Security Information
MD5 & SHA-1: Cryptographically broken, use only for non-security purposes like checksums.
SHA-256/384/512: Secure for cryptographic purposes and recommended for security-sensitive applications.
Privacy: All processing happens in your browser. No data is sent to any server.
Algorithm Comparison
| Algorithm | Output Size | Security | Use Case |
|---|---|---|---|
| MD5 | 128 bits (32 hex) | Broken | Checksums, file verification |
| SHA-1 | 160 bits (40 hex) | Deprecated | Legacy systems |
| SHA-256 | 256 bits (64 hex) | Secure | General cryptographic use |
| SHA-384 | 384 bits (96 hex) | Secure | High security applications |
| SHA-512 | 512 bits (128 hex) | Secure | Maximum security |

How Hash Generation Works
Hashes are deterministic outputs derived from input data using a one-way function.
Input
Provide text or select a file.
Choose algorithm
Pick MD5, SHA-1, or SHA-2 family algorithm.
Generate
The tool computes the digest locally and displays it.
Verify
Compare the digest with known values to confirm integrity.
Typical Use Cases
File integrity
Ensure downloads and backups haven't been corrupted.
Checksums for releases
Publish hash sums for release artifacts to allow verification.
Quick developer checks
Use hashes in scripts and CI to detect unexpected changes.
Understanding Hash Functions
What hashing is, common algorithms, and security considerations
What is a hash?
A hash function maps input data of arbitrary size to a fixed-size digest. It is fast and deterministic.
Common Algorithms
MD5 (legacy), SHA-1 (deprecated for security), SHA-256/SHA-512 (recommended) used across tooling and releases.
Collision Resistance
Stronger algorithms reduce collision risk. Avoid MD5/SHA-1 for security-sensitive uses due to known collisions.
Use Cases
Checksums for downloads, deduplication, quick equality checks, and CI integrity checks are common applications.
Security Considerations
Hashes are not passwords. For authentication, use keyed hashing or password hashing algorithms (bcrypt, Argon2).
Verifying Integrity
Compare published checksums with generated digests to ensure file authenticity and integrity.
