And if there's a > salt used I can't tell how that would be referenced. It's generated by the crypt function in glibc — man 3 crypt, and scroll down to the "Glibc notes" section. Although I didn't dig further, that says that the characters in the resulting string are drawn from the set [a-zA-Z0-9./]; I assume that it's the same number as would be found in a sha512sum hash, except mapped to that instead of represented as a long hexadecimal number. (If you do want to dig further, I suppose sha512-crypt.c is the place to look.) If you want to generate such a string yourself, using the crypt function seems like the easiest way (of course using the python crypt module or whatever). -- Matthew Miller <mattdm@xxxxxxxxxxxxxxxxx> Fedora Project Leader -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
