About Hash Algorithms
MD5: 128-bit hash function. Fast but not cryptographically secure. Commonly used for file integrity verification and checksums.
SHA-1: 160-bit hash function. Deprecated for security applications due to collision vulnerabilities. Still used for git commits.
SHA-256: 256-bit hash from the SHA-2 family. Widely used and considered secure for most applications.
SHA-384: 384-bit hash from the SHA-2 family. Provides higher security than SHA-256.
SHA-512: 512-bit hash from the SHA-2 family. Maximum security in the SHA-2 family, used for sensitive data.

Common Use Cases
File Verification: Compare calculated hashes with published checksums to verify file integrity and authenticity.
Data Integrity: Ensure files haven't been corrupted during transfer or storage by comparing hash values.
Duplicate Detection: Identify duplicate files by comparing their hash values, even if filenames differ.
Password Storage: Hash passwords before storing them in databases (use SHA-256 or stronger with salt).
Digital Signatures: Create unique fingerprints of documents for verification and non-repudiation.

About File Comparison
Hash-Based Comparison: Compares files by calculating cryptographic hashes for both files. If all hashes match, the files are identical at the binary level.
Integrity Verification: Perfect for verifying that a downloaded file matches the original, or confirming two files are exactly the same.
Byte-Perfect Accuracy: Even a single bit difference will result in completely different hash values, ensuring precise comparison.
