Software Usage Instructions

Set the generation range: Choose “Randomly generate a specified quantity” or “Generate all combinations,” then enter the password length, number of entries to generate, maximum entries per file, and output format.
Select character sets and rules: Check uppercase letters, lowercase letters, numbers, special symbols, or custom characters. You can also exclude easily confused characters.
Configure position rules: Set each position to use the global setting, uppercase, lowercase, numbers, symbols, or a custom character set; fixed characters support shortcuts such as A, a, 0, and #.
Set prefixes, suffixes, and deduplication: You can enter a unified prefix and suffix, and upload or paste existing TXT/CSV data to exclude duplicate content.
Calculate an estimate: Click “Calculate Estimate” to view the number of combinations, planned number of entries to generate, file count, and size estimate.
Generate and download: After confirming the parameters, click “Start Generation.” The results area will display the first 20 entries. You can download a single TXT/CSV file, or package multiple results into a ZIP for download.

FAQ

A: Random generation is suitable for creating a password list with a specified quantity; full-combination generation enumerates each character set position by position, making it suitable for scenarios that require a rule-based dictionary.

A: Please select at least one character type, or enter content in the custom character set. If a specific position is set to special symbols or custom characters, make sure the corresponding set is not empty.

A: A represents the uppercase letter set, a represents the lowercase letter set, 0 represents the number set, and # represents the symbol set. To lock the letter A, enter =A.

A: The number of combinations may be insufficient, deduplication for this run may be enabled, existing data may be excluded, or each character type may be required to appear but the length is too short. You can relax the character set, increase the length, or disable some restrictions.

A: Line contents in TXT or CSV files and comma-separated contents will be read as existing data. If “Exclude existing data” is selected during generation, these items will be skipped, and the file will not be uploaded to the server.

A: Generated results will be split into multiple TXT or CSV files based on the item limit. The results area displays buttons for the first 20 files, and all results can be downloaded together via “Download ZIP”.
