PIPELINE Hashing & Validation Intermediate 2 steps

Hash text and verify with CRC32 checksum

When verifying data integrity across systems, having both a strong hash (SHA-256) and a lightweight checksum (CRC32) lets you catch different classes of corruption. The first node hashes the input with SHA-256; the second computes a CRC32 checksum of that hash for compact verification.

What it solves

Compute both a cryptographic SHA-256 hash and a CRC32 checksum for data integrity verification.
