API Documentation

Password Generation (functions.Create)

Generates a secure password with mixed character types.

func Create(length int) string

Parameters:

• length: Desired password length (minimum 8 characters)

Returns:

• Generated password string containing lowercase, uppercase, numbers, and symbols

Example:

password := functions.Create(12)
// Returns: "aB3#fG7@kL9$"

Password Validation (functions.Check)

Analyzes password strength and identifies security issues.

func Check(password string) (bool, PasswordStrength, []string)

Parameters:

• password: Password string to validate

Returns:

• bool: Whether password is valid (no critical issues)
• PasswordStrength: Strength level (Weak, Medium, Strong, VeryStrong)
• []string: List of identified issues

Validation Criteria:

• Minimum 8 characters length
• Contains lowercase letters
• Contains uppercase letters
• Contains numbers
• Contains symbols
• Avoids common patterns ("password", "123456")

Example:

isValid, strength, issues := functions.Check("MyPass123!")

func Update(oldPass string) string

Parameters:

• oldPass: Existing password to enhance

// Returns: "oldpassaB3#"

Password Strength Levels

Level	Score Range	Description
Weak	≤ 2	Missing multiple security criteria
Medium	3-4	Meets basic requirements
Strong	5-6	Good security with most criteria met
VeryStrong	≥ 7	Excellent security with all criteria exceeded

Security Features

• Character Diversity: Ensures mix of character types
• Length Validation: Enforces minimum security standards
• Pattern Detection: Identifies common weak patterns
• Strength Scoring: Quantitative security assessment
• Visual Feedback: Color-coded issue reporting
