Sign Ed25519
Ed25519 is a widely adopted digital signature algorithm known for its strong security and efficiency. Signing with Ed25519 ensures data integrityAssurance that the data stored in the ledger has not been tampered with or altered in any unauthorized way., authenticity, and non-repudiation. When signing with Ed25519, a private key generates a digital signature that can be verified with the corresponding public key. This process guarantees that the data has not been tampered with and originated from the private key's holder.
Example Code
- Rust
- Typescript (Node.js)
- Python
- Create a
StrongholdSecretManagerwith theSTRONGHOLD_PASSWORDandMNEMONICvariables in your.envfile.
- Use the
SecretManagerto sign theFOUNDRY_METADATAmessage as bytes using theStrongholdAdapter.sign_ed25519()function.
- Hash the public key to get the address using the
hex_public_key_to_bech32_address()function.
- Create a
StrongholdSecretManagerwith theSTRONGHOLD_PASSWORDandMNEMONICvariables in your.envfile.
- Use the
SecretManagerto sign theFOUNDRY_METADATAmessage as bytes using theSecretManager.signEd25519()function.
- Hash the public key to get the address using the
