RFC 8009 enctypes use different crypt formulae than previous Kerberos 5 encryption types. Section 1 of RFC 8009 explains the reason for this change: > The new types conform to the framework specified in [RFC3961], > but do not use the simplified profile, as the simplified profile > is not compliant with modern cryptographic best practices such as > calculating Message Authentication Codes (MACs) over ciphertext > rather than plaintext. Add new .encrypt and .decrypt functions to handle this variation. The new approach described above is referred to as Encrypt-then-MAC (or EtM). Hence the names of the new functions added here are prefixed with "krb5_etm_". A critical second difference with previous crypt formulae is that the cipher state is included in the computed HMAC. Note however that for RPCSEC, the initial cipher state is easy to compute on both initiator and acceptor because it is always all zeroes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
