| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sorry, I was not reading the code of GNUnet well. I overlooked how the eddsa_d_to_a function was written and its intention. I read it again. Indeed, the eddsa_d_to_a function tries to handle the case where gcry_mpi_print returns rawmpilen < 32, putting "left pad" by DIGEST. The problem is: DIGEST is not cleared (although comment says so). I think that the stack had zero-byte for some reason on your 32-bit machine. Here is the correction. Clear DIGEST, as comment says. diff --git a/src/util/crypto_ecc.c b/src/util/crypto_ecc.c index 8d9091b23..280603234 100644 --- a/src/util/crypto_ecc.c +++ b/src/util/crypto_ecc.c @@ -1273,24 +1273,15 @@ eddsa_d_to_a (gcry_mpi_t d) b = 256 / 8; /* number of bytes in `d` */ + memset (hvec, 0, sizeof hvec); /* Note that we clear DIGEST so we can use it as input to left pad the key with zeroes for hashing. */ - memset (hvec, 0, sizeof hvec); + memset (digest, 0, sizeof digest); rawmpilen = sizeof (rawmpi); GNUNET_assert (0 == gcry_mpi_print (GCRYMPI_FMT_USG, rawmpi, rawmpilen, &rawmpilen, d)); - if (rawmpilen < 32) - { - memmove (rawmpi + 32 - rawmpilen, - rawmpi, - rawmpilen); - memset (rawmpi, - 0, - 32 - rawmpilen); - rawmpilen = 32; - } hvec[0].data = digest; hvec[0].off = 0; hvec[0].len = b > rawmpilen ?
