SHA256 is a full NIST standard.
Its just suspect because it is based on the SHA1/Md5 technology amd
likely to be replaced

Is this really the case, or is SHA-256 a sort of generic
placeholder for "something better than SHA-1"? I haven't paid
very much attention to what the cryptographers have been
saying about this, but it doesn't seem clear to me that
SHA-256 has been settled on as The short term replacement. Or has it?
