2016-12-02crypto.c: Disable broken code for ChaCha and Poly1305Björn Gustavsson
In June 2014, fb9d36c2c7c1 added support for the AES GCM ciphers (ChaCha/Poly1305) based on a development version of OpenSSL 1.1.0. The code is seriously broken when used with the released OpenSSL 1.1.0.

2016-09-28Fix aes_gcm test case in crypto_SUITEMagnus Henoch
In one of the test cases, the IV is 8 bytes. In FIPS mode, the minimum allowed IV length is 12 bytes, so let's skip that test case.
2016-09-28Use proper test data for FIPS mode negative testsMagnus Henoch
block_crypt_nif does some sanity tests on its arguments before trying to initialise the cipher. This made some of the tests in crypto_SUITE fail, since they were expecting notsup, not badarg. Fix this by passing the same test data as for the positive tests.

2016-09-28Skip FIPS tests if we cannot enable FIPS modeMagnus Henoch
Even if Erlang/OTP has been built with --enable-fips, it's possible that the OpenSSL library we're linked to doesn't support FIPS mode. In that case, it will fail to enable it at run time. Let's handle that in crypto_SUITE, by skipping the tests instead of failing.
2016-09-28Update test suites with FIPS mode supportDániel Szoboszlay
Every algorithm is now tested in both FIPS and non-FIPS modes (when crypto is compiled with FIPS support). In FIPS mode non-FIPS algorithms are disabled and the tests verify that they crash with notsup error as expected. In FIPS mode RSA and EC algorithms don't work if the key sizes are below a minimum required value - which happened to be the case with most keys used in the tests. These tests were changed to use longer keys (even in non-FIPS mode for simplicity). Conflicts: lib/crypto/test/crypto_SUITE.erl
2016-09-28Support using OpenSSL in FIPS modeDániel Szoboszlay
FIPS mode support needs to be enabled at compile time, by configuring Erlang/OTP with --enable-fips option. In FIPS mode the non-FIPS algorithms are disabled and raise error notsup. The supported protocols list is properly updated in FIPS mode to advertise only the enabled protocols. FIPS mode is off by default even if Erlang/OTP was built with FIPS support. It needs to be turned on at runtime. The official approach is to set the fips_mode application environment parameter of the crypto application to true. This would turn FIPS mode on when the NIF is loaded and would prevent loading the module on error. Another method is provided via the crypto:enable_fips_mode/1 function, but it is not recommended to be used in production, as it won't prevent the use of the crypto module in case of an error, and would risk OpenSSL crashing the emulator. It is very useful for test suites however that need to check both validated and non-validated functionality. This commit is based on commit 00b3a04d17a653b4abddeebd6dd8a2c38df532d0.
2016-09-28Fix erlang:error/2 calls in crypto.erlMagnus Henoch
Make all calls to erlang:error/2 specify the actual argument list of the function. This ensures that the stacktrace contains the correct arity of the function where the error occurred.

2016-09-22Fix compilation when OpenSSL doesn't support RC4Andreas Schultz
When OpenSSL has been configured with the "no-rc4" option, the header file rc4.h doesn't exist, and neither does the rc4 functions. Let's handle those by checking whether OPENSSL_NO_RC4 is defined.

2016-09-19Use more correct delimiters for erl_nif.h includeTuncer Ayaz
Anywhere but the beam sources we shouldn't #include "erl_nif.h", because what "erl_nif.h" does is: (1) fail to find it outside of -I dirs, (2) then treat it as if it was written like <erl_nif.h>. Using <erl_nif.h> skips (1). More information can be found in 6.10.2 of the C standard. Because the examples use "erl_nif.h", NIF projects in the Erlang ecosystem copy this verbatim and make the same mistake.
2016-09-14Fix compilation when OpenSSL doesn't support RC2Magnus Henoch
When OpenSSL has been configured with the "no-rc2" option, the header file rc2.h doesn't exist, and neither does the function EVP_rc2_cbc. Let's handle those by checking whether OPENSSL_NO_RC2 is defined. Also update pbe_SUITE, which uses RC2-CBC in one of the tests.

2016-07-30crypto:cmac calculating the Cipher-based Message Authentication CodePetr Gotthard
The ERL-82 issue requests a way to calculate a CMAC in Erlang. The AES128 CMAC is standartized in RFC 4493 and used e.g. for message authentication in the LoRaWAN networks. The CMAC is implemented by OpenSSL since v1.0.1, but as @IngelaAndin stated in response to the ERL-82, the current crypto implementation does not include functions that call those OpenSSL cryptolib functions. This commit introduces a new function `crypto:cmac` that calls the corresponding OpenSSL functions and calculates the CMAC. Only the cmac_nif is implemented. The incremental functions (init, update, final) are not provided because the current OpenSSL does not allow custom memory allocators like `enif_alloc_resource`. The Erlang user guide states that at least OpenSSL 0.9.8 is required, so I added few #ifdefs so the code is compatible with all versions. However, the OpenSSL pages say that the pre-1.0.1 versions (0.9.8 and 1.0.0) are no longer maintained. Even the 1.0.1 will be retired by Dec 2016. Hence I believe that adding a 1.0.1-only function like CMAC should be OK.
