Decryption provider using ethereum private keys.
npm install @requestnetwork/epk-decryptionEthereum Private Key Decryption Provider.
@requestnetwork/epk-decryption is a typescript library part of the Request Network protocol.
Implementation of the decryption provider from the private keys.
The decryption provider is used to make decryption in the Request Network Protocol (e.g.: see Transaction Manager).
It uses the Request Network Protocol concept of Identity described in the request logic specification.
``bash`
npm install @requestnetwork/epk-decryption
`javascript
import { EncryptionTypes, IdentityTypes } from '@requestnetwork/types'
import EthereumPrivateKeyDecryptionProvider from '@requestnetwork/epk-decryption'
const decryptionParametersExample: EncryptionTypes.IDecryptionParameters = {
key: '0xc87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3',
method: EncryptionTypes.METHOD.ECIES,
};
// Identity from the previous signature parameter
const identityExample: IdentityTypes.IIdentity = {
type: IdentityTypes.TYPE.ETHEREUM_ADDRESS,
value: '0x627306090abab3a6e1400e9345bc60c78a8bef57'
};
// Construct the provider with a
const decryptionProvider = new EthereumPrivateKeyDecryptionProvider(decryptionParametersExample);
// can list the identity usable
const listOfAvailableIdentity = decryptionProvider.getAllRegisteredIdentities(); // [identityExample]
// can decrypt data with identity
const dataToDecrypt = "02....";
const decryptedData = await decryptionProvider.decrypt(dataToDecrypt, identityExample); // "Decrypted data..."
// can add a new decryption parameters
decryptionProvider.addDecryptionParameters({method: EncryptionTypes.METHOD.ECIES, key: ...});
// can remove a decryption parameters from its identity
decryptionProvider.removeRegisteredIdentity({type: IdentityTypes.TYPE.ETHEREUM_ADDRESS, value: ...});
// can remove all decryption parameters
decryptionProvider.clearAllRegisteredIdentities();
