Summary:The invention discloses a one-to-one key document compression encryption and decryption security tool implementation method. The method comprises the steps that an original file needing to be compressed and encrypted is selected; the compression algorithm module and the first encryption algorithm module are used for carrying out interference algorithm on an original file and then carrying out compression processing, the second encryption algorithm module is used for carrying out encryption again and obtaining a file end record, and the third encryption algorithm module is used for encrypting the file end record. In the encryption process, a one-to-one secret key is used for encryption and then compression is carried out again; and in the decompression process, the file information encrypted and compressed again is decrypted and decompressed by using the encrypted one-to-one secret key record, and is decrypted and decompressed through the compression and reduction algorithm module, and all original files are o
