Sets the certificate encryption options for the document.
Sets the certificate encryption options for the document. An array of one or more public certificates must be provided together with an array of the same size for the permissions for each certificate. The open permissions for the document can be AllowPrinting, AllowModifyContents, AllowCopy, AllowModifyAnnotations, AllowFillIn, AllowScreenReaders, AllowAssembly and AllowDegradedPrinting. The permissions can be combined by ORing them. Optionally DO_NOT_ENCRYPT_METADATA can be ORed to output the metadata in cleartext See EncryptionConstants
certs | the public certificates to be used for the encryption |
permissions | the user permissions for each of the certificates |
encryptionAlgorithm | the type of encryption. It can be one of STANDARD_ENCRYPTION_40, STANDARD_ENCRYPTION_128, ENCRYPTION_AES128 or ENCRYPTION_AES256. |
