$mol_crypto2

Simple and fast API for effective cross platform cryptography with minimal extra size. Uses SHA-1 and Curve25519.

Hashing

Fast sync implementation of SHA-1 (20B, 160b).

const data = new Uint8Array([ 1, 2, 3 ]) // 3 B
const hash = $mol_crypto2_hash( data ) // 20 B

Signing & Verifying

Native async implementation of Ed25519.

Auditor = 32B public key for sign verification.
Signer = Auditor + 32B private key for signing.
Sign = 64B signature of data.

const Alice = await $mol_crypto2_signer.generate() // 64 B
const Bella = await $mol_crypto2_signer.generate() // 64 B

const data = new Uint8Array([ 1, 2, 3 ]) // 3 B
const digest = $mol_crypto2_hash( data ) // 20 B
const sign = await Alice.sign( digest ) // 64 B

const auditor = Alice.auditor() // 32 B
const verified = await auditor.verify( digest, sign ) // true

Encryption & Decryption

Native async implementation of x25519.

Socket = 32B public key for encryption/decryption.
Cipher = Socket + 32B private key for encryption/decryption.
Nonce = 16B unique bytes. May be predictable.

const Alice = await $mol_crypto2_cipher.generate() // 64 B
const Bella = await $mol_crypto2_cipher.generate() // 64 B

const secret = Bella.secret( Alice.socket() ) // 16 B
// const secret = Alice.secret( Bella.socket() ) // same

const data = new Uint8Array([ 1, 2, 3 ]) // 3 B
const nonce = $mol_crypto2_nonce() // 16 B

const closed = await secret.encrypt( data, nonce ) // 16 B
const opened = await secret.decrypt( closed, nonce ) // 3 B

Signing & Verifying & Encryption & Decryption

Composition of Ed25519 and x25519.

const Alice = await $mol_crypto2_private.generate() // 128 B
const Bella = await $mol_crypto2_private.generate() // 128 B

const secret = await Alice.cipher().secret( Bella.socket() ) // 16 B
// const secret = await Bella.cipher().secret( Alice.socket() ) // same

const data = new Uint8Array([ 1, 2, 3 ]) // 3 B
const nonce = $mol_crypto2_nonce() // 16 B

const closed = await secretA.encrypt( data, nonce ) // 16 B
const digest = $mol_crypto2_hash( closed ) // 20 B
const sign = await Alice.signer().sign( digest ) // 64 B

const auditor = Alice.auditor() // 32 B
const verified = await auditor.verify( digest, sign ) ) // true
const opened = await secretA.decrypt( closed, nonce ) ) // 3 B
