Crypto Algorithm Question - Hash Function with special properties
i am currently working on a project for developing a secure authentication platform and am in sorta need for a special type of function.
i need something that could satisfy the following mathematical properties:
hash(file1+x_1 )⊚hash(file2+x_1 )⊚hash(file3+x_1 )⊚hash(file4+x_1 )⊚hash(file5+x_1 )=password_1
hash(file1+x_2 )⊚hash(file2+x_2 )⊚hash(file3+x_2 )⊚hash(file4+x_2 )⊚hash(file5+x_2 )=hash(password_1⨀Y)=password_2,where Y= F(x_2)
- Y=F(x),ideally Y=x_2,but can be anything that works the maths
- ⊚is the joining function operator,this can be anything like addition,multiplication,etc
- ⨀ this can also be any operator.
i am hopeing that there might be some unconventional hash function that can enable this property.
please contat me if you need further explanation.
