Stitched aes-128 and hmac-sha1 (encrypt-then-mac)

[pablo platt <pablo.platt@xxxxxxxxx>]

Hi,

Stitching aes-cbc with sha1 can result with x2 performance [1].

Is there support for stitched aes-128-hmac-sha1 encrypt-then-mac? This issue [2] says that only mac-then-encrypt is supported in OpenSSL.

Does this implement mac-then-encrypt and relevant [3]?

Is it possible to use the same code with just changing the order to achieve encrypt-then-mac?

How can I compile the Perl file to be used from a C program?
