passseder - A new way to generate passwords

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).

Another example:

• Seeds    : hello,world,1234567890,password
• Generator: L32MJ2W1JgW2J1W3JaW4
