Subject: [PATCH] pkcs7: support EC-RDSA/streebog in SignerInfo
Date: Tue, 11 May 2021 17:47:44 +0300	[thread overview]
Message-ID: <20210511174744.4f3c6c59@msk1wst204> (raw)

Allow using EC-RDSA/streebog in pkcs7 certificates in a similar way
to how it's done in the x509 parser.

This is needed e.g. for loading kernel modules signed with EC-RDSA.
