buffer_put_bignum2_from_string question
Hello,
I have question about buffer_put_bignum2_from_string
function used in kexc25519.c in (OpenSSH >= 6.5)
Is it 1:1 replacement for formating bignums from OpenSSL?
If yes, then buffer_put_bignum2_from_string
has different results for numbers starting with zeros.
How to reproduce:
shared_key[CURVE25519_SIZE] = "\0\0\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1";
buffer_put_bignum2_from_string(out, shared_key, CURVE25519_SIZE);
and than same number format into bignum and than into wire format.
Best regards,
Jan
