* Make Stream_Cipher::set_iv() pure virtualRené Korthaus2016-07-205-7/+15
| | | | | | | | | | It provided a default implementation that only checked that the length was correct, but ignored the actual data and did not notify the caller, which seemed like a rather odd behaviour. The only implementation that used this default implementation, RC4, now throws an exception.

|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds Stateful_RNG base class which handles reseeding after some amount of output (configurable at instantiation time, defaults to the build.h value) as well as detecting forks (just using pid comparisons, so still vulnerable to pid wraparound). Implemented by HMAC_RNG and HMAC_DRBG. I did not update X9.31 since its underlying RNG should already be fork safe and handle reseeding at the appropriate time, since a new block is taken from the underlying RNG (for the datetime vector) for each block of output. Adds RNG::randomize_with_input which for most PRNGs is just a call to add_entropy followed by randomize. However for HMAC_DRBG it is used for additional input. Adds tests for HMAC_DRBG with AD from the CAVS file. RNG::add_entropy is implemented by System_RNG now, as both CryptGenRandom and /dev/urandom support receiving application provided data. The AutoSeeded_RNG underlying type is currently selectable in build.h and defaults to HMAC_DRBG(SHA-256). AutoSeeded_RNG provides additional input with each output request, consisting of the current pid, a counter, and timestamp (unless the application explicitly calls randomize_with_input, in which case we just take what they provided). This is the same hedge used in HMAC_RNGs output PRF. AutoSeeded_RNG is part of the base library now and cannot be compiled out. Removes Entropy_Accumulator type (which just served to bridge between the RNG and the entropy source), instead the Entropy_Source is passed a reference to the RNG being reseeded, and it can call add_entropy on whatever it can come up with.
| * Address some review comments from @cordneyJack Lloyd2016-07-179-27/+29
| | | | | | | | | | | | | | | | | | Use consistent naming for the max output before reseed parameter. The constant (default) value is renamed to BOTAN_RNG_DEFAULT_MAX_OUTPUT_BEFORE_RESEED, since without the DEFAULT_ it reads like a compile time maximum instead. Use uint8_t instead of byte.

Start removing the io buffer from entropy poller. Update default RNG poll bits to 256. Fix McEliece test, was using wrong RNG API. Update docs.

| * If EPERM when writing to the random device, return silently.Jack Lloyd2016-07-171-1/+13
| | | | | | | | | | | | | | | | | | That failure seems like an explicit system policy decision, so accept it as such. Versus say EBADF or EFAULT which would instead suggest a library bug. This return is seen on OS X Travis CI, unclear if this is a problem with OS X or with how Travis does OS X containers.
| * Switch to HMAC_DRBG for all RNG generation.Jack Lloyd2016-07-1711-241/+414
| | | | | | | | | | | | | | | | Add support and tests for additional_data param to HMAC_DRBG Add Stateful_RNG class which has fork detection and periodic reseeding. AutoSeeded_RNG passes the current pid and time as additional_data

In addition to the already present XOR-encrypion/decryption mode it's now possible to use DLIES with a block cipher. Previously the input to the KDF was the concatenation of the (ephemeral) public key and the secret value derived by the key agreement operation: ``` secure_vector<byte> vz(m_my_key.begin(), m_my_key.end()); vz += m_ka.derive_key(0, m_other_key).bits_of(); const size_t K_LENGTH = length + m_mac_keylen; secure_vector<byte> K = m_kdf->derive_key(K_LENGTH, vz); ``` I don't know why this was implemented like this. But now the input to the KDF is only the secret value obtained by the key agreement operation. Furthermore the order of the output was changed from {public key, tag, ciphertext} to {public key, ciphertext, tag}. Multiple test vectors added that were generated with bouncycastle and some with botan itself.

| | | | | | | | | | | | | | | | | | | | In 10.8 (and presumably older) versions, the header for SecRandomCopyBytes is SecRandom.h, and Security.h does not include SecRandom.h With this change, the include of Security.h may be redundant for all versions, but I have no way to test this. GH #528

* Add test vectors for block cipher padding modesRené Korthaus2016-07-112-2/+5
| | | | | | | | | | | Exports get_bc_pad() to be used from tests. Adds separate handcrafted tests for block cipher padding modes. They were previously only tested implicitly during the block cipher modes of operation tests, though not all padding modes were covered. And in case a mode of operation is not part of the enabled modules, the previously tested padding modes are not covered at all. Fixes an off-by-one bug in the previously untested ANSI X9.23 padding mode, where the number of zero bytes in the pad was one more than allowed by the standard.
