kernel: add support for authenc(hmac(md5),*) on safexcel
This patch adds support for the following AEAD ciphersuites: - authenc(hmac(md5),cbc(aes)) - authenc(hmac(md5),cbc(des))) - authenc(hmac(md5),cbc(des3_ede)) - authenc(hmac(md5),rfc3686(ctr(aes))) These algorithms are used mainly for backward compatibility with some older equipment. This is enhanced version of the patch found in the mtk-openwrt-feeds repo. All cipher suites were tested using test vectors on the MediaTek MT7981, MT7986, and MT7988.

Subject: [PATCH 2/2] crypto: safexcel - Add support for authenc(hmac(md5),*)
|
||||
suites
|
||||
|
||||
This patch adds support for the following AEAD ciphersuites:
|
||||
- authenc(hmac(md5),cbc(aes))
|
||||
- authenc(hmac(md5),cbc(des)))
|
||||
- authenc(hmac(md5),cbc(des3_ede))
|
||||
- authenc(hmac(md5),rfc3686(ctr(aes)))
|
||||
|
||||
The first three ciphersuites were tested using testmgr and the recently
|
||||
sent test vectors. They passed self-tests.
|
||||
|
||||
This is enhanced version of the patch found in the mtk-openwrt-feeds repo.
