Provide support for SHA256 Self Signed Certificates
Currently, creating Self Signed Certificates in IIS only allows you to create SHA1 algorithm Self Signed Certificates. However, SHA1 is being deprecated in favor of SHA256, therefore, IIS Manager should support creating SHA256 Self Signed Certificates instead (or prompt as to whether you wish to create an SHA1 or SHA256 Self Signed Certificate)

IIS Manager for IIS 10 seems to have resolved this. If you have to use an older IIS release, switch to PowerShell, https://gallery.technet.microsoft.com/scriptcenter/Self-signed-certificate-5920a7c6

I don't know if you can change the title but from I understand you're asking the IIS team for an update tof he tooling to allow the creation of self signed certificates that use the SHA256 or even SHA512 signature algorithm. The web server itself can use SHA256 certificates just fine - haven't tried SHA512 though.
So the title should be 'Provide tooling to create SHA256 Self Signed Certificates'
SHA1 is deprecated in favor of SHA2. Not only SHA256, but also SHA512 support is in need
