**MD5 and SHA1 Hash algorithm replacement** #10198
Description
Replace mentions of using MD5 or SHA1 with SHA256, SHA284, or SHA512. This involves:
- Conceptual documentation.
- Reference documentation. This includes a note in the MD5 and SHA1 documentation that it is not recommended, and that the suggested replacement is SHA256, etc.
- Code. Usage of MD5 or SHA1 should be replaced except for code for the MD5 and SHA1 types in the managed reference documentation.
