+      Create a password hash using some scheme specific format.
+      Eg PBKDF2 and PGP-S2K set iterations in i1
+      Scrypt uses N,r,p in i{1-3}
+      Bcrypt-PBKDF just has iterations
+      Argon2{i,d,id} would use iterations, memory, parallelism for i{1-3}, and Argon2 type is part of the family.

+      Values not needed should be set to 0.
