-Signed wheel files
-------------------
-
-Wheel files include an extended RECORD that enables digital
-signatures.  PEP 376's RECORD is altered to include a secure hash
-``digestname=urlsafe_b64encode_nopad(digest)`` (urlsafe base64
-encoding with no trailing = characters) as the second column instead
-of an md5sum.  All possible entries are hashed, including any
-generated files such as .pyc files, but not RECORD which cannot contain its
-own hash. For example::
-
-    file.py,sha256=AVTFPZpEKzuHr7OvQZmhaU3LvwKz06AJw8mT\_pNh2yI,3144
-    distribution-1.0.dist-info/RECORD,,
-
-The signature file(s) RECORD.jws and RECORD.p7s are not mentioned in
-RECORD at all since they can only be added after RECORD is generated.
-Every other file in the archive must have a correct hash in RECORD
-or the installation will fail.
-
-If JSON web signatures are used, one or more JSON Web Signature JSON
-Serialization (JWS-JS) signatures is stored in a file RECORD.jws adjacent
-to RECORD.  JWS is used to sign RECORD by including the SHA-256 hash of
-RECORD as the signature's JSON payload:
-
-.. code-block:: json
-
-    { "hash": "sha256=ADD-r2urObZHcxBW3Cr-vDCu5RJwT4CaRTHiFmbcIYY" }
-
-(The hash value is the same format used in RECORD.)
-
-If RECORD.p7s is used, it must contain a detached S/MIME format signature
-of RECORD.
-
-A wheel installer is not required to understand digital signatures but
-MUST verify the hashes in RECORD against the extracted file contents.
-When the installer checks file hashes against RECORD, a separate signature
-checker only needs to establish that RECORD matches the signature.

 FAQ

     in *wheel's* ``.data`` directory.
 
 
-Why does wheel include attached signatures?
--------------------------------------------
-
-    Attached signatures are more convenient than detached signatures
-    because they travel with the archive.  Since only the individual files
-    are signed, the archive can be recompressed without invalidating
-    the signature or individual files can be verified without having
-    to download the whole archive.
-
-
-Why does wheel allow JWS signatures?
-------------------------------------
-
-    The JOSE specifications of which JWS is a part are designed to be easy
-    to implement, a feature that is also one of wheel's primary design
-    goals.  JWS yields a useful, concise pure-Python implementation.
-
-
-Why does wheel also allow S/MIME signatures?
---------------------------------------------
-
-    S/MIME signatures are allowed for users who need or want to use
-    existing public key infrastructure with wheel.
-
-    Signed packages are only a basic building block in a secure package
-    update system.  Wheel only provides the building block.
