It was only a matter of time before it happened, but a group of researchers have cracked the 768-bit RSA encryption. An international team of cryptographers, scientists and mathematicians spent two-and-a-half years with hundreds of computers, and finally broke the encryption. Just the first step of the computation took the equivalent of 1,500 years on one core of a x86 processor resulting in 5 terabytes of data.
The explanation of how the encryption was broken would give the most technical of us a headache, but the implications should be considered. You would be hard pressed to find 768-bit encryption in use today, but 1024 bit encryption is widely used. So how long before 1024-bit encryption is broken? That timeline us up for debate . While the effort will be 1,000 times more difficult than 768-bit, some believe it can be broken within ten years.
