The SANDstorm hash was accepted into the first round of the NIST hash function competition, but was not accepted into the second round.[2]
Architecture
The hash function has an explicit key schedule.[3] It uses an 8-bit by 8-bit S-box.[3] The hash function can be parallelized on a large range of platforms[which?] using multi-core processing.[4]
Both SANDstorm-256 and SANDstorm-512 run more than twice as slowly as SHA-2 as measured by cpb.[3][clarification needed]
