Imports fine for me, using gpg --import and then pasting just the part
   from the begin line to the end line (including the begin and end
   lines). I'm guessing you're either trying to import the entire message
   or you're leaving out the begin and end lines.

     Or a super sneaky secret message hidden in plain sight?
     gpg --import yields:
     gpg: invalid radix64 character 3A skipped
     gpg: invalid radix64 character 2E skipped
     gpg: invalid radix64 character 2E skipped
     gpg: invalid radix64 character 3A skipped
     gpg: invalid radix64 character 3A skipped
     gpg: invalid radix64 character 2E skipped
     gpg: invalid radix64 character 2E skipped
     gpg: CRC error; 02A730 - 33E76E

     gpg: read_block: read error: Invalid packet
