How much to unlock HC chip?

The encryption algorithm of Huatai MCU refers to a type of encryption algorithm developed by Huada Microelectronics to protect data security. This encryption algorithm is based on the hardware characteristics and software implementation of Huada MCU chips, and has high security and reliability
The encryption algorithm of Huada MCU adopts a combination of symmetric encryption and asymmetric encryption. Symmetric encryption refers to using the same key to encrypt and unlock data, while asymmetric encryption uses both public and private keys for encryption and unlocking. This combination method can ensure efficient data encryption and unlocking speed, as well as the security of the key
In the encryption algorithm of Huada MCU, the symmetric encryption part adopts AES (Advanced Encryption Standard) algorithm. AES algorithm is a widely used symmetric encryption algorithm with high security and performance. It uses a fixed length key to encrypt data, which can be 128 bits, 192 bits, or 256 bits in length. The AES algorithm encrypts data through multiple rounds of substitution, permutation, and obfuscation operations, ensuring the confidentiality of the data.
