<P>PROBLEM TO BE SOLVED: To generate an encryption document in which only a desired part is encrypted without creating a plaintext document. <P>SOLUTION: When a user inputs a delimited length of a character string and further inputs a conversion order thereon, an option as to whether an encryption is required is displayed to allow the user to select it. If the encryption is selected, the input character string is encrypted and converted into a fixed character string, while if non-encryption is selected, the character string is converted into a fixed character string, without encryption, to create document data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
