AuthEd25519 1.0.0

Ultra-simple high-level library for using Ed25519 to manage accounts. F# Examples:

    let _,acc = new_account()
    let _,acc2 = new_account()
    
    let verify = mk_verifier
    
    let signed_hello = acc.sign "Hello"
    let verified_hello_by_acc = verify [acc.pub] signed_hello
    let verified_hello_by_acc2 = verify [acc2.pub] signed_hello
    let verified_hello_by_acc_or_acc2 = verify [acc.pub; acc2.pub] signed_hello
    
    printfn "this was signed by 1: %A" verified_hello_by_acc
    printfn "it was not signed by 2: %A" verified_hello_by_acc2
    printfn "it was signed by either 1 or 2: %A" verified_hello_by_acc_or_acc2
    
    printfn "%A" (acc.pub.string, acc.priv.string)
    
    let accdb =
        AuthEd25519.sload_account
            "sCCwEDMG7DD+IuFjJPmWjNX9XCbwO3PlssXVHoBS6Ww="

    let verifydb = AuthEd25519.mk_verifier [AuthEd25519.spub "sCCwEDMG7DD+IuFjJPmWjNX9XCbwO3PlssXVHoBS6Ww="]
    
    let proof_Mircea_owns_razor_flame = accdb.sign "(Mircea, razor_flame)"
    
    printfn "Proof of ownership that is only valid if database signed it: %A" <| verifydb proof_Mircea_owns_razor_flame
