password-generator

密码生成器

生成具备密码学安全性的密码和易记的密码短语。自定义字符集、长度和规则。包含强度检查和批量生成。

快速开始

from scripts.password_gen import PasswordGenerator

# Generate password
gen = PasswordGenerator()
password = gen.generate(length=16)
print(password)  # "K#9mPx$vL2nQ@8wR"

# Generate passphrase
passphrase = gen.passphrase(words=4)
print(passphrase)  # "correct-horse-battery-staple"

功能

• 安全生成：使用密码学安全的随机数
• 自定义规则：字符集、必需类型、排除项
• 密码短语：基于单词的易记密码
• 强度检查：评估密码强度
• 批量生成：生成多个密码
• 易于读出：生成更易输入的密码

API 参考

基本生成

gen = PasswordGenerator()

# Default (16 chars, mixed)
password = gen.generate()

# Custom length
password = gen.generate(length=24)

字符选项

# Include/exclude character types
password = gen.generate(
    length=16,
    uppercase=True,
    lowercase=True,
    digits=True,
    symbols=True
)

# Exclude ambiguous characters (0, O, l, 1, etc.)
password = gen.generate(length=16, exclude_ambiguous=True)

# Custom character set
password = gen.generate(length=16, charset="abc123!@#")

# Exclude specific characters
password = gen.generate(length=16, exclude="{}[]")

要求

# Require at least N of each type
password = gen.generate(
    length=16,
    min_uppercase=2,
    min_lowercase=2,
    min_digits=2,
    min_symbols=2
)

密码短语

# Word-based passphrase
passphrase = gen.passphrase(words=4)
# "correct-horse-battery-staple"

# Custom separator
passphrase = gen.passphrase(words=4, separator="_")
# "correct_horse_battery_staple"

# With number
passphrase = gen.passphrase(words=3, include_number=True)
# "correct-horse-42-battery"

# Capitalize words
passphrase = gen.passphrase(words=4, capitalize=True)
# "Correct-Horse-Battery-Staple"

强度检查

strength = gen.check_strength("MyP@ssw0rd!")
# {
#     'score': 3,           # 0-4 scale
#     'label': 'Strong',    # Weak, Fair, Good, Strong, Very Strong
#     'entropy': 65.2,      # Bits of entropy
#     'feedback': ['Good length', 'Has symbols']
# }

批量生成

# Generate multiple passwords
passwords = gen.generate_bulk(count=10, length=16)

# To CSV
gen.generate_to_csv("passwords.csv", count=100, length=20)

CLI 用法

# Generate single password
python password_gen.py --length 16

# Generate passphrase
python password_gen.py --passphrase --words 4

# Custom options
python password_gen.py --length 20 --no-symbols --exclude-ambiguous

# Bulk generate
python password_gen.py --count 10 --length 16

# Check strength
python password_gen.py --check "MyPassword123!"

# Generate to file
python password_gen.py --count 100 --output passwords.txt

示例

强随机密码

gen = PasswordGenerator()
password = gen.generate(
    length=20,
    min_uppercase=2,
    min_lowercase=2,
    min_digits=2,
    min_symbols=2
)
print(f"Password: {password}")
print(f"Strength: {gen.check_strength(password)['label']}")

易记的密码短语

gen = PasswordGenerator()
passphrase = gen.passphrase(
    words=4,
    capitalize=True,
    include_number=True,
    separator="-"
)
print(passphrase)
# "Tiger-Mountain-42-Sunset-Lake"

PIN 生成

gen = PasswordGenerator()
pin = gen.generate(
    length=6,
    uppercase=False,
    lowercase=False,
    digits=True,
    symbols=False
)
print(f"PIN: {pin}")  # "847291"

团队批量生成

gen = PasswordGenerator()

# Generate passwords for new team members
team = ["alice", "bob", "charlie"]
for member in team:
    password = gen.generate(length=16)
    print(f"{member}: {password}")

强度评分

评分	标签	描述

安全说明

• 使用 secrets 模块生成密码学安全的随机数
• 从不记录或存储生成的密码
• 密码短语词表内置（不进行外部调用）
• 强度检查在本地进行（不调用外部 API）
