A cryptographic hash is a fixed-size string generated from input data using a mathematical algorithm. It acts as a unique fingerprint for data - even a tiny change in the input produces a completely different hash, making it ideal for verifying file integrity and data authenticity.
For general file verification, SHA-256 is recommended as it offers strong security and is widely used. MD5 and SHA-1 are faster but considered cryptographically weak for security purposes - use them only for non-security checksums. SHA-512 provides the highest security level.
