Abstract Many applications still utilize older cryptographic technologies, even though security professionals warned that these are obsolete and unsafe to use. Some implementations can easily be upgraded to current encryption and contain a graceful fall-back for situations where it’s required, such as when a remote party only supports legacy technologies (e.g., TLS downgraded connections). Other… Read More

Smoke – A unified means of generating, transmitting, encapsulating, and validating multiple hash digests simultaneously to replace existing stand-alone hash digest software. The software generates digests in parallel and is notably faster than using individual algorithms serially on large files. Smoke operates much the same way as existing hash digest tools, like md5sum, and Smoke… Read More


Background & Summary Existing websites and applications implementing an older password hashing algorithm like MD5 or SHA1 must be upgraded to a more secure algorithm. Both of these older algorithms are obsolete & breakable and if an attacker obtains those hashes from a lost backup tape or website vulnerability, the attacker could make quick work… Read More
