--- Comment #20 from Tom Xin <766781...@qq.com> --- (In reply to Dominik Stadler from comment #19) > This is hopefully now fixed via r1907444 > > The code seems to not have taken into account that ciphers work on data in > 16-byte-chunks and so sometimes a bit more data needs to be read. > > By trying to read a few bytes more, the test-case and a number of new tests > now work fine and existing tests continue to work. > > > > What made it hard to find is that the JDK code silently ignores a chunk of > data if it's size is not a multiple of 16-bytes and just keeps using the > encrypted data!?: > > From > /usr/lib/jvm/java-11-openjdk-amd64/lib/src.zip!/java.base/com/sun/crypto/ > provider/CipherCore.java:720 > > // do not count the trailing bytes which do not make up a unit > len = (len > 0 ? (len - (len % unitBytes)) : 0); That's great! -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
