@joph-auth/nd-otp-webcrypto v1.0.0
@joph-auth/nd-otp-webcrypto
@joph-auth/nd-otp-webcrypto is a simple, no dependency, library for generating and verifying HOTP and TOTP tokens.
This package uses the web crypto API
and therefore can only be used where window.crypto and window.crypto.subtle are available.
For compatibility with the NodeJS Crypto module,
you should use @joph-auth/nd-otp-nodecrypto instead.
Note: The web and node versions of this package are fully compatible with each other.
