C++ (Cpp) encryptedKey Examples

Example #1

File: EcdsaProvider.cpp Project: Open-Transactions/opentxs

bool EcdsaProvider::ExportECPrivatekey(
    const OTPassword& privkey,
    const OTPasswordData& password,
    crypto::key::EllipticCurve& asymmetricKey) const
{
    std::unique_ptr<proto::Ciphertext> encryptedKey(new proto::Ciphertext);

    EncryptPrivateKey(privkey, password, *encryptedKey);

    return asymmetricKey.SetKey(encryptedKey);
}

Example #2
