* Change the counter argument for CRYPTO_chacha_20 to be 64-bits on all platforms.bcook2015-12-092-5/+6
| | | | | | | | | | | The recently-added EVP_aead_chacha20_poly1305_ietf() function, which implements informational RFC 7539, "ChaCha20 and Poly1305 for IETF Protocols", needs a 64-bit counter to avoid truncation on 32-bit platforms. The existing TLS ChaCha20-Poly1305 ciphersuite is not impacted by this, but making this change requires an ABI bump. ok jsing@, "Looks sane" beck@

* Cast Td4[] values (which are uint8_t) to uint32_t before shifting them left bymiod2015-11-051-5/+5
| | | | | | | | | 24 bits; if we don't, Td4[] gets cast to signed int, and according to C>=99 6.5.7, signed int shifted by enough bits to cause a the sign bit to be set is an UB. Reported by Pascal Cuoq on behalf of the trust-in-soft.com mafia I am {partial,slightly related} to.

* Add EVP_aead_chacha20_poly1305_ietf() - The informational RFC 7539,reyk2015-11-022-19/+113
| | | | | | | | | "ChaCha20 and Poly1305 for IETF Protocols", introduced a modified AEAD construction that is incompatible with the common style that has been already used in TLS with EVP_aead_chacha20_poly1305(). The IETF version also adds a constant (salt) that is prepended to the nonce. OK mikeb@ jsing@

* In the case where len is not a multiple of sizeof(RC4_CHUNK) the RC4 codejsing2015-10-211-63/+1
| | | | | | | | | | | | | | will end up doing a read and write of up to 7 bytes beyond the specified length. This is effectively a non-issue since we read and write back the same data and due to alignment it is within a page boundary. Regardless, avoid this by removing the "special" handling for the remaining length and allow the standard (non-chunk) code to process the remaining bytes, which does not result in overrun. Reported by Pascal Cuoq <cuoq at trust-in-soft.com> - thanks! ok beck@ miod@
