The Setting of F Parameters

[yhf]

it is said parameter f is the dimensions of fingerprints.
How does the f parameter affect the hash value of the result？
I tried to compute the results of "abc" and "aaa", and found that the length was 64, and the other was 63.

@yhfwww the other is 63 because the leading bit is 0. Hope that helps you understand it.
