Summary:The invention provides a data sharing method and device, equipment and a storage medium. The method is applied to encryption party equipment, and comprises the following steps: acquiring to-be-encrypted data from a block chain, wherein the to-be-encrypted data is shared data; acquiring a symmetric key based on a preset Hash algorithm and the to-be-encrypted data; encrypting the to-be-encrypted data by using the symmetric key to obtain target encrypted data, and storing the target encrypted data to the block chain; performing encryption calculation on the symmetric key by adopting a preset asymmetric encryption algorithm to generate a target encrypted public key, and generating key information based on the target encrypted public key; sending the secret key information to a relational database; the secret key information is used for indicating the decryption party equipment to determine the target decryption data as source data, so that the encryption party equipment can share the to-be-encrypted data; the tar
