## 1.7.7 (2016-06-30)

* Enhancements
  * Improved handling of RSA private keys in SMF (Straightforward Method) form to CRT (Chinese Remainder Theorem) form, see [#19](https://github.com/potatosalad/erlang-jose/issues/19)  This is especially useful for keys produced by Java programs using the `RSAPrivateKeySpec` API as mentioned in [Section 9.3 of RFC 7517](https://tools.ietf.org/html/rfc7517#section-9.3).
  * Updated EdDSA operations to comply with draft 02 of [draft-ietf-jose-cfrg-curves-02](https://tools.ietf.org/html/draft-ietf-jose-cfrg-curves-02).

Example RSA SMF to CRT usage:

```erlang
%% The following map of an RSA secret key is in SMF (Straightforward Method) form.
%% Notice that we only have d, e, and n for this secret key.
JWK = jose_jwk:from(#{
  <<"d">> => <<"WSAGFGM7fSyYn5NyBL0dp3kjHjQ3djjhQoOAFasoyeE">>,
  <<"e">> => <<"AQAB">>,
  <<"kty">> => <<"RSA">>,
  <<"n">> => <<"0PM6Aooi_KYkDA1r-S24SauFpfTRc5kiPLF3a1EhuY8">>
}).

%% If we convert it back to a map, it is now in CRT (Chinese Remainder Theorem) form.
%% Notice that the dp, dq, p, q, and qi have been restored.
element(2, jose_jwk:to_map(JWK)) =:= #{
  <<"d">> => <<"WSAGFGM7fSyYn5NyBL0dp3kjHjQ3djjhQoOAFasoyeE">>,
  <<"dp">> => <<"G00J545ym1bqC9hnFDo3aQ">>,

  <<"p">> => <<"9O5YQ0w6PIpDl6c6yqwyKQ">>,
  <<"q">> => <<"2mScgy86M3q6b301UAU09w">>,

  * Preparations for future upstream OTP crypto changes.
    * Improved detection of AES CBC, ECB, and GCM support.
    * Improved detection of RSAES-OAEP, RSAES-PKCS1-v1_5, RSASSA-PKCS1-v1_5, and RSASSA-PSS support.
    * Implemented fallback RSAES-PKCS1-v1_5 and RSASSA-PKCS1-v1_5 algorithms.
    * Improved selection of encryptor for oct keys.
    * Improved algorithm support detection for jose_jwa.

* Fixes
  * Remove "sph" from jose_jws (removed from [JWS Unencoded Payload Option](https://tools.ietf.org/html/draft-ietf-jose-jws-signing-input-options-02)).

* Tests
  * Only run 1 in 10 for AES GCM and 1 in 5 for AES KW CAVP test vectors to speed up tests.
  * Additional tests for RSAES-PKCS1-v1_5 and RSASSA-PKCS1-v1_5 algorithms.

## 1.2.0 (2015-08-14)

* Enhancements
  * Add RSA PKCS-1 algorithms to support detection.
  * Add support for `crypto_fallback` option to enable/disable non-native cryptographic algorithms.
  * Add support for `json_module` option for encoding/decoding of JSON.

* Fixes
  * Fix AES GCM algorithm for non 96-bit IV values.
  * Allow RSA OAEP to specify Seed on encrypt.

* Tests
  * NIST and EMC test vectors for AES, PKCS-1, and PKCS-5.
  * Concat KDF, PBKDF1, and PKCS-7 Padding informal verification.
  * AES Key Wrap informal verification with NIST test vectors.

## 1.1.3 (2015-08-10)

* Fixes
  * Missed a case where jose was not starting automatically (see 1.1.2).

## 1.1.2 (2015-08-10)

* Enhancements
  * Automatically start jose if one of the fallback algorithms is required.

## 1.1.1 (2015-08-07)

* Fixes
  * Fix bit sizes for A128CBC-HS256, A192CBC-HS384, and A256CBC-HS512 algorithms.
  * Don't precompute the GHASH table (speeds up AES GCM fallback on OTP 17).
  * Use case statement instead of map pattern matching for block_decrypt (fixes map pattern matching bug on OTP 17).
  * Allow mostly empty EC keys to be converted back to JSON.
  * Add jose_jwk_props property test for full algorithm range of encryption and decryption.

## 1.1.0 (2015-08-06)

* Enhancements
  * Detect supported `crypto` AES ciphers and use fallbacks when necessary.
  * Detect EC key mode (to support OTP 17.5).
  * Mostly pure Erlang implementation of AES GCM and GHASH functions.
  * Add `JOSE.JWA` module for Elixir.

* Fixes
  * All tests now pass on OTP 17.5 and OTP 18.
  * Fallback to non-native crypto implementations for OTP 17.5.

## 1.0.1 (2015-08-05)

  * Use [`base64url`](https://hex.pm/packages/base64url) package from hex.pm
