Asymmetric encryption has been rated as the encryption standard, mainly includes (public key encryption private key decryption, or private key encryption public key decryption) This article mainly explains how to generate the public and private keys and string encryption and string decryption in JavaIf you need code co
algorithm that can be used for both encryption and digital signature, and is easy to understand and operate. RSA is the most widely studied public key algorithm. It has been nearly two decades since it was proposed. It has been tested by various attacks and is gradually accepted by people, it is generally regarded as one of the best public key solutions. The enc
and q-1 (least common multiple, LCM), and with LCM (x, y) to represent "x and y least common multiple", the L can be expressed as:
L = LCM (p-1, q-1)
(3) Ask EThe following relationship exists between E and L:
1
GCD (E, l) = 1 E and L greatest common divisor 1 (E and L coprime)
To find the number that satisfies gcd (E, L) = 1, or to use a pseudo-random number generator. The pseudo-random number

-f4 use F4 (0x10001) for the E value (using F4 as the e-parameter of the public key, default to this option)
-3 use 3 for the E value (using 3 as the E-parameter of the public key)
-engine e use engine E, possibly a hardware device. (Generating a key pair using a th
RSA is a public-key cryptography algorithm, RSA cipher is the code of the text of the number of the E-time to find the result of MoD N. The following article mainly introduces you to the Python use of RSA Library to do public key decryption method tutorial, the text through

, the cost of USB keys issued by China Merchants Bank is 88 yuan, while that of ICBC is 76 yuan, the cost of adding these new security measures is still quite large. In practical applications, it is feasible to require a low-cost alternative solution.
So how can we operate the existing USB Key more securely? My suggestions are as follows:
1. confirm with the bank that the digital certificate in the USB Key
