Subject: [PATCH v4 3/4] blk-crypto: Add LEA-256-XTS blk-crypto support
Date: Fri, 30 Jun 2023 14:03:22 +0900	[thread overview]
Message-ID: <20230630050323.984216-4-letrhee@nsr.re.kr> (raw)
In-Reply-To: <20230630050323.984216-1-letrhee@nsr.re.kr>

Add LEA-256-XTS blk-crypto support

LEA is a 128-bit block cipher developed by South Korea.

LEA is a Korean national standard (KS X 3246) and included in the
ISO/IEC 29192-2:2019 standard (Information security - Lightweight
cryptography - Part 2: Block ciphers).

Enable the LEA to be used in block inline encryption. This can be
used via blk-crypto-fallback, when using the "inlinecrypt" mount
option in fscrypt.
