This page is your complete resource for checksum generation and verification. Generate SHA256, SHA512, SHA1 and MD5 hashes instantly and learn how to verify file integrity securely. All calculations run locally in your browser.

What is a checksum?

A checksum is a cryptographic hash value used to verify file integrity. If two checksum values match exactly, the file has not been altered or corrupted. Checksums are widely used to verify software downloads, ISO files, backups and system updates.

Supported Algorithms

SHA256

Secure and widely recommended for modern verification. Use SHA256 Generator

SHA512

Higher security level within the SHA-2 family. Use SHA512 Generator

SHA1

Legacy algorithm used for compatibility. Use SHA1 Generator

MD5

Commonly used for file verification but not secure for passwords. Use MD5 Generator

How to verify SHA256 on Windows

You can verify a SHA256 checksum using Windows Command Prompt. See the complete step-by-step guide: How to verify SHA256 on Windows
