In this first step, you need to generate the Block Hash as you have done earlier. Use the Bitcoin Hash Verification Tool to generate/verify the hash of a block. We will use this block hash as a message to encrypt in the following steps.
We need to generate a Public-Private keypair for us to encode and decode the message. We will encode the message using the public key and then decrypt it using the private key to get the original data back. Use the form below to generate your public and private keys. Private key is hidden from being displayed here.
In this step, we will encrypt a message using the public key that we've generated in the previous step. Use the form below to encrypt your message.
In this step, we will decrypt the message using the private key. Use the form below to decrypt the message. Please note if you are using a different key than the one last generated above, the decryption will not work.
