Implement input validation for generateProof function

[adithyaakrishna]

The generateProof function in zk.ts could benefit from additional input validation to prevent potential errors and improve user experience.

Tasks:

1. Add type checking for the opts parameter using TypeScript interfaces.
2. Implement checks for required properties in the opts object.
3. Validate the algorithm property against the list of supported algorithms.
4. Add size checks for key, iv, and ciphertext based on the selected algorithm.
5. Implement appropriate error handling and throw descriptive error messages for invalid inputs.

Adding input validation will help prevent runtime errors and provide clearer feedback to users when incorrect parameters are provided.
