Hello Herbert, back in 2019 you wrote that akcipher is still in a state of flux and not ready to be exposed to userspace via AF_ALG [1]. Has this changed since then? I am asking because I am implementing another driver [2] for a device which allows for signing messages with an ECDSA private key securely stored inside the device, and Greg asks again [3] for this to be exposed to userspace via a dedicated kernel API, instead of debugfs. Back in 2019 when we needed this for the turris-mox-rwtm driver, I implemented it via debugfs because akcipher was not ready. Thanks.
