2015-12-01crypto: Avoid bug in OpenSSL-0.9.8 for ECB ciphersSverker Eriksson
that make EVP_CIPHER_iv_length() return non-zero value. Seems to be fixed in 0.9.8m.

2015-11-17Fix bug for aes_cfb_128_encrypt with empty binarySverker Eriksson
causing OpenSSL 0.9.8h to crash with evp_enc.c(282): OpenSSL internal error, assertion failed: inl > 0
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.
2015-07-10ose: Remove all code related to the OSE portLukas Larsson
The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

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.

OTP-11725 * sverk/crypto/nomem-abort: crypto: Abort VM if out of memory
2014-02-12crypto: Fix bug when using old hmac contextSverker Eriksson
Symptom: Using an old context (that had already been passed as argument to either hmac_upgrade or hmac_final) could cause VM crash or worse. Reason: Only a shallow copy (memcpy) of the context was made causing a new context to partly mutate its parent context into an inconsistent state. Problem: Only OpenSSL v1.0 supports deep copy of hmac context. It is thus not possible to implement a functional interface for older OpenSSL versions (0.9.8) which still have wide spread use. Solution: Change hmac contexts into a mutable state using NIF resources. Document reuse of old contexts as undefined. Future: If a need for reusing old context variables arise, a new hmac_copy function could be introduced that is only supported for OpenSSL v1.0.
