CalculateStreamLength()

size_t PdfEncryptAESV2::CalculateStreamLength ( size_t  length ) const

overridevirtual

Calculate stream size

Implements mm::PdfEncrypt.

CalculateStreamOffset()

size_t PdfEncryptAESV2::CalculateStreamOffset ( ) const

overridevirtual

Calculate stream offset

Implements mm::PdfEncrypt.

CreateEncryptionInputStream()

unique_ptr< PdfInputStream > PdfEncryptAESV2::CreateEncryptionInputStream ( PdfInputStream &  inputStream, size_t  inputLen  )

overridevirtual

Create a PdfInputStream that decrypts all data read from it using the current settings of the PdfEncrypt object.

Warning: Currently only RC4 based encryption is supported using output streams!

Parameters

inputStream

the created PdfInputStream reads all decrypted data to this input stream.

Returns

a PdfInputStream that decrypts all data.

Implements mm::PdfEncrypt.

CreateEncryptionOutputStream()

unique_ptr< PdfOutputStream > PdfEncryptAESV2::CreateEncryptionOutputStream ( PdfOutputStream &  outputStream )

overridevirtual

Create a PdfOutputStream that encrypts all data written to it using the current settings of the PdfEncrypt object.

Warning: Currently only RC4 based encryption is supported using output streams!

Parameters

outputStream

the created PdfOutputStream writes all encrypted data to this output stream.

Returns

a PdfOutputStream that encrypts all data.

Implements mm::PdfEncrypt.
