Nunchuk would install, but I can't verify the checksum with the APK.
The APK package sum is:
io.nunchuk.android
79:B1:CD:71:DE:5F:19:C6:23:6D:4E:3E:F1:34:B5:B6:91:CF:05:1A:13:89:44:BD:A0:1B:64:0B:3E:9B:1D:42
27:1D:CF:93:E8:74:1E:83:E3:67:EC:1F:7B:D8:E9:D6:A2:E8:EB:87:72:3C:89:67:7E:25:8F:36:44:F8:07:BB
The cert provided is:
79b1cd71de5f19c6236d4e3ef134b5b691cf051a138944bda01b640b3e9b1d42
Seemingly there are 32 extra bytes of data in that field for some reason.
