Subject: [PATCH 09/10] sa2ul: Add 3DES ECB & CBC Mode support
Date: Tue, 18 Jun 2019 17:38:42 +0530 [thread overview]
Message-ID: <20190618120843.18777-10-j-keerthy@ti.com> (raw)
In-Reply-To: <20190618120843.18777-1-j-keerthy@ti.com>
Triple DES (3DES), officially the Triple Data Encryption Algorithm
(TDEA or Triple DEA), is a symmetric-key block cipher, which applies
the DES cipher algorithm three times to each data block
Add 3DES ECB(Electronic code book) & CBC(Cipher Block Chaining)
Mode support.
