German Federal Office for Information Security requests in its technical guideline BSI TR-02102-1 RSA Keylength not shorter than 3000bits starting 2024, in the year 2023 3000bits as a recommendation. Gitea should request longer RSA Keys by default in favor of security and drop old clients which do not support longer keys. https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102.pdf?__blob=publicationFile&v=9 - Page 19, Table 1.2 --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
