## Member Function Documentation

## ◆ getEncryptionAlgorithms()

sequence< ::com::sun::star::beans::NamedValue > getEncryptionAlgorithms | ( |  | ) |

allows to get the encryption algorithms of the object.

## ◆ setEncryptionAlgorithms()

void setEncryptionAlgorithms | ( | [in] sequence< ::com::sun::star::beans::NamedValue > | aAlgorithms | ) |
raises | ( | ::com::sun::star::lang::IllegalArgumentException ) |  |  |

allows to set the encryption algorithms for the object.

The algorithms will of course be used only for streams that have been marked to be encrypted. If no stream in the storage is marked to be encrypted, the algorithms-related information may have no effect to the result package.

The following values could be part of the provided sequence:

StartKeyGenerationAlgorithm
  specifies the algorithm that was used to generate the EncryptionKey from the original password; in case the contents should be decrypted, the algorithm might be already known by the object; if a different one is set an exception should be thrown to indicate the error; it should take values from com::sun::star::xml:crypto::DigestID.
KeyDerivationFunction
  specifies the algorithm that was used to derive the encryption key from the password; it is applied to the result of the StartKeyGenerationAlgorithm; it should take values from com::sun::star::xml:crypto::KDFID.
EncryptionAlgorithm
  specifies the algorithm that should be used to encrypt/decrypt the contents; in case the contents should be decrypted, the algorithm might be already known by the object; if a different one is set an exception should be thrown to indicate the error; it should take values from com::sun::star::xml:crypto::CipherID.
ChecksumAlgorithm
  specifies the algorithm that was used to generate the checksum of the encrypted data; in case the contents should be decrypted, the algorithm might be already known by the object; if a different one is set an exception should be thrown to indicate the error; it should take values from com::sun::star::xml:crypto::DigestID.

## ◆ setGpgProperties()

void setGpgProperties | ( | [in] sequence< sequence< ::com::sun::star::beans::NamedValue > > | aProps | ) |
raises | ( | ::com::sun::star::lang::IllegalArgumentException ) |  |  |

set OpenPGP-specific encryption properties

When provided, switch ODF package encryption to OpenPGP.

For each recipient, add one sequence of named values, each of the same structure. The following values could be part of that provided sequence:

KeyId
  specifies OpenPGP key ID or fingerprint of the public key used to encrypt this session key against
KeyPacket
  (optional) public key packet of the key used to encrypt
CipherValue
  OpenPGP-encrypted session key for this recipient
