From f3755acd5513f85ff734de6a822b6f804d3776ce Mon Sep 17 00:00:00 2001 From: jsing <> Date: Tue, 26 Aug 2014 17:47:25 +0000 Subject: Move openssl(1) from /usr/sbin/openssl to /usr/bin/openssl, since it is not a system/superuser binary. At the same time, move the source code from its current lib/libssl/src/apps location to a more appropriate home under usr.bin/openssl. ok deraadt@ miod@ --- src/usr.bin/openssl/genrsa.c | 286 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 286 insertions(+) create mode 100644 src/usr.bin/openssl/genrsa.c (limited to 'src/usr.bin/openssl/genrsa.c') diff --git a/src/usr.bin/openssl/genrsa.c b/src/usr.bin/openssl/genrsa.c new file mode 100644 index 0000000000..7844fb815f --- /dev/null +++ b/src/usr.bin/openssl/genrsa.c @@ -0,0 +1,286 @@ +/* $OpenBSD: genrsa.c,v 1.1 2014/08/26 17:47:24 jsing Exp $ */ +/* Copyright (C) 1995-1998 Eric Young (eay@cryptsoft.com) + * All rights reserved. + * + * This package is an SSL implementation written + * by Eric Young (eay@cryptsoft.com). + * The implementation was written so as to conform with Netscapes SSL. + * + * This library is free for commercial and non-commercial use as long as + * the following conditions are aheared to.
