Methods of Signing with GPG

Last updated March 28, 2021

There are now two ways to approach this:

1. Using gpg and generating keys
2. Using Kryptonite by krypt.co

    map <U>(fn: (a: T) => U): Option<U>;
    isSome(): boolean;
    isNone(): boolean;
    isSomeAnd(fn: (a: T) => boolean): boolean;
    isNoneAnd(fn: () => boolean): boolean;
    unwrap(): T;
    unwrapOr(def: T): T;
    unwrapOrElse(f: () => T): T;
    map<U>(f: (a: T) => U): Option<U>;
