Aspose.Cells - Encrypting Excel Files

To apply encryption to Excel files using Aspose.Cells for Java in Ruby, simply invoke the Encrypt module.

Ruby Code

data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'

# Instantiating a Workbook object using an Excel file path
workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

# Password‑protect the file.
workbook.getSettings().setPassword("1234")

encryption_type = Rjb::import('com.aspose.cells.EncryptionType')       

# Specify XOR encryption type.
workbook.setEncryptionOptions(encryption_type.XOR, 40)

# Specify Strong Encryption type (RC4, Microsoft Strong Cryptographic Provider).
workbook.setEncryptionOptions(encryption_type.STRONG_CRYPTOGRAPHIC_PROVIDER, 128)

# Saving the modified Excel file in the default (that is Excel 2003) format
workbook.save(data_dir + "encrypt.xls")

puts "Encryption applied; please check the output file."
