SHA256-IP, Hardware SHA-2 Hash

FIPS-compliant SHA-256 hashing in pure logic for integrity, signing, and authentication.

 

SHA256-IP produces 256-bit digests over 512-bit message blocks with a simple streaming or register interface. It is designed to run alongside networking and storage IP to authenticate headers, verify firmware, or build message authentication flows.

 

 

 

Highlights

  • SHA-256 per the SHA-2 family
  • 512-bit message block processing with 256-bit digest output
  • Simple control for message start, update, and finalize
  • Streaming interface option for continuous data
  • Reference demo with timing capture and vector verification

 

 

 

Why Macnica?

  • Hash placement patterns for packets, logs, and firmware images
  • Co-design with AES-GCM and TLS1.3-IP when full message authentication is required
  • Known-good test vectors and scripts for rapid validation
  • Resource and timing tuning on Agilex platforms
