Incorrect MAC
profcav opened this issue · 0 comments
I have generated 10000 crypted messages in python, about 40 of them causing incorrect MAC error in ecies-parity verify
The problem seems to be in this (javascript) part
Tracing one of the "bad" messages, I see in browser.js derive function:
privateKeyA
Uint8Array(32) [142, 11, 200, 145, 112, 236, 88, 70, 72, 85, 45, 54, 60, 137, 39, 164, 64, 173, 143, 227, 189, 30, 126, 130, 132, 209, 164, 192, 178, 231, 245, 7]
publicKeyB
Uint8Array(65) [4, 9, 46, 45, 197, 50, 92, 238, 205, 224, 221, 138, 77, 86, 171, 14, 220, 179, 211, 45, 205, 57, 75, 119, 58, 219, 229, 188, 167, 23, 149, 56, 79, 7, 212, 39, 1, 248, 247, 14, 82, 168, 124, 69, 223, 93, 179, 232, 4, 175, 3, 12, 34, 75, 145, 14, 44, 106, 177, 11, 60, 170, 170, 154, 41]
and the Buffer returned by the function is 31 bytes long instead of 32 bytes
