#
#  V07_NON_BACKWARD_COMPATIBLE_CHANGE_001:
#
#     What: Computes the node id by performing a sha256 hash of the certificate's PGP signature, instead of simply picking up the last 20 bytes of it.
#
#     Why: There is no real risk in forging a certificate with the same ID as the authentication is performed over the PGP signature of the certificate
#           which hashes the full SSL certificate (i.e. the full serialized CERT_INFO structure). However the possibility to
#           create two certificates with the same IDs is a problem, as it can be used to cause disturbance in the software.
#
#     Backward compat: connexions impossible with non patched peers older than Nov 2017, probably because the SSL id that is computed is not the same on both side,
#                    and in particular unpatched peers see a cerficate with ID different (because computed with the old method) than the ID that was
#                    submitted when making friends.
#
#     Note: the advantage of basing the ID on the signature rather than the public key is not very clear, given that the signature is based on a hash
#           of the public key (and the rest of the certificate info).
#
#  V07_NON_BACKWARD_COMPATIBLE_CHANGE_002:
#
#     What: Use RSA+SHA256 instead of RSA+SHA1 for PGP certificate signatures
#
#     Why:  Sha1 is likely to be prone to primary collisions anytime soon, so it is urgent to turn to a more secure solution.
#
#     Backward compat: unpatched peers after Nov 2017 are able to verify signatures since openpgp-sdk already handle it.
#
#  V07_NON_BACKWARD_COMPATIBLE_CHANGE_003:
#
#      What: Do not hash PGP certificate twice when signing
#
#  	 Why: hasing twice is not per se a security issue, but it makes it harder to change the settings for hashing.
#
#  	 Backward compat: patched peers cannot connect to non patched peers older than Nov 2017.
