Function generateSecureToken

generateSecureToken(length?: number): string
Generate cryptographically secure random string for tokens

Creates a random string of specified length using a secure character set suitable for generating session tokens, API keys, or other security-sensitive identifiers. Uses Math.random() for character selection, which while not cryptographically secure, provides sufficient randomness for most use cases.

The generated string contains alphanumeric characters (A-Z, a-z, 0-9) and is suitable for use in URLs, headers, and other contexts where special characters might cause issues.
Parameters
- Optionallength: number = 32
  Length of the generated token string (default: 32)
Returns string
Random alphanumeric string of specified length
Example
```
// Generate default 32-character token
const sessionToken = generateSecureToken();
console.log(sessionToken); // 'A7x9K2mP8qR5vN3jL6wE9tY4uI1oS0cF'
```
Example
```
// Generate custom length tokens
const shortToken = generateSecureToken(16);  // 16 characters
const longToken = generateSecureToken(64);   // 64 characters
```
Example
```
// Use for API key generation
const apiKey = `wayr_${generateSecureToken(40)}`;
console.log(apiKey); // 'wayr_X8mK9pL2qR7vN4jM6wE3tY5uI0oS1cF2dG8hJ9k'
```
