Plesk can be used to generate CSR's for SSL certificates but uses SHA-1 as the hash by default. Browsers will soon prefer SHA-2 certificates, so I'd like to start using that for CSR hashing.

How can I generate CSR's using SHA-2 (i.e. with what would be the -sha256 flag in OpenSSL) using Plesk?

  • The SHA-224, SHA-256, SHA-384 and SHA-512 functions are colloquially known as "SHA-2", so "SHA-2" is not one function, but a family of four hash functions. Source: StackOverflow so is there an option to use 224, 256 384 or 512? as these are SHA-2 compatible hashs – Simon Hayter Oct 16 '14 at 19:43
  • That's pretty much my question exactly. – Andrew Lott Oct 16 '14 at 20:47
