Fedora Project

  • Updated perl-Crypt-DSA to 1.16, the first production release. The package has had quite an overhaul upstream, with a few dependency changes, but it built fine on my Fedora 11 box. However, a Rawhide build failed:

  • A look at the code suggested that openssl might be producing different output on Rawhide compared with older OS releases, and that indeed proved to be the case. Crypt::DSA::KeyChain runs openssl dsaparam -text -noout 512, which produces output like this on Fedora 11 (openssl 0.9.8k): 

  • $ openssl dsaparam -text -noout 512

  • The change to labelling the parameters in upper case is what broke things, and was easily fixed with this simple patch:
