Excellent, thanks. Do you know how many versions back SHA256 is supported? The reason I ask is that I've got an older version running on a Ubuntu VM (OpenSSL 0.9.8o 01 Jun 2010), and I tried to generate a CA cert using SHA256 but it signed with SHA1. Here's the command I used in the script: default_md = sha256. Anyway, I'm just wondering which version began supporting SHA256 or what's wrong with my command such that it signs with SHA1? Thanks again!
I am quite sure that SHA256 was in 0.9.8 too, but I don't know how much further back it was there.
