What is a token?

A token is like a special key that represents something valuable but doesn't directly show what that valuable thing is. It's used to protect important information, like a secret code, without revealing the actual code itself.

Here are some options to define a token:

1. Text-Based Tokens:

   • Random Text: Generate random alphanumeric characters as tokens, ensuring uniqueness and unpredictability.

2. Alphanumeric Tokens:

   • Random Alphanumeric: Combine random letters and numbers to create tokens that are both secure and user-friendly.

3. Format-Preserved Tokens:

   • Preserve Certain Characters: Maintain specific characters, such as separators or hyphens, while tokenizing the rest of the data. This helps users recognize the format of the original data.

4. Custom Tokens:

   • User-Defined Patterns: Allow users to define their own token patterns or formats based on their needs and preferences.

5. Length of Tokens:

   • Fixed-Length Tokens: Specify a fixed length for tokens, ensuring consistency and compatibility with data structures.

   • Variable-Length Tokens: Allow tokens to vary in length based on the length of the original data.
