 // @Summary Register Credential Information
-// @Description This API registers credential information using hybrid encryption. 1. First, compress and encrypt sensitive data using a client generated AES with a 256-bit key. 2. Then, encrypt the AES key using an RSA public key obtained from `GET /credential/publicKey`. 3. RSA encryption uses a 4096-bit key with OAEP padding and SHA-256 as the hash function. Ensure that all values are base64 encoded before sending them in the request. The public key token ID must be included in the request to allow the server to decrypt the data.
