I don't know a definite answer, but I wouldn't put money on it. Very long read but I'd suggest taking the time to do so. A bit butchered from the article but relevant to your question.
There is still one technology preventing untrammeled government access to private digital data: strong encryption. ... Most experts say that a so-called brute-force computer attack on the algorithm[AES]trying one combination after another to unlock the encryptionwould likely take longer than the age of the universe. For a 128-bit cipher, the number of trial-and-error attempts would be 340 undecillion (10 ^36 ). ...
Meanwhile, over in Building 5300, the NSA succeeded in building an even faster supercomputer. They made a big breakthrough, says another former senior intelligence official, who helped oversee the program. The NSAs machine was likely similar to the unclassified Jaguar, but it was much faster out of the gate, modified specifically for cryptanalysis and targeted against one or more specific algorithms, like the AES. In other words, they were moving from the research and development phase to actually attacking extremely difficult encryption systems. The code-breaking effort was up and running.
The breakthrough was enormous, says the former official, and soon afterward the agency pulled the shade down tight on the project, even within the intelligence community and Congress. Only the chairman and vice chairman and the two staff directors of each intelligence committee were told about it, he says. The reason? They were thinking that this computing breakthrough was going to give them the ability to crack current public encryption.
