Data encryption method and device and computing equipment

The invention discloses a data encryption method and device and computing equipment. The data encryption method comprises the following steps: acquiring to-be-encrypted data; for each bit in the data, converting the initial form representation of the bit into binary representation, then carrying out cyclic shift for a plurality of times, and converting the shifted binary data into the initial form representation of the data to obtain shifted data; carrying out Fibonacci coding on the shift data to obtain Fibonacci coded data; encoding the carrier image to obtain image encoding data, and selecting a part of data from the image encoding data as a secret key; encrypting the Fibonacci coded data by using the key to obtain encrypted data, and writing the encrypted data into the carrier image data to obtain encrypted image data; and storing the encrypted image data in a cache. The invention also discloses a corresponding device and computing equipment. 本发明公开了一种数据加密方法、装置与计算设备。上述数据加密方法包括步骤：获取待加密的数据；对于数据中的每一位，将其由初始形式表
