I noticed descriptions about source hash are inconsistent in CSP Lv.2 Last Call Working Draft. http://www.w3.org/TR/CSP11/ http://www.w3.org/TR/CSP2/ In 4.2.5, the draft says "Let actual be the base64 encoding of the binary digest of element’s content using the algorithm algorithm.”, however in 7.17.2, says "For example, the SHA-256 digest of alert('Hello, world.'); is YWIzOWNiNzJjNDRlYzc4MTgwMDhmZDlkOWI0NTAyMjgyY2MyMWJlMWUyNjc1ODJlYWJhNjU5MGU4NmZmNGU3OAo=.”. The section 4.2.5 describe correctly according to the actual implementation for Google Chrome. The correct base64 encoded SHA-256 binary digest of alert(‘Hello, world.’); is qznLcsROx4GACP2dm0UCKCzCG+HiZ1guq6ZZDob/Tng=. It’s ovbious that the former is correct, and the latter is wrong though, this mistake is sometimes misleading. (It mislead me actually…) /** * Yu Yagihashi * yagihash@sfc.wide.ad.jp */
