-+@section Argon2
-+
-+Argon2 is a key derivation function used by LUKS2 in order to derive encryption
-+keys from a user-provided password. GRUB imports the official reference
-+implementation of Argon2 from @url{https://github.com/P-H-C/phc-winner-argon2}.
-+In order to make the library usable for GRUB, we need to perform various
-+conversions. This is mainly due to the fact that the imported code makes use of
-+types and functions defined in the C standard library, which isn't available.
-+Furthermore, using the POSIX wrapper library is not possible as the code needs
-+to be part of the kernel.
-+
-+Updating the code can thus be performed like following:
-+
-+@example
-+$ git clone https://github.com/P-H-C/phc-winner-argon2 argon2
-+$ cp argon2/include/argon2.h argon2/src/@{argon2.c,core.c,core.h,ref.c@} \
-+ grub-core/lib/argon2/
-+$ cp argon2/src/blake2/@{blake2-impl.h,blake2.h,blake2b.c,blamka-round-ref.h@} \
-+ grub-core/lib/argon2/blake2/
-+$ sed -e 's/UINT32_C/GRUB_UINT32_C/g' \

-+
-+Afterwards, you need to perform the following manual steps:
-+
-+@enumerate
-+@item Remove all includes of standard library headers, "encoding.h" and
-+ "thread.h".
-+@item Add includes <grub/mm.h> and <grub/misc.h> to "argon2.h".
-+@item Add include <grub/dl.h> and module license declaration to "argon2.c".
-+@item Remove the following declarations and functions from "argon2.h" and
-+ "argon2.c": argon2_type2string, argon2i_hash_encoded, argon2i_hash_raw,
-+ argon2d_hash_encoded, argon2d_hash_raw, argon2id_hash_encoded,
-+ argon2id_hash_raw, argon2_compare, argon2_verify, argon2i_verify,
-+ argon2d_verify, argon2id_verify, argon2d_ctx, argon2i_ctx, argon2id_ctx,
-+ argon2_verify_ctx, argon2d_verify_ctx, argon2i_verify_ctx,
-+ argon2id_verify_ctx, argon2_encodedlen.
-+@item Move the declaration of `clear_internal_memory()` in "blake2-impl.h" to
-+ "blake2b.c".
-+@item Remove code guarded by the ARGON2_NO_THREADS macro.
-+@item Remove parameters `encoded` and `encodedlen` from `argon2_hash` and remove
-+ the encoding block in that function.
-+@item Remove parameter verifications in `validate_inputs()` for
-+ ARGON2_MIN_PWD_LENGTH, ARGON2_MIN_SECRET, ARGON2_MIN_AD_LENGTH and
-+ ARGON2_MAX_MEMORY to fix compiler warnings.
-+@item Mark the function argon2_ctx as static.

-+
-+Statement of Purpose
-+
-+The laws of most jurisdictions throughout the world automatically confer
-+exclusive Copyright and Related Rights (defined below) upon the creator
-+and subsequent owner(s) (each and all, an "owner") of an original work of
-+authorship and/or a database (each, a "Work").
-+
-+Certain owners wish to permanently relinquish those rights to a Work for
-+the purpose of contributing to a commons of creative, cultural and
-+scientific works ("Commons") that the public can reliably and without fear
-+of later claims of infringement build upon, modify, incorporate in other
-+works, reuse and redistribute as freely as possible in any form whatsoever
-+and for any purposes, including without limitation commercial purposes.
-+These owners may contribute to the Commons to promote the ideal of a free
-+culture and the further production of creative, cultural and scientific
-+works, or to gain reputation or greater distribution for their Work in
-+part through the use and efforts of others.
-+
-+For these and/or other purposes and motivations, and without any
-+expectation of additional consideration or compensation, the person
-+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
-+is an owner of Copyright and Related Rights in the Work, voluntarily
-+elects to apply CC0 to the Work and publicly distribute the Work under its
-+terms, with knowledge of his or her Copyright and Related Rights in the
-+Work and the meaning and intended legal effect of CC0 on those rights.
-+
-+1. Copyright and Related Rights. A Work made available under CC0 may be
-+protected by copyright and related or neighboring rights ("Copyright and
-+Related Rights"). Copyright and Related Rights include, but are not
-+limited to, the following:
-+
-+ i. the right to reproduce, adapt, distribute, perform, display,
-+ communicate, and translate a Work;
-+ ii. moral rights retained by the original author(s) and/or performer(s);
-+iii. publicity and privacy rights pertaining to a person's image or
-+ likeness depicted in a Work;
-+ iv. rights protecting against unfair competition in regards to a Work,
-+ subject to the limitations in paragraph 4(a), below;
-+ v. rights protecting the extraction, dissemination, use and reuse of data
-+ in a Work;
-+ vi. database rights (such as those arising under Directive 96/9/EC of the
-+ European Parliament and of the Council of 11 March 1996 on the legal
-+ protection of databases, and under any national implementation
-+ thereof, including any amended or successor version of such
-+ directive); and
-+vii. other similar, equivalent or corresponding rights throughout the
-+ world based on applicable law or treaty, and any national
-+ implementations thereof.
-+
-+2. Waiver. To the greatest extent permitted by, but not in contravention
-+of, applicable law, Affirmer hereby overtly, fully, permanently,
-+irrevocably and unconditionally waives, abandons, and surrenders all of
-+Affirmer's Copyright and Related Rights and associated claims and causes
-+of action, whether now known or unknown (including existing as well as
-+future claims and causes of action), in the Work (i) in all territories
-+worldwide, (ii) for the maximum duration provided by applicable law or
-+treaty (including future time extensions), (iii) in any current or future
-+medium and for any number of copies, and (iv) for any purpose whatsoever,
-+including without limitation commercial, advertising or promotional
-+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
-+member of the public at large and to the detriment of Affirmer's heirs and
-+successors, fully intending that such Waiver shall not be subject to
-+revocation, rescission, cancellation, termination, or any other legal or
-+equitable action to disrupt the quiet enjoyment of the Work by the public
-+as contemplated by Affirmer's express Statement of Purpose.
-+
-+3. Public License Fallback. Should any part of the Waiver for any reason
-+be judged legally invalid or ineffective under applicable law, then the
-+Waiver shall be preserved to the maximum extent permitted taking into
-+account Affirmer's express Statement of Purpose. In addition, to the
-+extent the Waiver is so judged Affirmer hereby grants to each affected
-+person a royalty-free, non transferable, non sublicensable, non exclusive,
-+irrevocable and unconditional license to exercise Affirmer's Copyright and
-+Related Rights in the Work (i) in all territories worldwide, (ii) for the
-+maximum duration provided by applicable law or treaty (including future
-+time extensions), (iii) in any current or future medium and for any number
-+of copies, and (iv) for any purpose whatsoever, including without
-+limitation commercial, advertising or promotional purposes (the
-+"License"). The License shall be deemed effective as of the date CC0 was
-+applied by Affirmer to the Work. Should any part of the License for any
-+reason be judged legally invalid or ineffective under applicable law, such
-+partial invalidity or ineffectiveness shall not invalidate the remainder
-+of the License, and in such case Affirmer hereby affirms that he or she
-+will not (i) exercise any of his or her remaining Copyright and Related
-+Rights in the Work or (ii) assert any associated claims and causes of
-+action with respect to the Work, in either case contrary to Affirmer's
-+express Statement of Purpose.
-+
-+4. Limitations and Disclaimers.
-+
-+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
-+ surrendered, licensed or otherwise affected by this document.
-+ b. Affirmer offers the Work as-is and makes no representations or
-+ warranties of any kind concerning the Work, express, implied,
-+ statutory or otherwise, including without limitation warranties of
-+ title, merchantability, fitness for a particular purpose, non
-+ infringement, or the absence of latent or other defects, accuracy, or
-+ the present or absence of errors, whether or not discoverable, all to
-+ the greatest extent permissible under applicable law.
-+ c. Affirmer disclaims responsibility for clearing rights of other persons
-+ that may apply to the Work or any use thereof, including without
-+ limitation any person's Copyright and Related Rights in the Work.
-+ Further, Affirmer disclaims responsibility for obtaining any necessary
-+ consents, permissions or other rights required for any use of the
-+ Work.
-+ d. Affirmer understands and acknowledges that Creative Commons is not a
-+ party to this document and has no duty or obligation with respect to
-+ this CC0 or use of the Work.
