> NIST advises [1] SHA1 has been scheduled for EOL in 2010. Recent research[2] has revealed new vulnerabilities in SHA1.  
> DSA requires a 160bit hash with SHA1 the most common choice. DSA has a 1024bit key length. This is considered too short[4] with 4096 bits being better but 8192 preferrable. Most digital signatures - including many of those which secure the WOT[3] and Apache releases- use SHA1 and SDA. 
> Debian are preparing to start transitioning away from DSA and SHA1[5]. Apache should think about how to do the same.
