$ openssl enc -ciphername [options] You can obtain an incomplete help message by using an invalid option, eg. -help. Cipher alogorithms . To get a list of available ciphers you can use the list -cipher-algorithms command $ openssl list -cipher-algorithms The output gives you a list of ciphers with its variations in key size and mode of operation.
As of OpenSSL 1.1.1, providing subjectAltName directly on command line becomes much easier, with the introduction of the -addext flag to openssl req (via this commit).. The commit adds an example to the openssl req man page:. Example of giving the most common attributes (subject and extensions) on the command line: openssl req -new -subj "/C=GB/CN=foo" \ -addext "subjectAltName = DNS:foo.co.uk Connection error when using EC client certificate with
