Revision ad16671d49208ea8dcc79613e14fe6148daf959b authored by Dmitry Belyavskiy on 30 March 2020, 11:29:10 UTC, committed by Dmitry Belyavskiy on 17 April 2020, 13:21:51 UTC
The erroneously introduced names grasshopper-* replaced with kuznyechik-* according to official algorithm name translation. Too long symbolic names replaced with human-enterable ones. Also the mechanism of deprecating names in objects.txt is implemented Reviewed-by: Richard Levitte <levitte@openssl.org> Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/11440)
