Implementation of asymmetric encryption and digital signature RSA Algorithms (public key encryption-> Private Key decryption, private key encryption-> Public Key decryption)

The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured. The RSA algorithm consists of the generation of public and private keys, asymmetric encryptio

Differences between Oracle primary key constraint, unique key constraint, and unique index [primary key constraint and unique key

Generally, we can see that the terms "Index" and "key" are used for exchange, but they are actually different. An index is a physical structure stored in a database. A key is purely a logical concept. The key represents the integrity constraints created to implement business rules. The confusion between indexes and keys is generally caused by the use of indexes i

IPSec base-key exchange and key protection Internet Key Exchange (IKE)

Internet Key Exchange (IKE)Before exchanging data between two IPSec computers, a convention must be established first, a convention called a "security association", in which both parties need to agree on how to protect the information, exchange information, and other common security settings, and more importantly, there must be a way for the two computers to securely exchange a set of keys.

Php quickly queries the code of its parent key and parent key value based on the key name in a multi-dimensional array.

There is a multi-dimensional array, which can be customized. If we want to find a subIndex value in this array, we can use methods such as for and foreach to traverse and find the reverse. If we give one or more keys at will, you must find the keys and values of the parent-level array of the key. How can this be achieved? There is a multi-dimensional array, which can be customized. If we want to find a value with the
