OTP Crypto

Pseudo one-time pad crypto library for plaintext data exchange.

Installation

npm install otp-crypto --save

Demo

Demo - can be found under demo/index.html

API

Please refer to the source of truth: otp-crypto.d.ts

Example

1// Generate a random byte array key with a predefined length:
2let keySender = OtpCrypto.generateRandomBytes(1000)
3let keyReceiver = keySender.slice(0) // copy of key, which in real-life needs to be exchanged somehow
4
5// Encrypt a message to Base64 with the sender's key:
6const secretMessageUnencrypted = 'TOP SECRET MESSAGE.'
7const otpEncrypted = OtpCrypto.encrypt(secretMessageUnencrypted, keySender)
8keySender = otpEncrypted.remainingKey
9
10// Decrypt the message to plaintext with the receiver's key:
11const otpDecrypted = OtpCrypto.decrypt(otpEncrypted.base64Encrypted, keyReceiver)
12keyReceiver = otpDecrypted.remainingKey
13
14// Extract the decrypted message
15const secretMessageDecrypted = otpDecrypted.plaintextDecrypted // 'TOP SECRET MESSAGE.'
16
17// Now both sender and receiver have the same key again (shorter than before).
18// They can continue sending more messages with the remaining key.
