I'm ok with not supporting SHA-1, although adding it would not be a security
issue. It is blocked by default now, but it can be re-enabled, and SHA-1 in
general is still available in the JDK.
I'm fine with adding support for SHA-224 and SHA-3 as part of this issue. You
can add support for all the algorithms that we have the underlying crypto
support for.
