[ I am a US citizen in the US, so I'm resending this with a Cc to
[EMAIL PROTECTED] Sorry for not reading the README. I also
sent this to openssl-users after reading on the web pages that
openssl-dev submissions were restricted to subscribers, thinking
that my openssl-dev note would be dropped by majordomo. Sorry
for making such a mess over a trivial patch! ]
This minor patch fixes a warning we get from our code when we pass
a constant string to EVP_BytesToKey as the salt string. We have
our warnings treated in errors in our code base, so it'd be nice
to get this minor correction folded back into the master OpenSSL
sources.
EVP_BytesToKey only passes SALT off to EVP_DigestUpdate(), which
declares that parameter as (const void *), so changing the decl
from (unsigned char *) to (const unsigned char *) in EVP_BytesToKey
is harmless (constness is preserved, and we should let the compiler
know about it).
This patch was generated against openssl-0.9.6a.
Thanks!
