Usage
import { decrypt, encrypt } from "krip"; const SECRET = "MY_SPECIAL_KEY"; const test = async value => { const encrypted = await encrypt(value, SECRET); console.log("encrypted: ", encrypted); const decrypted = await decrypt(encrypted, SECRET); console.log("decrypted: ", decrypted); }; test("my secret value"); // encrypted: 4439AA90B8374AA440BE3F816ADF0EA3501B61DE699264D5CAD89C381E595DD2337DCD00E7AE33F37A87C38CED // decrypted: my secret value
API
encrypt
encrypt(value: any, secret: any[, options: Object]): string
Encrypt a value
based on the passed secret
and options
. The value
can be any serializable value, as can the secret
(if not a string, under the hood they will be stringified).
const SECRET = {some: 'special key'}; const result = await encrypt({some: 'data'}, SECRET); console.log(result); // FD3740F30AEF1B25588C7227+96800272F06DCD73749802EB6FF7052614C876D30ED7398B4579295CE90FC8
options
is an object of the following possible values:
{ // charset to use when encoding / decoding text charset: string = 'utf-8', // size of the TypedArray used for the crypto iv ivSize: number = 12, // the parser used to deserialize the encrypted value parse: function = JSON.parse, // the stringifier used to serialize the secret / value to encrypt stringify: function = JSON.stringify, }
decrypt
decrypt(encryptedValue: string, secret: any[, options: Object]): string
Decrypt the encryptedValue
based on the passed secret
and options
. The secret
must be equal in value as the one used in the encrypt
method.
const SECRET = {some: 'special key'}; const encrypted = await encrypt({some: 'data'}, SECRET); console.log(encrypted); // FD3740F30AEF1B25588C722796800272F06DCD73749802EB6FF7052614C876D30ED7398B4579295CE90FC8 const result = await decrypt(encrypted, SECRET); console.log(result); // {some: 'data'}
options
is an object of the following possible values:
{ // charset to use when encoding / decoding text charset: string = 'utf-8', // size of the TypedArray used for the crypto iv ivSize: number = 12, // the parser used to deserialize the encrypted value parse: function = JSON.parse, // the stringifier used to serialize the secret stringify: function = JSON.stringify, }
generateSecret
generateSecret([options: Object]): CryptoKey
Generate a dynamic secret to use in encrypt
or decrypt
.
const SECRET = await generateSecret(); console.log(SECRET); // CryptoKey {...}
options
is an object of the following possible values:
{ // the length of the key used when generating a key keyLength: number = 256, }
hash
hash(value: any[, algorithm: string[, options: Object]]): string
Generate a unique SHA-based one-way hash.
const hashed = await hash('foo', 'SHA-1'); console.log(hashed); // 0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33
algorithm
is a string of the following possible values:
SHA-1 SHA-256 SHA-384 SHA-512
options
is an object of the following possible values:
{ // charset to use when encoding / decoding text charset: string = 'utf-8', // the stringifier used to serialize the value to hash stringify: function = JSON.stringify, }
