The following options are available: -E In this operation mode, &name; enumerates through all possible values for a password, given the list of characters allowed and the length specified. -c string Sets the string of characters allowed within passwords, when generating them randomly. -e Apply a specific hashing algorithm to the password generated. The list of passwords currently supported is: base64 (always supported) blowfish (Blowfish) des (single DES) md5 (MD5, always supported) sha1 (SHA-1) sha256 (SHA-256) shmd5 (shadow MD5) none (always supported) For the algorithms not explicitly mentioned as always supported, their availability depends on the implementation of the crypt 3 library on the system where &name; was compiled. -i Force a number of iterations to be performed when hashing passwords, for algorithms effectively supporting it. It otherwise defaults to a random value, in a range considered reasonable for the hashing algorithm selected. -i Force a number of iterations to be performed when hashing passwords, for algorithms effectively supporting it. It otherwise defaults to a random value, in a range considered reasonable for the hashing algorithm selected. -l Force the passwords generated to be of a fixed length. -M Maximum length for the passwords generated. -m Minimum length for the passwords generated. -n Total number of passwords to generate. When not set, it defaults to only one, except in enumeration mode where it processes the complete range of possibilities until exhaustion. -p Force a given value for the password generated. This is useful when generating hashes for pre-determined passwords. -S Do not seed the PRNG (pseudo-random number generator) ourselves. With this option set, the entropy pool is often not initialized, and the passwords generated predictable as a result. Use this option carefully, when you know that either the system does provide better entropy than &name;, or that it hurts performance in a situation where entropy is not required. -s Force a given value when salting the resulting password hash. This is only useful when selecting a hashing algorithm that effectively uses salt. Issues can be listed and reported at . login 1 , passwd 1
