2016-05-26crypto: Add OpenSSL_version macrosSverker Eriksson

2016-05-26crypto: Allow any AES-GCM tag length for non-EVP implSverker Eriksson
Same fix as was done for EVP in f4f588683dce36c447017.

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.

2016-01-27Check 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.

2015-11-17crypto: Refactor nif code to use EVP interfaceSverker Eriksson
Using the generic EVP_* API makes it possible to unify algorithm-specific nif functions to a single generic function. Effectively the same change that took place on the Erlang API in R16B01 is now applied to the C code. The old implementation using the low-level API is kept for compiling against old OpenSSL, as parts of the EVP API were introduced in OpenSSL 1.0.0. There are various minor improvements as well: - supported algorithms are now provided by the nif code (not a mix of the C and Erlang code) - remove unnecessary variables and macro definitions Most of the changes in this commit comes from Dániel Szoboszlay https://github.com/dszoboszlay/otp/commit/07f7056f955b324df4ace which is part of his 'fips' branch. Now also rebased on master branch.

2015-04-09crypto: Fix undefined symbol EVP_CIPHER_CTX_newSverker Eriksson
Use a stack allocated context and EVP_CIPHER_CTX_init/cleanup instead of dynamic EVP_CIPHER_CTX_new/free that does not exist in older 0.9.8 versions.

2015-02-04Accept all valid key sizes in aes_cfb functionsKelly McLaughlin
Despite the confusion caused by the name, aes_cfb_8_crypt and aes_cfb_128_crypt can use key lengths of 128, 192, or 256. The integer in the function name refers to the block size for CFB mode. Change the aes_cfb_8_crypt and aes_cfb_128_crypt functions to accept and use keys of length 128, 192, or 256. Also augment the existing testing for these functions using the NIST test vectors for the additional key lengths to ensure the changes function properly.

2014-05-15Fix bug in SRP implementationPaul Guyot
SRP didn't work with smaller primes as user secret was improperly computed. Formula is: (B - (k * g^x)) ^ (a + (u * x)) % N Previously, the code computed a + (u * x) % N instead of a + (u * x). a typically is a 256 bits random number (RFC 5054 says it should be at least 256 bits), u and x are SHA1 signatures (160 bits). So a + (u * x) can differ from a + (u * x) % N for N primes smaller than 320 bits.
