# status needs testing. really could use the opinion on the crypto from someone with more experience in this area. haven't done performance tests. # intro this is cryptfile, an encrypted block file served over styx. for more information, see the manual page, cryptfile(4). # download see http://www.ueber.net/code/r/cryptfile for instructions. # install change the "mkconfig" if you don't have $ROOT set. now "mk" to compile and "mk install" to install the files. when building from within inferno, insert SYSHOST=Inferno and ROOT= in the mk invocations to override the values in the mkconfig. # licence & author this code is in the public domain, written by mechiel lukkien, reachable at mechiel@ueber.net. # todo: - after a "forget" the user enters a password. if it is wrong, the styx read/write on the file fails. this might upset file servers such as kfs much. perhaps it is better not to respond to the styx request until the user enters a correct password. - add option to change the password (but keep the key of course). involves making a new salt, deriving a new key, making a new iv and making a new crypted data (with new random cookie, the same key and the calculated sha1).
