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:
Random Text: Generate random alphanumeric characters as tokens, ensuring uniqueness and unpredictability.
Random Alphanumeric: Combine random letters and numbers to create tokens that are both secure and user-friendly.
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.
User-Defined Patterns: Allow users to define their own token patterns or formats based on their needs and preferences.
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.
