From 3ee1eac27a2e3120fbdc60e12db091c082b8de21 Mon Sep 17 00:00:00 2001 From: Rich Salz Date: Wed, 5 Jul 2017 10:58:48 -0400 Subject: Standardize apps use of -rand, etc. Standardized the -rand flag and added a new one: -rand file... Always reads the specified files -writerand file Always writes to the file on exit For apps that use a config file, the RANDFILE config parameter reads the file at startup (to seed the RNG) and write to it on exit if the -writerand flag isn't used. Ensured that every app that took -rand also took -writerand, and made sure all of that agreed with all the documentation. Fix error reporting in write_file and -rand Reviewed-by: Paul Dale (Merged from https://github.com/openssl/openssl/pull/3862) --- doc/man1/rand.pod | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) (limited to 'doc/man1/rand.pod') diff --git a/doc/man1/rand.pod b/doc/man1/rand.pod index 0faf6872a2..22482033fc 100644 --- a/doc/man1/rand.pod +++ b/doc/man1/rand.pod @@ -9,7 +9,8 @@ rand - generate pseudo-random bytes B [B<-help>] [B<-out> I] -[B<-rand> I] +[B<-rand file...>] +[B<-writerand file>] [B<-base64>] [B<-hex>] I @@ -31,18 +32,23 @@ seeding was obtained from these sources.
