+CRC32 (Cyclic Redundancy Check 32-bit) Hash Algorithm
+
+This module implements the CRC32 hash algorithm, a non-cryptographic hash function
+widely used for error detection and data integrity verification.
+
+CRC32 is commonly used in:
+- ZIP file format for data integrity
+- Ethernet frame check sequences
+- PNG image format for chunk verification
+- Gzip compression
+
+The algorithm uses the IEEE 802.3 polynomial (0xEDB88320 in reversed bit order)
+and produces a 32-bit hash value.
+
+Note: CRC32 is NOT suitable for cryptographic purposes. It's designed for
+error detection, not security. For cryptographic hashing, use SHA-256 or similar.
+
