PassSeeder 1.0
About
passseeder is a language to generate passwords beginning from a set of alphanumeric list words (seeds) and a string of instructions (generator). To build the generator string there is a pre-defined set of instructions and a constrained range of values for parameters. We will call core word to each word in seeds.
Next, it is shown the syntax to build the generator string by using BNF:
generator = L+num + (M) + core
core = J+symb + (T+num) + W+id + core
Where...
- L is to limit the length of the password to generate, defined by num.
- num is a natural number between 1 (included) to infinity.
- M is for mix in a loop fashion throughout the core words.
- core is a sequence that defines how to traverse each core word.
- J is the way to jump characters in a core word, defined by symb.
- T is the way to take a certain number of character in each jump, defined by num.
- W represents the inclusion of a core words, identify by id.
- id is the identifier of a core word, which is a natural number.
symb could be:
- 1...infinity: jumping of 1, 2, 3, ..., infinity.
- f: Jumps by following Fibonacci sequence.
- a: arithmetic progression.
- g: geometric progression.
Example
*********************************************
****INPUTS***********************************
*** seeds : hello,world,1234567890,password
*** generator: L16MJ2W1J2W2J2W3J2W4
*********************************************
*** L16 : Length of 16 characters.
*** M : Mixed (iterate) among core words in seeds.
*** J2 W1 : Pick one character each 2 ones of word 1 (hello).
*** J2 W2 : Pick one character each 2 ones of word 2 (world).
*** J2 W3 : Pick one character each 2 ones of word 3 (1234567890).
*** J2 W4 : Pick one character each 2 ones of word 4 (password).
