Both links may be really helpful to gauge the hashes used for an skey system, theoretically. So thank you for providing them. But sadly, if I didn't miss anything, they do not describe the real life circumstances needed for some successful attack on the skey hashes. For example how much time is n

OpenBSD FAQ - Using S/Key - hash algorithm selection

2020-01-11 Thread Anders Andersson
While perusing the OpenBSD FAQ I came across the S/Key login system and noticed that there are three possible hashing algorithms to choose from: MD5, SHA1, and RIPEMD-160. Instinctively I wouldn't want to use any of these. RIPEMD-160 seems like the only one that hasn't been broken, but that's prob
