His DNA was found in two hideouts used by Paris attackers and also on explosive material, prosecutors have said.
The New York Times had sought release of the material; prosecutors had argued that making the documents public could, among other things, "prejudice the government's ongoing investigation".
He was charged with 1,544 counts of possessing child pornography and 1,544 counts of promoting it by uploading the material, prosecutors said.
Among the material prosecutors are studying is an online chat log in which Private Bradley Manning is said to claim that while he was downloading government files he was directly communicating with Assange using an encrypted internet conferencing service, according to the Times.

Lev Ponomaryov, the head of For Human Rights, has refused to hand over required material to prosecutors.
If that challenge fails, Judge Sciarrino said he would review the messages and then turn over the relevant material to prosecutors.
At the same time, the government was slow to turn over material to prosecutors, and as Judge Orie noted, some documents "were never provided".
Despite a confession and material evidence, prosecutors were forced to think creatively to win the maximum sentence -- 10 years in prison -- using, among other laws, one from 1934 that banned all private militias.
On seeing the material, Crown prosecutors realised it corroborated Begg's defence case: he insists he was always perfectly candid with MI5, and says the agency assured him no attempt would be made to hinder him if he wanted to return to Syria.
