Secure Hash Algorithm 256 IP Core

A universal solution that effectively accelerates the SHA2-256 hash function conforming with FIPS PUB 180-4 is the SHA2-256 bridge to APB, AHB, and AXI bus. It has two modes for computing message digests: 256-bit and 224-bit. A message length of up to 264 +/- 1 bit may be entered. It also natively supports the SHA2-256 HMAC (Keyed-Hash Message Authentication Code), a cryptographic function defined in RFC 2104. This depends on the core settings. This IP is appropriate for secure communication in general as well as for verifying data integrity and authenticity in digital signature methods. It may also be applied to speed up calculations related to cryptocurrencies.
