(If you need a full and easy to use framework with symmetric cipher and MAC included, please have a look at [libnacl](http://nacl.cr.yp.to) or [libsodium](https://github.com/jedisct1/libsodium) which are both great.)\n\nIf you need just ed25519-signatures or x25519-key-exchange with a simple API, however, libeddsa may be for you: It is small (under 90kb) and quite fast.\n\n\n### Features:\n- written in C\n- fast and small\n- cmake build system\n- protection against timing attacks as far as possible in C\n- static and dynamic link support\n- easy to use (see wiki)\n- public domain license\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fphlay%2Flibeddsa","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fphlay%2Flibeddsa","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fphlay%2Flibeddsa/lists"}
