This means that using today's common asymmetric encryption methods of RSA/ECC to encrypt certain types of data on a public blockchain should not be considered secure. That encrypted data is available to everyone ... and it won't stay encrypted for all that long. This is especially a problem for identity-related information, which is often sensitive and has a long shelf life. -- Dave Longley CTO Digital Bazaar, Inc. http://digitalbazaar.com
