<P>PROBLEM TO BE SOLVED: To provide an electronic signature generating method and an electronic signature generating program capable of flexibly expanding an encryption method to use for signature generation. <P>SOLUTION: An electric signature generator 11 comprises a storage unit which stores IC card management information and a driver serving as a complement to the functions of an IC card. On the basis of the IC card management information, the electric signature generator 11 determines whether information obtained by compressing a document to be signed electrically to a fixed length is to be signed by the electric signature generator or by an IC card 13 connected via an IC card reader and writer 12, and generates on the basis of the determination result the information obtained by compressing the document to be signed electrically to a fixed length, using the driver serving as a complement to the functions of the IC card. <P>COPYRIGHT: (C)2013,JPO&INPIT |
