Are there possibilities to optimize signing? e.g., enable settings in config file.  (though I'm aware it is difficult to optimize the algorithm itself) The signing function I used here is `mbedtls_rsa_pkcs1_sign()`.  \r\n\r\nMany thanks.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/ARMmbed/mbedtls/issues/comments/203900626","html_url":"https://github.com/ARMmbed/mbedtls/issues/447#issuecomment-203900626","issue_url":"https://api.github.com/repos/ARMmbed/mbedtls/issues/447","id":203900626,"user":{"login":"ciarmcom","id":14747535,"avatar_url":"https://avatars.githubusercontent.com/u/14747535?v=3","gravatar_id":"","url":"https://api.github.com/users/ciarmcom","html_url":"https://github.com/ciarmcom","followers_url":"https://api.github.com/users/ciarmcom/followers","following_url":"https://api.github.com/users/ciarmcom/following{/other_user}","gists_url":"https://api.github.com/users/ciarmcom/gists{/gist_id}","starred_url":"https://api.github.com/users/ciarmcom/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ciarmcom/subscriptions","organizations_url":"https://api.github.com/users/ciarmcom/orgs","repos_url":"https://api.github.com/users/ciarmcom/repos","events_url":"https://api.github.com/users/ciarmcom/events{/privacy}","received_events_url":"https://api.github.com/users/ciarmcom/received_events","type":"User","site_admin":false},"created_at":"2016-03-31T12:03:48Z","updated_at":"2016-03-31T12:03:48Z","body":"ARM Internal Ref: IOTSSL-689"}}
