+     We can't use an off-the-shelf Hashcash because Apple's implementation is not quite the same as the spec/convention.
+     1. The spec calls for a nonce called "Rand" to be inserted between the Ext and Counter. They don't do that at all.
+     2. The Counter conventionally encoded as base-64 but Apple just uses the decimal number's string representation.
+      
+     Iterate from Counter=0 to Counter=N finding an N that makes the SHA1(X-APPLE-HC) lead with Bits leading zero bits
+     We get the "Resource" from the X-Apple-HC-Challenge header and Bits from X-Apple-HC-Bits

+\
+      "Work" shall mean the work of authorship, whether in Source or\
+      Object form, made available under the License, as indicated by a\
+      copyright notice that is included in or attached to the work\
+      (an example is provided in the Appendix below).\
+\
+      "Derivative Works" shall mean any work, whether in Source or Object\
+      form, that is based on (or derived from) the Work and for which the\
+      editorial revisions, annotations, elaborations, or other modifications\
+      represent, as a whole, an original work of authorship. For the purposes\
+      of this License, Derivative Works shall not include works that remain\
+      separable from, or merely link (or bind by name) to the interfaces of,\
+      the Work and Derivative Works thereof.\
+\
+      "Contribution" shall mean any work of authorship, including\

+      by such Contributor that are necessarily infringed by their\
+      Contribution(s) alone or by combination of their Contribution(s)\
+      with the Work to which such Contribution(s) was submitted. If You\
+      institute patent litigation against any entity (including a\
+      cross-claim or counterclaim in a lawsuit) alleging that the Work\
+      or a Contribution incorporated within the Work constitutes direct\
+      or contributory patent infringement, then any patent licenses\
+      granted to You under this License for that Work shall terminate\
+      as of the date such litigation is filed.\
+\
+   4. Redistribution. You may reproduce and distribute copies of the\

+          attribution notices from the Source form of the Work,\
+          excluding those notices that do not pertain to any part of\
+          the Derivative Works; and\
+\
+      (d) If the Work includes a "NOTICE" text file as part of its\
+          distribution, then any Derivative Works that You distribute must\
+          include a readable copy of the attribution notices contained\
+          within such NOTICE file, excluding those notices that do not\
+          pertain to any part of the Derivative Works, in at least one\
+          of the following places: within a NOTICE text file distributed\
+          as part of the Derivative Works; within the Source form or\
+          documentation, if provided along with the Derivative Works; or,\
+          within a display generated by the Derivative Works, if and\
+          wherever such third-party notices normally appear. The contents\
+          of the NOTICE file are for informational purposes only and\
+          do not modify the License. You may add Your own attribution\
+          notices within Derivative Works that You distribute, alongside\
+          or as an addendum to the NOTICE text from the Work, provided\
+          that such additional attribution notices cannot be construed\
+          as modifying the License.\
+\
+      You may add Your own copyright statement to Your modifications and\
+      may provide additional or different license terms and conditions\
+      for use, reproduction, or distribution of Your modifications, or\
+      for any such Derivative Works as a whole, provided Your use,\
+      reproduction, and distribution of the Work otherwise complies with\
+      the conditions stated in this License.\
+\
+   5. Submission of Contributions. Unless You explicitly state otherwise,\
+      any Contribution intentionally submitted for inclusion in the Work\
+      by You to the Licensor shall be under the terms and conditions of\
+      this License, without any additional terms or conditions.\
+      Notwithstanding the above, nothing herein shall supersede or modify\
+      the terms of any separate license agreement you may have executed\
+      with Licensor regarding such Contributions.\
+\
+   6. Trademarks. This License does not grant permission to use the trade\
+      names, trademarks, service marks, or product names of the Licensor,\
+      except as required for reasonable and customary use in describing the\
+      origin of the Work and reproducing the content of the NOTICE file.\
+\
+   7. Disclaimer of Warranty. Unless required by applicable law or\
+      agreed to in writing, Licensor provides the Work (and each\
+      Contributor provides its Contributions) on an "AS IS" BASIS,\
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\
+      implied, including, without limitation, any warranties or conditions\
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\
+      PARTICULAR PURPOSE. You are solely responsible for determining the\
+      appropriateness of using or redistributing the Work and assume any\
+      risks associated with Your exercise of permissions under this License.\
+\
+   8. Limitation of Liability. In no event and under no legal theory,\
+      whether in tort (including negligence), contract, or otherwise,\
+      unless required by applicable law (such as deliberate and grossly\
+      negligent acts) or agreed to in writing, shall any Contributor be\
+      liable to You for damages, including any direct, indirect, special,\
+      incidental, or consequential damages of any character arising as a\
+      result of this License or out of the use or inability to use the\
+      Work (including but not limited to damages for loss of goodwill,\
+      work stoppage, computer failure or malfunction, or any and all\
+      other commercial damages or losses), even if such Contributor\
+      has been advised of the possibility of such damages.\
+\
+   9. Accepting Warranty or Additional Liability. While redistributing\
+      the Work or Derivative Works thereof, You may choose to offer,\
+      and charge a fee for, acceptance of support, warranty, indemnity,\
+      or other liability obligations and/or rights consistent with this\
+      License. However, in accepting such obligations, You may act only\
+      on Your own behalf and on Your sole responsibility, not on behalf\
+      of any other Contributor, and only if You agree to indemnify,\
+      defend, and hold each Contributor harmless for any liability\
+      incurred by, or claims asserted against, such Contributor by reason\
+      of your accepting any such warranty or additional liability.\

+\
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION\
+\
+   1. Definitions.\
+\
+      "License" shall mean the terms and conditions for use, reproduction,\
+      and distribution as defined by Sections 1 through 9 of this document.\

+      direction or management of such entity, whether by contract or\
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the\

+\
+      "Source" form shall mean the preferred form for making modifications,\
+      including but not limited to software source code, documentation\
+      source, and configuration files.\
+\
+      "Object" form shall mean any form resulting from mechanical\
+      transformation or translation of a Source form, including but\
+      not limited to compiled object code, generated documentation,\
+      and conversions to other media types.\
+\
+      "Work" shall mean the work of authorship, whether in Source or\
+      Object form, made available under the License, as indicated by a\
+      copyright notice that is included in or attached to the work\
+      (an example is provided in the Appendix below).\
+\
+      "Derivative Works" shall mean any work, whether in Source or Object\
+      form, that is based on (or derived from) the Work and for which the\
+      editorial revisions, annotations, elaborations, or other modifications\
+      represent, as a whole, an original work of authorship. For the purposes\
+      of this License, Derivative Works shall not include works that remain\
+      separable from, or merely link (or bind by name) to the interfaces of,\
+      the Work and Derivative Works thereof.\
+\
+      "Contribution" shall mean any work of authorship, including\
+      the original version of the Work and any modifications or additions\
+      to that Work or Derivative Works thereof, that is intentionally\
+      submitted to Licensor for inclusion in the Work by the copyright owner\
+      or by an individual or Legal Entity authorized to submit on behalf of\
+      the copyright owner. For the purposes of this definition, "submitted"\
+      means any form of electronic, verbal, or written communication sent\
+      to the Licensor or its representatives, including but not limited to\
+      communication on electronic mailing lists, source code control systems,\
+      and issue tracking systems that are managed by, or on behalf of, the\
+      Licensor for the purpose of discussing and improving the Work, but\
+      excluding communication that is conspicuously marked or otherwise\
+      designated in writing by the copyright owner as "Not a Contribution."\
+\
+      "Contributor" shall mean Licensor and any individual or Legal Entity\
+      on behalf of whom a Contribution has been received by Licensor and\
+      subsequently incorporated within the Work.\
+\
+   2. Grant of Copyright License. Subject to the terms and conditions of\
+      this License, each Contributor hereby grants to You a perpetual,\
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable\
+      copyright license to reproduce, prepare Derivative Works of,\
+      publicly display, publicly perform, sublicense, and distribute the\
+      Work and such Derivative Works in Source or Object form.\
+\
+   3. Grant of Patent License. Subject to the terms and conditions of\
+      this License, each Contributor hereby grants to You a perpetual,\
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable\
+      (except as stated in this section) patent license to make, have made,\
+      use, offer to sell, sell, import, and otherwise transfer the Work,\
+      where such license applies only to those patent claims licensable\
+      by such Contributor that are necessarily infringed by their\
+      Contribution(s) alone or by combination of their Contribution(s)\
+      with the Work to which such Contribution(s) was submitted. If You\
+      institute patent litigation against any entity (including a\
+      cross-claim or counterclaim in a lawsuit) alleging that the Work\
+      or a Contribution incorporated within the Work constitutes direct\
+      or contributory patent infringement, then any patent licenses\
+      granted to You under this License for that Work shall terminate\
+      as of the date such litigation is filed.\
+\
+   4. Redistribution. You may reproduce and distribute copies of the\
+      Work or Derivative Works thereof in any medium, with or without\
+      modifications, and in Source or Object form, provided that You\
+      meet the following conditions:\
+\
+      (a) You must give any other recipients of the Work or\
+          Derivative Works a copy of this License; and\
+\
+      (b) You must cause any modified files to carry prominent notices\
+          stating that You changed the files; and\
+\
+      (c) You must retain, in the Source form of any Derivative Works\
+          that You distribute, all copyright, patent, trademark, and\
+          attribution notices from the Source form of the Work,\
+          excluding those notices that do not pertain to any part of\
+          the Derivative Works; and\
+\
+      (d) If the Work includes a "NOTICE" text file as part of its\
+          distribution, then any Derivative Works that You distribute must\
+          include a readable copy of the attribution notices contained\
+          within such NOTICE file, excluding those notices that do not\
+          pertain to any part of the Derivative Works, in at least one\
+          of the following places: within a NOTICE text file distributed\
+          as part of the Derivative Works; within the Source form or\
+          documentation, if provided along with the Derivative Works; or,\
+          within a display generated by the Derivative Works, if and\
+          wherever such third-party notices normally appear. The contents\
+          of the NOTICE file are for informational purposes only and\
+          do not modify the License. You may add Your own attribution\
+          notices within Derivative Works that You distribute, alongside\
+          or as an addendum to the NOTICE text from the Work, provided\
+          that such additional attribution notices cannot be construed\
+          as modifying the License.\
+\
+      You may add Your own copyright statement to Your modifications and\
+      may provide additional or different license terms and conditions\
+      for use, reproduction, or distribution of Your modifications, or\
+      for any such Derivative Works as a whole, provided Your use,\
+      reproduction, and distribution of the Work otherwise complies with\
+      the conditions stated in this License.\
+\
+   5. Submission of Contributions. Unless You explicitly state otherwise,\
+      any Contribution intentionally submitted for inclusion in the Work\
+      by You to the Licensor shall be under the terms and conditions of\
+      this License, without any additional terms or conditions.\
+      Notwithstanding the above, nothing herein shall supersede or modify\
+      the terms of any separate license agreement you may have executed\
+      with Licensor regarding such Contributions.\
+\
+   6. Trademarks. This License does not grant permission to use the trade\
+      names, trademarks, service marks, or product names of the Licensor,\
+      except as required for reasonable and customary use in describing the\
+      origin of the Work and reproducing the content of the NOTICE file.\
+\
+   7. Disclaimer of Warranty. Unless required by applicable law or\
+      agreed to in writing, Licensor provides the Work (and each\
+      Contributor provides its Contributions) on an "AS IS" BASIS,\
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\
+      implied, including, without limitation, any warranties or conditions\
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\
+      PARTICULAR PURPOSE. You are solely responsible for determining the\
+      appropriateness of using or redistributing the Work and assume any\
+      risks associated with Your exercise of permissions under this License.\
+\
+   8. Limitation of Liability. In no event and under no legal theory,\
+      whether in tort (including negligence), contract, or otherwise,\
+      unless required by applicable law (such as deliberate and grossly\
+      negligent acts) or agreed to in writing, shall any Contributor be\
+      liable to You for damages, including any direct, indirect, special,\
+      incidental, or consequential damages of any character arising as a\
+      result of this License or out of the use or inability to use the\
+      Work (including but not limited to damages for loss of goodwill,\
+      work stoppage, computer failure or malfunction, or any and all\
+      other commercial damages or losses), even if such Contributor\
+      has been advised of the possibility of such damages.\
+\
+   9. Accepting Warranty or Additional Liability. While redistributing\
+      the Work or Derivative Works thereof, You may choose to offer,\
+      and charge a fee for, acceptance of support, warranty, indemnity,\
+      or other liability obligations and/or rights consistent with this\
+      License. However, in accepting such obligations, You may act only\
+      on Your own behalf and on Your sole responsibility, not on behalf\
+      of any other Contributor, and only if You agree to indemnify,\
+      defend, and hold each Contributor harmless for any liability\
+      incurred by, or claims asserted against, such Contributor by reason\
+      of your accepting any such warranty or additional liability.\
+\
+   END OF TERMS AND CONDITIONS\

+   APPENDIX: How to apply the Apache License to your work.\
+\
+      To apply the Apache License to your work, attach the following\
+      boilerplate notice, with the fields enclosed by brackets "[]"\
