SHA-512/224 generator
What SHA-512/224 means
NIST defines SHA-512/224 as SHA-512 with distinct initialization constants and only the top 224 bits emitted (56 hex chars). Internals still run the SHA-512 compression function—useful when you want SHA-512-class engineering but a SHA-224-sized field.
Why not plain SHA-224?
They differ in IV and width pipeline—interop tests must name the exact variant. Pick whichever your standard mandates; never truncate hex strings manually and assume equivalence.
Cross-check
When migrating TLS configs or VPN suites, confirm both endpoints advertise the same truncated SHA-512 mode labels.
