Question 1

How do I use Dongle for AES encryption in Go?

Accepted Answer

Create a cipher with cipher.NewAesCipher, set the key, IV, and padding mode, then chain methods like dongle.Encrypt.FromString('text').ByAes(c).ToHexString(). Refer to the symmetric encryption example in the README for details.

Question 2

Dongle vs Go's standard crypto package – which should I use?

Accepted Answer

Dongle offers a simpler, unified API for common tasks, reducing boilerplate, while the standard library provides lower-level control and broader algorithm support, including newer ones like ECC. Choose Dongle for developer convenience and the standard library for fine-grained control.

Question 3

Does Dongle support SHA-3 or other recent hash algorithms?

Accepted Answer

No, the README only mentions MD5 and SHA variants, so it likely doesn't include SHA-3 or other modern hashes, which might be a limitation for applications requiring up-to-date cryptographic standards.

Question 4

How do I generate RSA keys with Dongle?

Accepted Answer

Dongle doesn't include built-in key generation; you need to generate keys externally (e.g., using Go's crypto/rsa) and set them via SetPublicKey or SetPrivateKey, as shown in the asymmetric encryption examples.

Question 5

Is Dongle production-ready for high-security applications?

Accepted Answer

With 100% test coverage and community recognition, it's reliable for many use cases, but for certified or high-assurance environments, consider specialized libraries that meet regulatory standards like FIPS.

Question 6

What's the performance impact of using Dongle compared to direct crypto calls?

Accepted Answer

The abstraction layer may introduce slight overhead, but for most applications, the trade-off in reduced code complexity and errors is worth it; benchmark for critical paths if performance is a concern.
