decrypt data. The example code demonstrates how to encrypt the string 'some data' with the AES-256-CBC algorithm and a password, and then how to decrypt it back to its original form.

const crypto = require('crypto-browserify');
const cipher = crypto.createCipher('aes-256-cbc', 'a password');
let encrypted = cipher.update('some data', 'utf8', 'hex');
encrypted += cipher.final('hex');

const decipher = crypto.createDecipher('aes-256-cbc', 'a password');
let decrypted = decipher.update(encrypted, 'hex', 'utf8');
decrypted += decipher.final('utf8');

Signing/Verifying

This feature allows you to sign data to prove its origin and integrity, and to verify signatures. The example code shows how to sign the string 'some data' with a private key and then verify the signature with the corresponding public key.

const crypto = require('crypto-browserify');
const sign = crypto.createSign('SHA256');
sign.update('some data');
const signature = sign.sign('a private key', 'hex');

const verify = crypto.createVerify('SHA256');
verify.update('some data');
const isValid = verify.verify('a public key', signature, 'hex');
