Verify offchain attestation
Verify the authenticity and integrity of offchain attestations by checking their cryptographic signatures against the original data.
Drag and drop an attestation file here to verify it
Get file hash
Generate cryptographic hashes (SHA-256) for files to create unique fingerprints that can be used in attestations or for data integrity verification.
Drop a file here to get its hash
The hashing is done locally in your browser. Your file is not uploaded anywhere.
Offchain multi-timestamp
Create tamper-proof timestamps for multiple pieces of data using Merkle tree technology, providing cryptographic proof of when information existed.
Enter multiple offchain attestation UID's on separate lines
Example:
0x1234...
0x5678...
0xabcd...
