Yankee Clipper X supports option of encrypting clippings. This option is available only in BoilerPlate mode. There is no limitation on how many collections can be encrypted, however all collections must be encrypted with the same password. This means that when encrypting BoilerPlate collection, other the first one, the password with witch it is to be encrypted must be the same as the password with which all previous collections were encrypted.
