Subject: [LTP] [PATCH 22/33] keyctl29: Test KEYCTL_PKEY_QUERY on public key
Date: Wed, 02 Sep 2026 13:04:37 +0200 [thread overview]
Message-ID: <20260902-keyctl_coverage-v1-22-d29dfa2ebcef@suse.com> (raw)
In-Reply-To: <20260902-keyctl_coverage-v1-0-d29dfa2ebcef@suse.com>
From: Andrea Cervesato <andrea.cervesato@suse.com>
Test KEYCTL_PKEY_QUERY operation on an RSA-2048 X.509 public key
certificate: verify key_size is 2048, supported_ops contains
ENCRYPT and VERIFY, and max_enc_size/max_sig_size are 256.
