Cryptographic Hash Generator & Checksum Verifier
Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic digests for text strings and binary files. Verify file integrity and checksum matches.
Cryptographic Hash Function Algorithms
A cryptographic hash function maps arbitrary binary data to a fixed-size bit string. It is deterministic, one-way (irreversible), and collision-resistant.
Algorithm Comparison
- MD5 (128-bit): Legacy digest algorithm (FIPS 180 deprecated). Fast for non-cryptographic checksum verification.
- SHA-1 (160-bit): Legacy algorithm susceptible to collision attacks (SHAttered).
- SHA-256 (256-bit): Modern FIPS 180-4 standard used in TLS, Bitcoin, and security signatures.
- SHA-512 (512-bit): High-security 512-bit digest optimal on 64-bit architecture CPUs.
