Method from org.apache.pdfbox.pdmodel.encryption.ProtectionPolicy Detail:
public int getEncryptionKeyLength() { return encryptionKeyLength; } Get the length of the secrete key that will be used to encrypt document data.
public void setEncryptionKeyLength(int l) { if(l!=40 && l!=128) { throw new RuntimeException("Invalid key length '" + l + "' value must be 40 or 128!"); } encryptionKeyLength = l; } set the length in (bits) of the secret key that will be used to encrypt document data. The default value is 40 bits, which provides a low security level but is compatible with old versions of Acrobat Reader.
