In FreeMind, the whole map or single branches may be encrypted. An encrypted branch has a padlock icon. Encryption is available since FreeMind 0.8.0. Using encryption TODO: Menu entries. Format: To achieve this, do that. Encryption algorithm The encryption algorith used in FreeMind 0.8.0 is Triple DES on Java 1.6 while DES on Java 1.4 and 1.5. Both are symmetric-key algorithms built in Java. Troubleshooting Problem: Maps encrypted with FreeMind running on Java Runtime Environment JRE 1.4 and JRE 1.5 cannot be opened with FreeMind running on Java Runtime Environment JRE 1.6. Concerned operating systems: Linux, Windows, and possibly other. Concerned FreeMind versions: 0.8.0, 0.9.0 beta 9. Solution: A provisional solution is to stick with Java Runtime Environment JRE 1.4 or JRE 1.5. Detail: There is a bug in the PBE key getkey.getAlgorithm() method in JRE 1.4> key.getAlgorithm() returns PBEWithMD5AndDES instead of PBEWithMD5AndTripleDES.
