#### Signing:

```erlang

1> S = etsdangerous:signer(<<"secret-key>>>).

{signer,untimed,<<"secret-key">>,<<"etsdangerous.Signer">>,

        <<".">>}

2> D = etsdangerous:sign(S, <<"data">>).

<<"data.tfT7zMsPOFv84VxV6CUew_09xvs">>

3> etsdangerous:unsign(S, D).

{ok,{<<"data">>,undefined}}

```

#### Expiring signatures:

```erlang

1> S = etsdangerous:ts_signer(<<"secret-key">>, 10).

{signer,{timed,10},

        <<"secret-key">>,<<"etsdangerous.Signer">>,<<".">>}

2> D = etsdangerous:sign(S, <<"data">>).

<<"data.BCyr0A.qmWS3-TkJ9eiElgZELGmubxsuRA">>

3> etsdangerous:unsign(S, D).

{ok,{<<"data">>,{{2013,3,21},{14,33,52}}}}

...

4> etsdangerous:unsign(S, D).

{error,signature_expired}

```

#### Salt:

```erlang

1> S1 = etsdangerous:signer(<<"secret-key">>, <<"salt-1">>).

{signer,untimed,<<"secret-key">>,<<"salt-1">>,<<".">>}

2> S2 = etsdangerous:signer(<<"secret-key">>, <<"salt-2">>).

{signer,untimed,<<"secret-key">>,<<"salt-2">>,<<".">>}

3> D = etsdangerous:sign(S1, <<"data">>).

<<"data.siZlJhySx8NoTIwrmOmupfvGnO8">>

4> etsdangerous:unsign(S2, D).

{error,bad_signature}
