Generate secure checksums and hash values for your text or data using industry-standard algorithms
The Checksum Calculator is a powerful online utility that allows users to generate hash values (also known as checksums or digests) for any given text or data. By using standard cryptographic and non-cryptographic hash algorithms, the tool helps ensure data integrity, authenticity, and verification.
Whether you’re a developer validating file transfers, a cybersecurity analyst comparing hash values, or an eCommerce platform verifying user-submitted data, this calculator is built to provide accurate and reliable results across multiple algorithms.
Multiple Hash Algorithms:
SHA-1
SHA-256
SHA-384
SHA-512
MD5
CRC32
xxHash
Base64 Encoding
Mixed Output Mode: Generate results from all supported algorithms at once.
Real-time Hashing: Instantly generates checksums as you enter text.
Supports Any Data Type: Text, binary data, passwords, source code, or files (optional with file support).
Copy-Friendly Output: Easily copy hash results for use in development, verification, or documentation.
Stateless and Secure: No data is stored or transmitted — processed entirely in-browser (if applicable).
Data Integrity Validation: Detect accidental or intentional data corruption.
File Verification: Ensure downloaded or transferred files haven’t been tampered with.
Password Storage & Authentication: Store secure hashes of passwords instead of raw data.
Efficient Debugging: Compare hashes quickly during development or testing.
Offline Capability: Can be implemented to work fully offline for sensitive use cases.
Securely store hashed passwords
Detect changes in code, scripts, or config files
Validate API payloads or response bodies
Verify downloaded ISO or software checksum values
Track data corruption in file transfers or backups
Use SHA and MD5 hashes to detect tampering
Maintain hash databases of known malware signatures
Verify uploaded product data integrity
Prevent manipulation of discount codes, user-generated content
Compare datasets

A checksum is a unique value calculated from a set of data to verify its integrity. It helps ensure the data has not been altered.
Checksums are often simple and fast for error detection, while cryptographic hashes (like SHA-256) are stronger and secure against tampering.
It supports SHA-1, SHA-256, SHA-384, SHA-512, MD5, CRC32, xxHash, and Base64 encoding.
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function widely used for data integrity and digital signatures.
MD5 is fast but no longer secure for cryptographic purposes. It’s vulnerable to collisions and should only be used for file verification.
No. The calculator processes all data in-browser and does not store, transmit, or log any input.
xxHash is a very fast non-cryptographic hashing algorithm useful for checksumming large files or blocks of data.
