Hi,'
I have a requirement of writing data to xlsx encrypted(protected file with
password) file and I have used the following code snippet from apache to do
the same
POIFSFileSystem fs = new POIFSFileSystem();
EncryptionInfo info = new EncryptionInfo(fs, EncryptionMode.agile);
// EncryptionInfo info = new EncryptionInfo(fs, EncryptionMode.agile,
CipherAlgorithm.aes192, HashAlgorithm.sha384, -1, -1, null);
Encryptor enc = info.getEncryptor();
enc.confirmPassword("foobaa");
OPCPackage opc = OPCPackage.open(new File("..."), PackageAccess.READ_WRITE);
OutputStream os = enc.getDataStream(fs);
opc.save(os);
opc.close();
FileOutputStream fos = new FileOutputStream("...");
fs.writeFilesystem(fos);
fos.close();
I got the error at EncryptionInfo class for EncryptionMode.agile. Iam using
POI3.9. Could anyone please help
