A remote team of three hobbyist cryptologists have solved one of the Zodiac Killer's cipher after a half century.

The 340 Cipher, named after its 340 characters, was trickier to figure out - until this week, almost 50 years later, when an unlikely team of cryptographers broke the code.

"The FBI is aware that a cipher attributed to the Zodiac Killer was recently solved by private citizens," Cameron Polan, spokeswoman for the FBI's San Francisco office told The Chronicle.

"The Zodiac Killer case remains an ongoing investigation for the FBI San Francisco division and our local law-enforcement partners."

The key, according to Blake was looking at other directions the cipher could be read, and processing those with the 650,000 possibilities through a supercomputer at the University of Melbourne, he added.
