Libsodium has been around for a while, so probably the reason it was posted is that version 1.0.19 was just released: https://github.com/jedisct1/libsodium/releases/tag/1.0.19-RELEASE https://github.com/jedisct1/libsodium/releases/tag/1.0.19-RE... Updated NuGet and Swift packages are going to be uploaded soon. AEGIS-128X and 256X are not there yet, but if you need them, they are available in libaegis: https://github.com/jedisct1/libaegis https://github.com/jedisct1/libaegis All the code from libaegis will eventually be merged into libsodium, including the incremental update API which is especially useful for TLS.
