nng (nanomsg next generation) is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies. The communication patterns, also called "scalability protocols", are basic blocks for building distributed systems. By combining them you can create a vast array of distributed applications.

The amount of extra MAC calculation to perform was based on the assumption that the bulk of the time is spent in processing 64-byte blocks, which is correct for most supported hashes but not for SHA-384. Correct the amount of extra work for SHA-384 (and SHA-512 which is currently not used in TLS, and MD2 although no one should care about that).\n\nThis is a regression fix for what CVE-2013-0169 had been fixed this.\n\nCVE-2018-0498\n\nThe basis for the Lucky 13 family of attacks is for an attacker to be able to distinguish between (long) valid TLS-CBC padding and invalid TLS-CBC padding. Since our code sets padlen = 0 for invalid padding, the length of the input to the HMAC function gives information about that.\n\nInformation about this length (modulo the MD/SHA block size) can be deduced from how much MD/SHA padding (this is distinct from TLS-CBC padding) is used. If MD/SHA padding is read from a (static) buffer, a local attacker could get information about how much is used via a cache attack targeting that buffer.\n\nLet's get rid of this buffer.
