Different options of hash-function (*)
Starting from the childhood they said I'm a father's daughter. I look like him. I love coffee and photography as he did.
He went 19 years ago. It was his own decision. A suicide. Why? I still don't know. It happened in September 2001 - 4 days after the terrorist attack to the World Trade Center and the Pentagon. My father worked in the KGB in the Government Information Security Department. He was a mathematician, cryptograph. I don't know the details - he never told me about his job. We had a family legend that the father is a program developer. I understood about cryptography only when matched books from father's library and the fact he worked with laptop since the end of 1980-s.
I miss him. That was the deepest pain in my life. My memories about him are under thick sarcophagus. Thus I meet him from the scratch looking through his photos and some personal stuff. I have a strong feeling that I need to find a language to communicate with my father today. I use several "keys" to decrypt our communication channel: photographic archive, fragments of memory, visual re-construction of my father's portrait, video recordings and mathematics.
(*) In cryptography hash-function in mostly called "hash" - it is a mathematical algorithm which transforms arbitrary data array into the line of letters and numbers of the certain length.
Designation: h(M) - hash function for the M
