Too few rounds in case of calculating the hash

Back to Catalog
Goal Find user-defined routines where gen_salt function is used with the number of rounds that is smaller than 12. The number should be adjusted based on the hardware where the system resides. Password hashing should take at least 250 ms.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability Medium (Medium number of false-positive results)
License MIT License
Fixing Suggestion "You should use the maximum number of rounds which is tolerable, performance-wise, in your application. The number of rounds is a slowdown factor, which you use on the basis that under normal usage conditions, such a slowdown has negligible impact for you (the user will not see it, the extra CPU cost does not imply buying a bigger server, and so on). " (Pornin, 2011)
