 Changes between 0.9.5 and 0.9.5a  [XX XXX 2000]



  *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length

     was larger than the MD block size.      

     [Steve Henson, pointed out by Yost William <YostW@tce.com>]



  *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument

     fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()

     using the passed key: if the passed key was a private key the result

crypto/hmac/hmac.c
