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 However, the OpenSSL pages say that the pre-1.0.1 versions (0.9.8 and 1.0.0) are no longer maintained.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.

2016-04-25crypto: Deprecate rand_bytes/1Ingela Anderton Andin
OpenSSL has deprecated the function RAND_pseudo_bytes used by crypto:rand_bytes/1, so this function is now deprecated in OTP too. rand_bytes/3 also used this function, but was not documented so we can remove it right away. This commit also removes the fallback in generate_key to use rand_bytes/1 if strong_rand_bytes/1 throws low entropy. This is a potential incompatibility but we think it is desirable as crypto should provide cryptographically secure functions.

2016-01-28Only use supported EC curves in crypto testsDániel Szoboszlay
Avoid hardcoding EC curve names in tests where it basically doesn't matter which curve is used. Take one of the supported curbes instead. Also, when testing ECDH key generation, skip unsupported curves. These changes are to simplify dealing with exotic libcrypto builds that don't support certain curves (for example RHEL disallows < 256 bit curves). The crypto application is only able to detect the supported curves on a very coarse level (ECC support in general and GF2m curves), so it may be necessary to edit the list of curves in the crypto_ec_curves modules. But that should be the only necessary modification to make the crypto tests pass.
2016-01-27Check the result of EC_GROUP_new_curve_* callsDániel Szoboszlay
The FIPS-enabled OpenSSL on RHEL disallows the use of < 256 bit prime fields (like secp128r1 or secp160k1), and the EC_GROUP_new_cuve_GFp call would return a NULL pointer for such fields. Not checking for this failure could result in a segfault in the NIF code.
