This native module exposes java functions and react methods that deal with the generation and management of ECDSA keys. To generate Ethereum keys, the native module uses Web3j and BouncyCastle libraries. The EC key pair is generated using the secp256k1 EC.

This react method can be used to compress the EC Public key.

• pubKey: EC Public Key (in Big Integer format) to be compressed.

Compressed EC public key in String format.

This react method can be used to derive ETH address from a given public key.

• publicKey: EC Public Key (in Big Integer format).

ETH address in String format

This react method can be used to generate a keystore JSON file for a given EC Key pair.

• walletPassword: String password to protect the kyestore file.
• storagePath: Directory location (in String format) to store the keystore file.
• ecKeyPair: EC Key pair to generate keystore file for.

Filename (in String format) of the newly generated Keystore file.

This react method can be used to decrypt a keystore wallet and derive the credentials.

• keystorePath: File path of the keystore JSON, to load credentials from.
• walletPassword: Password (in String format) of the keystore JSON file.

Returns the EC key pair in the org.web3j.crypto.Credentials format.

This method generates a BIP39 seed phrase (mnemonic) which can be used to derive EC key pair.

Not required.

Mnemonic (in String format).

This method is used to generate EC key pair from the mnemonic (generated using the generateBIP39Mnemonic function).

• mnemonic: Seed phrase (in String format).
• password: Password (in String format) to create EC key pair.

EC key pair (in the format org.web3j.crypto.ECKeyPair).

This method is used to convert the format of keypair from Bouncycastle's ECKeyPair to Android's KeyPair.

• ecKeyPair: EC key pair (in the format supported by bouncycastle).

KeyPair, in the format supported by Android keystore.

This React method can be used to generate a password protected keystore wallet from a given seed phrase.

• mnemonic: Seed phrase (in String format).
• password: Password (in String format) to encrypt the file.
• destinationDirectory: Directory path (in String format) to save the keystore JSON file in.

Filename (in String format) of the newly created keystore JSON file.

This react method can be used to load EC key pairs from an externally stored keystore JSON file, provided the file path in user's mobile device.

• password: Password (in String format) to decrypt the file.
• filePath: File path (in String format) of the keystore JSON file.

Nothing.
