• share-key: Share public key
• fetch-key: Fetch a public key by key ID

Options

• infile: Input file to be signed or verified.
• --out: Output file for the signed file (only applicable for the sign command).
• --password: Password for the private key (required for the sign command).
• --namespace: Namespace for key derivation (default: default_namespace).
• --counter: Counter for key derivation (default: 0).
• --showpk: Show the public key after signing (only applicable for the sign command).
• --algorithm: Specify the SPHINCS+ algorithm to use (default: shake_256f).
• --bootstrap: Bootstrap nodes for the Kademlia network.
• --port: Port number for the Kademlia network (default: 8470).
• --run-forever: Keep the Kademlia server running indefinitely.

Examples

• Sign a file:

• Verify the signature of a file:

sign_everywhere verify infile.txt signature.txt public_key

• Run the Key server:

sign_everywhere  [ --bootstrap=node1,node2,node3 ] --run-forever

• Publish Public Key ( Take local key server as an example )

sign_everywhere --port 8471 --bootstrap="127.0.0.1:8470" share-key [public_key] [yourname]

Public Key ID: [keyid]
Fingerprint: [fingerprint]
Public Key: [public_key]

sign_everywhere --port 8471 --bootstrap="127.0.0.1:8470" fetch-key [keyid]
