Hash
Working with hashes or need to verify data integrity? These online hashing tools make it easy to generate hash values, calculate checksums, and verify data without installing extra software.
Whether you’re testing an API, comparing files, or working with MD5, SHA-256, SHA-512, and other hash algorithms, you’ll find practical utilities for getting the job done right in your browser.
Generate a SHA-224 digest from text or encoded bytes. Choose hex or Base64 output, or test HMAC-SHA224 with a key.
Generate SHA-512 hashes from text, switch between hex and Base64 output, or enable HMAC-SHA512 for keyed digests.
Generate Keccak-256 hashes from text with UTF-8, Hex, or Base64 input. View live results, use HMAC mode, and copy Hex or Base64 output.
Calculate CRC checksums from text using UTF-8 input. View results in lowercase or uppercase hex or Base64, with live mode and one-click copying.
Generate SHA256 hashes from text or strings online. Choose UTF-8, Hex or Base64 input, switch to HMAC-SHA256, and copy the result instantly.
Generate MD5 hashes from text with flexible input encodings, HMAC support, and Hex or Base64 output.
