What do people build with it?

USE CASE 1

Encrypt sensitive user data in a Rust web service using a public/private key pair.

USE CASE 2

Digitally sign a software release so users can verify it wasn't tampered with.

USE CASE 3

Build a secure communication system that follows standard PKCS1v1.5 or OAEP formats.

USE CASE 4

Verify a signature created with PSS to confirm authenticity of a message.

What is it built with?

Copy-paste prompts

Prompt 1

Show me how to generate a public/private key pair and encrypt data with this Rust RSA library.

Prompt 2

Help me sign and verify a file using PSS with this library.

Prompt 3

Explain the difference between PKCS1v1.5 and OAEP encryption modes in this crate.

Prompt 4

Walk me through compiling this library in optimized mode so key generation isn't slow.
