 ### Encoding
 ```rust

+let token = encode(&Header::default(), &my_claims, "secret".as_ref()).unwrap();
 ```
 In that example, `my_claims` is an instance of a Claims struct that derives `RustcEncodable` and `RustcDecodable`.
 The default algorithm is HS256.

 ## Algorithms
-Right now, only HMAC SHA family is supported: HMAC SHA256, HMAC SHA384 and HMAC SHA512.

-## Performance
-On my thinkpad 440s for a 2 claims struct using HMAC SHA256:

-test bench_encode ... bench:       3,301 ns/iter (+/- 465)

+The HMAC SHA family is supported: HMAC SHA256, HMAC SHA384 and HMAC SHA512 as well as the RSA PKCS1: RSA_PKCS1_SHA256,
+RSA_PKCS1_SHA384 and RSA_PKCS1_SHA512.
