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 and in the last beta versions is Single DES. Tripple DES is not supported until now. 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.
