* Reorganize eddsa, based on patch by Daiki Ueno.Niels Möller2019-12-301-17/+16
| | | | | | | | | | | | | | | | | | | | * eddsa-internal.h (struct ecc_eddsa): New struct for eddsa parameters. * ed25519-sha512.c (_nettle_ed25519_sha512): New parameter struct. * eddsa-expand.c (_eddsa_expand_key): Replace input struct nettle_hash with struct ecc_eddsa, and generalize for ed448. Update all callers. * eddsa-sign.c (_eddsa_sign): Likewise. * eddsa-verify.c (_eddsa_verify): Likewise. * eddsa-compress.c (_eddsa_compress): Store sign bit in most significant bit of last byte, as specified by RFC 8032. * eddsa-decompress.c (_eddsa_decompress): Corresponding update. Also generalize to support ed448, and make validity checks stricter. * testsuite/eddsa-sign-test.c (test_ed25519_sign): New function. (test_main): Use it. * testsuite/eddsa-verify-test.c (test_ed25519): New function. (test_main): Use it.
* abi: explicitly export intended symbols and hide othersNikos Mavrogiannopoulos2018-07-071-0/+1
| | | | | | | | | | | | | This adds all exported symbols in the map files explicitly under the following rules: - Symbols mentioned in internal headers go in a section which is valid only for testing, and linking with these symbols will break in library updates. - Symbols mentioned in installed headers go in the exported sections and are considered part of the ABI. - All internal symbols move to internal headers. - The _nettle_md5_compress and _nettle_sha1_compress become exported without the _nettle prefix, due to existing usage.
