kaya-rekey: Binary key regeneration for kaya web applications
NAMEkaya-rekey - Binary key regeneration for kaya web applications
SYNOPSISkaya-rekey FILE1 [FILE2 [...]]
DESCRIPTIONkaya-rekey gives all Kaya binaries specified on the command line a new application secret key
The application secret key makes webapps and CGI programs secure, by encrypting the state transfers. If you receive a webapp or CGI binary from someone else, or you believe someone untrusted has had read access to your binary, you can use the kaya-rekey application to generate a new application secret key without needing a recompile.
Binary distributors of Kaya applications are strongly recommended to use 'kaya-rekey' as part of the installation process.
Prior to Kaya 0.3.0 this utility was called rekey
The latest release of Kaya can be obtained from <http://kayalang.org/download>
kaya-rekey will use /dev/random to generate the new key if possible. If /dev/random is unavailable (Windows without MinGW, for example), the new key will be generated pseudo-randomly. This may allow an attacker to easily guess the new key. In environments where security is a concern, therefore, we strongly recommend recompiling with kayac(1) rather than using kaya-rekey if /dev/random is unavailable.
kaya-rekey will give a warning when rekeying if /dev/random is unavailable.
Please report bugs in kaya-rekey to <kaya [at] kayalang.org>
kaya-rekey cannot rekey Kaya binaries generated with a compiler older than the switch to AES256 encryption (i.e. older than 0.2.0 final version)
In rare cases, kaya-rekey may not be able to successfully rekey a file and will print an error instead. You must recompile in this case to get a new application key.
