-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2019-707f5271ca 2019-06-19 02:27:51.848259 --------------------------------------------------------------------------------
Name : libsodium Product : Fedora EPEL 7 Version : 1.0.18 Release : 1.el7 URL : http://libsodium.org/ Summary : The Sodium crypto library Description : Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more. It is a portable, cross-compilable, installable, packageable fork of NaCl, with a compatible API, and an extended API to improve usability even further. Its goal is to provide all of the core operations needed to build higher-level cryptographic tools. The design choices emphasize security, and "magic constants" have clear rationales.
The same cannot be said of NIST curves, where the specific origins of certain constants are not described by the standards. And despite the emphasis on higher security, primitives are faster across-the-board than most implementations of the NIST standards.
-------------------------------------------------------------------------------- Update Information:
** Version 1.0.18** - A test that didn't work properly on Linux systems with overcommit memory turned on has been removed. This fixes Ansible builds. - Emscripten: `print` and `printErr` functions are overridden to send errors to the console, if there is one. - Emscripten: `UTF8ToString()` is now exported since `Pointer_stringify()` has been deprecated. - Libsodium version detection has been fixed in the CMake recipe. - Generic hashing got a 10% speedup on AVX2. - New target: WebAssembly/WASI (compile with `dist- builds/wasm32-wasi.sh`). - New functions to map a hash to an edwards25519 point or get a random point: `core_ed25519_from_hash()` and `core_ed25519_random()`. - `crypto_core_ed25519_scalar_mul()` has been implemented for `scalar*scalar` `(mod L)` multiplication. - Support for the Ristretto group has been implemented, for compatibility with wasm-crypto. - Improvements have been made to the test suite. - Portability improvements has been made. - `getentropy()` is now used on systems providing this system call. - `randombytes_salsa20 has been renamed to `randombytes_internal`. - Support for (p)nacl has been removed. - Most `((nonnull))` attributes have been relaxed to allow 0-length inputs to be `NULL`. - The `-ftree-vectorize` and `-ftree-slp-vectorize` compiler switches are now used, if available, for optimized builds. --------------------------------------------------------------------------------
