Self-signed certificate generator (PowerShell) SHA-2? RRS feed

  • Question

  • Hi,

    The Doc for this script lists only the following Signature Algorithms:

    Currently signature algorithms are limited to: 
        MD5 
        SHA1 
        SHA256 
        SHA384 
        SHA512

    But I found on another forum that

    Trying to access a secure website that only uses SHA-1 encryption.  SHA-1 encrypted websites with certificates valid beyond Jan. 1, 2017 are marked as definitely insecure with Red HTTPS slash.  Such websites need to update their security certs to SHA-2.

    I notice that the script was last updated 9/11/16, which would predate this 1/1/17 change to the SHA-2 requirement.

    Apparently I need to generate a new certificate, but it seems this script will not generate one with the currently-required encryption level. Is there a way to do this? Can I use one of the other supported signature algorithms? Suggestions?

    Thank you very much,

    David Baldwin

    If you are talking about accessing public web sites then there is no way to change the client to make the site use a valid SSL cert.
