Frequently Asked Questions
Which cryptographic hash algorithms are supported?
Calculate SHA-256, SHA-512, SHA-384, SHA-1, MD5, and CRC32 checksums as well as HMAC secret key signatures.
Can I verify file checksums without uploading to a server?
Yes. Drag and drop any software release or binary file. Checksums are computed locally in your browser memory via the Web Cryptography API.
What is HMAC used for?
Hash-based Message Authentication Codes (HMAC) combine cryptographic hash functions with secret keys to verify data authenticity and tamper-resistance in APIs.
