'0.1.0'

Class Method Summary

• .hash(plain_integer, spin = 0, length = 10) ⇒ String

  Hash the given plain_integer into its obfuscated String form.

• .reverse_hash(hashed_integer, spin = 0, length = 10) ⇒ String

  Reverse hashed_integer from its obfuscated form to its serial value.

Class Method Details

.hash(plain_integer, spin = 0, length = 10) ⇒ String

Note:

To obtain the corresponding hashed integer value call hash(plain_integer).to_i

Hash the given plain_integer into its obfuscated String form.

Parameters:

• plain_integer (Fixnum) —

  the numeric value to be hashed.

• spin (Fixnum) (defaults to: 0) —

  the seed value for the hashing algorithm.

• length (Fixnum) (defaults to: 10) —

  the number of digits in the returned hash.

Returns:

• (String) —

  a ‘0’ padded string of length digits containing the hashed numeric value.

# File 'lib/scatter_swap.rb', line 14

def self.hash(plain_integer, spin = 0, length = 10)
  Hasher.new(plain_integer, spin, length).hash
end

.reverse_hash(hashed_integer, spin = 0, length = 10) ⇒ String

Note:

To obtain the corresponding reverse-hashed integer value call reverse_hash(hashed_integer).to_i

Reverse hashed_integer from its obfuscated form to its serial value.

Parameters:

• hashed_integer (Fixnum) —

  the numeric value to be hashed.

• spin (Fixnum) (defaults to: 0) —

  the seed value for the hashing algorithm.

• length (Fixnum) (defaults to: 10) —

  the number of digits in the returned hash.

Returns:

• (String) —

  a ‘0’ padded string of length digits containing the reverse-hashed numeric value.
