Number of unique leaked password dumps identified as using a specific hashing algorithm, collected by KoreLogic over a six month period in 2014 (n=1,365):
For above the p = plaintext password, s = salt. This identifies how the chosen algorithm(s) are specifically used to hash the password and salt.
