PDFKeyLengthEnum

PDFKeyLengthEnum enumeration constants are used to set the encryption key length when the exported PDF file is encrypted with the RC4 algorithm.

Note: All values except PDFKL_40Bit require PDF version 1.4 or greater (see IPDFExportFeatures::PDFVersion).

typedef enum {
 PDFKL_40Bit = 5,
 PDFKL_48Bit = 6,
 PDFKL_56Bit = 7,
 PDFKL_64Bit = 8,
 PDFKL_72Bit = 9,
 PDFKL_80Bit = 10,
 PDFKL_88Bit = 11,
 PDFKL_96Bit = 12,
 PDFKL_104Bit = 13,
 PDFKL_112Bit = 14,
 PDFKL_120Bit = 15,
 PDFKL_128Bit = 16
} PDFKeyLengthEnum;
