    CryptFilterDecrypter
    Implements Version 4 standard decryption, whereby the Encrypt dictionary contains a list of named 'crypt filters', each of which is the equivalent of a PDFDecrypter.
    EncryptionUnsupportedByPlatformException
    Identifies that the specified encryption mechanism, though supported by the product, is not supported by the platform that it is running on; i.e., that either the JCE does not support a required cipher or that its policy is such that a key of a given length can not be used.
    EncryptionUnsupportedByProductException
    Identifies that the specified encryption mechanism is not supported by this product, that is, PDFRenderer, as opposed to a limitation in the platform.
    IdentityDecrypter
    Performs identity decryption; that is, inputs aren't encrypted and are returned right back.
    PDFAuthenticationFailureException
    Identifies that the supplied password was incorrect or non-existent and required.
    PDFDecrypter
    A decrypter decrypts streams and strings in a PDF document.
    PDFDecrypterFactory

    StandardDecrypter
    Standard simple decrypter for versions 1, 2 and 4 of the Standard password-based decryption mechanisms, as described in section 3.5 of the PDF Reference version 1.7.
    StandardDecrypter.EncryptionAlgorithm
    Describes an encryption algorithm to be used, declaring not only the cipher type, but also key generation techniques
    UnsupportedEncryptionException
    Identifies that the specified encryption mechanism is not supported by this product or platform.
