Subject: Test AEAD/authenc algorithms from userspace
Date: Tue, 31 May 2016 12:31:16 +0530	[thread overview]
Message-ID: <CAFXBA=kStufh3TDe=+qQYmd2tNCj9hgXLUKBeoZHBs2VxRBRbQ@mail.gmail.com> (raw)

Hi All,

How can we open socket of type "authenc(hmac(sha256),cbc(aes))" from
userspace program.I check libkcapi library. It has test programs for
GCM/CCM. There are 3 types of approaches to Authenticated Encryption,
Which of them is supported in crypto framework.

1) Encrypt-then-MAC (EtM)
     The plaintext is first encrypted, then a MAC is produced based on
the resulting ciphertext. The ciphertext and its MAC are sent
together.
2) Encrypt-and-MAC (E&M)
     A MAC is produced based on the plaintext, and the plaintext is
encrypted without the MAC. The plaintext's MAC and the ciphertext are
sent together.

3) MAC-then-Encrypt (MtE)
     A MAC is produced based on the plaintext, then the plaintext and
MAC are together encrypted to produce a ciphertext based on both. The
ciphertext (containing an encrypted MAC) is sent.


Regards
Harsh Jain
