QUERY · ISSUE

How do I generate an EC private key with the NISTP256 curve (aka secp256r1, or prime256v1) , and using the private key to generate a public key serialized to bytes in the ANSI X9.62/X9.63 Uncompressed Point format on ESP 32?

Otherwise running the tests can take a long time when the server is a slow target (RP2040 takes 23 seconds for a handshake when using 4096-bit RSA).

Assessment

Q Qwen · medium

The query asks specifically about generating EC private keys with NISTP256 curve and serializing public keys in ANSI X9.62 format on ESP32. The candidate PR (#13332) is about reducing RSA certificate sizes for tests and mentions adding documentation for elliptic curve key/cert generation in tests/README.md. While both items involve elliptic curve cryptography and key generation, the PR focuses on RSA certificate optimization for tests, not the specific EC key generation and serialization methods the user needs. The PR may contain some relevant documentation about EC keys, but it doesn't directly resolve the user's question about how to perform these specific operations.

Suggested action

Keep both items open. The PR may provide useful context or documentation about EC key generation that could help answer the query, but it doesn't directly address the specific serialization format question.
