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.

2014-05-26crypto: Fix memory leak in hmac stream functionsSverker Eriksson
The context was never deallocated.
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.

To enable it you have to modify the OSESSL variable in the ose xcomp file.
2014-02-24crypto: Add rand_seed functionLukas Larsson
This function is needed on OSs that do not automatically initialize the PRNG seed.
2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.

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.
2014-02-05crypto: Abort VM if out of memorySverker Eriksson
Nice crash instead of segv or worse.
2014-01-13crypto: selective support for GF2m curvesAndreas Schultz
Newer OpenSSL versions allow to selectively disable GF2m elliptic curves. Selectively enable GF2m curves is support for them is available.
