A typical "heartbleed" tool. What makes this different is:

• autopwn most (-a) that does all the steps needed to get private key
• post-handshake (encrypted) heartbeats instead of during handshake
• evades Snort IDS rules
• loops making repeated requests (-l <loopcount>)
• dumps binary data to file (-f <filename>)
• IPv4 or IPv6 (-v <IPver>)
• full 64k heartbleeds
