decrypt :: (ByteArrayAccess password, ByteArray privateKey) => EncryptedKey -> password -> Maybe privateKey Source #
Decrypt Ethereum private key.
Typically Web3 Secret Storage is JSON-encoded. EncryptedKey data type has FromJSON instance
to helps decode it from JSON-encoded string or file.
let decryptJSON pass = flip decrypt pass <=< decode
encrypt :: (ByteArray privateKey, ByteArrayAccess password, MonadRandom m) => privateKey -> password -> m EncryptedKey Source #
Encrypt Ethereum private key.
let encryptJSON pass key = encode $ encrypt key pass
