Equation [2] expresses the relationship between S, A, and M where: S = password space A = number of alphabet symbols M = password length S = AM [2] To illustrate: If passwords consisting of 4 digits using an alphabet of 10 digits (e.g., 0-9) are to be generated: S = 104 That is, 10,000 unique 4-digit passwords could be generated. Likewise, to generate random 6-character passwords from an alphabet of 26 characters (e.g., AZ): S = 266 That is 3.089 * 108 unique 6-character passwords could be generated. "User-friendly" passwords (sometimes referred to as passphrases) could be generated by using, for example, 3 symbols from an alphabet (dictionary) of 2000 symbols, where each symbol was a pronounceable word of 4, 5, or 6 characters. Using equation [2] and setting: A = 2000 symbols (words) M = 3 Then S = 20003 That is, 8 * 109 unique passwords could be generated where each password was made up of 3 words taken from a dictionary of 2000 words. >- они уже интересовались, кажется, в pam-list'е как же им его реализовать > на pam_passwdqc... Бэкдору для ФСБ оставь, грамоту дадут. :)
