brief introduction One of the cryptographic algorithms that we will introduce today is bcrypt, a cryptographic hash function designed by Niels Provos and David Mazi res, which was based on the Blowfish password and was introduced at USENIX in 1999. In addition to adding salt to protect against rainbow table attacks, one of the most import ...

subject describe Title Description If the sum of two positive integers is prime, the two positive integers are called "prime partners", such as 2 and 5, 6 and 13, which can be applied to communication encryption. Now the society of cryptography asks you to design a program to select several pairs from the existing N (N is an even nu ...
