[PATCH 4.14 020/217] crypto: talitos - reduce max key size for SEC1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christophe Leroy <christophe.leroy@xxxxxx>

commit b8fbdc2bc4e71b62646031d5df5f08aafe15d5ad upstream.

SEC1 doesn't support SHA384/512, so it doesn't require
longer keys.

This patch reduces the max key size when the driver
is built for SEC1 only.

Fixes: 03d2c5114c95 ("crypto: talitos - Extend max key length for SHA384/512-HMAC and AEAD")
