From: tb Date: Mon, 10 Jan 2022 12:17:49 +0000 (+0000) Subject: Implement openssl pkey -{,pub}check and pkeyparam -check X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=d40b1e08368b3db03f32c9770d96acf3c6a3956a;p=openbsd Implement openssl pkey -{,pub}check and pkeyparam -check These expose EVP_PKEY_{,public_,param_}check() to the command line. They are currently noops and will be enabled in the upcoming bump. ok inoguchi jsing --- diff --git a/usr.bin/openssl/apps.c b/usr.bin/openssl/apps.c index 392d3cc3393..fd13371f5d3 100644 --- a/usr.bin/openssl/apps.c +++ b/usr.bin/openssl/apps.c @@ -1,4 +1,4 @@ -/* $OpenBSD: apps.c,v 1.61 2021/11/26 16:23:27 tb Exp $ */ +/* $OpenBSD: apps.c,v 1.62 2022/01/10 12:17:49 tb Exp $ */ /* * Copyright (c) 2014 Joel Sing * @@ -2262,3 +2262,31 @@ show_cipher(const OBJ_NAME *name, void *arg) fprintf(stderr, " -%-24s%s", name->name, (++*n % 3 != 0 ?
