erlang_tc

=====

Erlang bindings for [threshold_crypto](https://github.com/poanetwork/threshold_crypto).

**NOTE**: We advise _not_ to use the `erlang_tc` module directly, preferably use the submodules for performing various threshold cryptography functions.

Usage

-----

Verfy basic secret key usage.

```erlang

1> SK0 = tc_secret_key:random().

#Ref<0.989752667.1337851906.91190>

2> SK1 = tc_secret_key:random().

#Ref<0.989752667.1337851906.91197>

3> PK0 = tc_secret_key:public_key(SK0).

#Ref<0.989752667.1337851906.91209>

4> MSG0 = <<"real news">>.

<<"real news">>

5> MSG1 = <<"fake news">>.

<<"fake news">>

6> %% correct

6> tc_pubkey:verify(PK0, tc_secret_key:sign(SK0, MSG0), MSG0).

true

7> %% wrong key

7> tc_pubkey:verify(PK0, tc_secret_key:sign(SK1, MSG0), MSG0).

false

8> %% wrong msg

8> tc_pubkey:verify(PK0, tc_secret_key:sign(SK0, MSG1), MSG0).

false

```
