How do I choose a cryptographic algorithm?

Choosing a cryptographic algorithm depends on your specific needs, such as security level, performance, and compatibility. What are you planning to use it for?

I'm developing a secure messaging app. What should I consider?

For a secure messaging app, consider algorithms that provide strong encryption, like AES for symmetric encryption and RSA or ECC for asymmetric encryption. You should also think about key management.

What about performance? Does it matter?

Yes, performance is crucial, especially for real-time applications. AES is generally faster than RSA, so for encrypting messages, AES is often preferred.

Are there any specific standards I should follow?

Yes, you should look into standards like NIST SP 800-175 for cryptographic algorithms and ensure compliance with relevant regulations.
