The invention relates to the technical field of data security, and particularly discloses a file transmission method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: converting a file into a data input stream, and reading a plurality of original arrays corresponding to the file from the data input stream; performing coding processing on each original array to obtain a coding array corresponding to each original array; aiming at each coding array, encrypting the coding array to obtain an encrypted array, and determining a sub-output stream for outputting the encrypted array; determining a transmission message corresponding to the coding array based on the sub-output streams and an encryption key used in the encryption processing process; and sequentially transmitting the transmission message corresponding to each coding array. By using the method, the transmission security of the oversized file can be ensured, and the transmission effici
