PIN code encryption method and device, equipment and storage medium

The invention relates to the technical field of passwords, and provides a PIN code encryption method and device, equipment and a storage medium, and the method comprises the steps: constructing an initialization matrix and a random number; obtaining an initial PIN code, filling the initial PIN code into the initialization matrix, and extracting the encryption vector set according to the first matrix to generate an encryption storage value; obtaining a verification PIN code, filling the verification PIN code into the initialization matrix, and generating an encrypted verification value; and comparing the encrypted storage value with the encrypted verification value, and performing verification. The method has the beneficial effects that the initial matrix is constructed, the primary PIN code and the verification PIN code are respectively filled into the initial matrix, the encryption vector set is used for encryption, the primary PIN code and the verification PIN code are encrypted in a lattice form, and the d
