Function batch_sha256 

pub fn batch_sha256(inputs: &[&[u8]]) -> Vec<[u8; 32]>

Batch SHA256: Compute SHA256 for multiple independent inputs

Arguments

• inputs - Slice of byte slices to hash

Returns

Vector of 32-byte hashes, one per input (in same order)

Performance

• Small batches (< 4 items): Sequential (overhead not worth parallelization)
• Medium batches (4-7 items): Chunked sequential
• Large batches (≥8 items): Multi-core parallelization with Rayon

Optimizations

• Uses sha2 crate with “asm” feature for optimized assembly
• For large batches, leverages Rayon for multi-core parallelization
• AVX2 batch optimization available via crypto::avx2_batch module
