Hiya, just checking here - the bug we found in JS was when the message field input to Blake2B was were 5 or more of the first bytes were nonzero. The test cases in the EIP use the string abc (so the first 3 bytes are nonzero, the rest are), which are probably taken from the RFC. If we input the string abcde then we had a consensus bug due to wrongly converting the input. If these test cases have any input string where the m (message) field of the Blake2B input is 5 nonzero bytes or more, then this should cover our case.

The test case which should be added to the EIP to cover our case was;

  {
    input: '0000000c48c9bdf267e6096a3ba7ca8485ae67bb2bf894fe72f36e3cf1361d5f3af54fa5d182e6ad7f520e511f6c3e2b8c68059b6bbd41fbabd9831f79217e1319cde05b61626364650000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000500000000000000000000000000000001',

Thank you, sorry I misunderstood. I'll add more test cases with different message lengths.
