This is a program that implements authentication and key management. It includes RSA algorithm(C++/Python), a hybrid algorithm that combines ECDSA and AES(C++) and a hybrid algorithm that combines DES and DSA(Python).

c++_openssl includes two algorithms(RSA and ECDSA_AES) to authenticate, encrypt and decrypt string information, and calculate runtime.

c++_openssl_json includes two algorithms(RSA and ECDSA_AES) to authenticate, encrypt and decrypt json information, and calculate runtime.

python_rsa_dsa_des includes two algorithms(RSA and DSA_DES) to authenticate, encrypt and decrypt json information, and calculate runtime.
