Resource encryption method, system and device and computer readable storage medium

The embodiment of the invention relates to the technical field of multimedia communication, and discloses a resource encryption method. According to the invention, the information length of to-be-encrypted information is calculated, byte splitting is carried out on the to-be-encrypted information according to a preset byte splitting number to obtain a byte information set, according to a pre-constructed filling character, by a pre-constructed filling method, each piece of sub-byte information in the sub-byte information set is filled to obtain a filling information set, the filling informationset is encrypted according to a Base64 algorithm to obtain an original encrypted information set, and bytes of each piece of original encrypted information in the original encrypted information set is removed according to the byte splitting number and a preset removal method to obtain a primary encrypted information set, and combination operation on each piece of primary encrypted information inthe primary encrypted info
