You'll find this convention in other JS crypto stuff as well, like libraries for password hashing. Eg: https://www.npmjs.com/package/@node-rs/argon2 https://www.npmjs.com/package/@node-rs/argon2 https://www.npmjs.com/package/bcrypt https://www.npmjs.com/package/bcrypt Though the bcrypt package does provide an additional sync API.
