Subject: Make `openssl x509 -noout -modulus' functional also for DSA certificates (in
X-Git-Tag: OpenSSL_0_9_2b~116
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7be304acdb36feddccb2b1d324c67fd1cefdfe2a;p=oweals%2Fopenssl.git

Make `openssl x509 -noout -modulus' functional also for DSA certificates (in
addition to RSA certificates) to match the behaviour of `openssl dsa -noout
-modulus' as it's already the case for `openssl rsa -noout -modulus'.  For RSA
the -modulus is the real "modulus" while for DSA currently the public key is
printed (a decision which was already done by `openssl dsa -modulus' in the
past) which serves a similar purpose.  Additionally the NO_RSA no longer
completely removes the whole -modulus option; it now only avoids using the RSA
stuff. Same applies to NO_DSA now, too.

   *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
      BIO. See the source (crypto/evp/bio_ok.c) for more info.
