Sorry, I forgot to include also a link to INSTALL.md I am linking the preview from PR#12109 again, as it has been improved to leverage Markdown formatting to be more readable: https://github.com/openssl/openssl/blob/be101175badd30402d2e480a79e98ade1343cbfd/INSTALL.md#installing-openssl Same caveat as before: at some point the link above will likely be broken once the PR is merged, but the updated INSTALL.md file will be available at https://github.com/openssl/openssl/blob/master/INSTALL.md#installing-openssl On Sun, 28 Jun 2020 at 16:56, Nicola Tuveri <nic.tuv@xxxxxxxxx> wrote: > > Hello and welcome! > > > On my system (Debian 10 - Buster) is OpenSSL installed with Version 1.1. > > Now, I want to install OpenSSL 3.x, but which is the best way for that? > > > > Deinstall the old one, or? > > First, keep in mind that 3.x is still in alpha development stage, so > using it as the system-wide library is not at all recommended. > > Even after 3.0 will be released officially, replacing the system wide > installation of OpenSSL provided by your Linux distribution is a very > risky business, as many of the required and optional binary packages > the distribution provides are depending on the version of `libcrypto` > and `libssl` shipped within the official OpenSSL packages from your > distribution. > > The recommended thing to do when you want to build applications from > sources to use a different version of OpenSSL than what is shipped > with your distribution is to have a custom installation of OpenSSL > (somewhere outside of your linker default path). > > You can read more about it on the NOTES.UNIX file in your source > tarball, or at https://github.com/openssl/openssl/blob/OpenSSL_1_1_1-stable/NOTES.UNIX > . > > Note the link above is from the 1.1.1 stable branch, as in master soon > it will likely be replaced with a markdown version of the same file > (PR #12109): you can see a preview of the markdown version of it at > https://github.com/openssl/openssl/blob/be101175badd30402d2e480a79e98ade1343cbfd/NOTES-Unix.md > but beware this link is likely going to be broken at some point after > the PR is merged (but at that point you will be able to find the same > file in `master`). > > > Hope this helps! > > > Best regards, > > Nicola Tuveri
