* KeyPair::check_key's behavior of throwing an exception upon failure waslloyd2010-03-211-15/+1
| | | | | | | | | | | | | | not useful; in all cases, we immediately caught it and then returned false. Modify as follows: - Create the pubkey objects inside the checking code, so calling code doesn't need to do it. - Return true/false for pass/fail Also add consistency checking for ECDSA keys
* DSA and NR require certain parameters (which depend on the randomlylloyd2010-03-091-9/+12

* Deconstify PK_Ops. It's quite reasonable that some op will want tolloyd2010-03-091-2/+2

Use the operations public op to hide the secret, for instance the seed for a DH blinding variable is 2^x mod p. Make use of being able to mutate internal structures in the RW signer, since that does have access to a PRNG, so use it to initialize the blinder on first call to sign().

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-301-31/+33
| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).
* Split Diffie-Hellman off almost completely, such that nearly none oflloyd2008-10-011-0/+1
